If **any** of these are omitted we will likely close your issue, do **not** ignore them.
- Client netmap dump (see below)
- Policy configuration
- Headscale configuration
- Headscale log (with `trace` enabled)
Dump the netmap of tailscale clients:
`tailscale debug netmap > DESCRIPTIVE_NAME.json`
Dump the status of tailscale clients:
`tailscale status --json > DESCRIPTIVE_NAME.json`
Get the logs of a Tailscale client that is not working as expected.
`tailscale debug daemon-logs`

FILE: .github/label-response/needs-more-info.md
================================================
Thank you for taking the time to report this issue.
To help us investigate and resolve this, we need more information. Please provide the following:
> [!TIP]
> Most issues turn out to be configuration errors rather than bugs. We encourage you to discuss your problem in our [Discord community](https://discord.gg/c84AZQhmpx) **before** opening an issue. The community can often help identify misconfigurations quickly, saving everyone time.
## Required Information
### Environment Details
- **Headscale version**: (run `headscale version`)
- **Tailscale client version**: (run `tailscale version`)
- **Operating System**: (e.g., Ubuntu 24.04, macOS 14, Windows 11)
- **Deployment method**: (binary, Docker, Kubernetes, etc.)
- **Reverse proxy**: (if applicable: nginx, Traefik, Caddy, etc. - include configuration)
### Debug Information
Please follow our [Debugging and Troubleshooting Guide](https://headscale.net/stable/ref/debug/) and provide:
1. **Client netmap dump** (from affected Tailscale client):
```bash
tailscale debug netmap > netmap.json
```
2. **Client status dump** (from affected Tailscale client):
```bash
tailscale status --json > status.json
```
3. **Tailscale client logs** (if experiencing client issues):
```bash
tailscale debug daemon-logs
```
> [!IMPORTANT]
> We need logs from **multiple nodes** to understand the full picture:
>
> - The node(s) initiating connections
> - The node(s) being connected to
>
> Without logs from both sides, we cannot diagnose connectivity issues.
4. **Headscale server logs** with `log.level: trace` enabled
5. **Headscale configuration** (with sensitive values redacted - see rules below)
6. **ACL/Policy configuration** (if using ACLs)
7. **Proxy/Docker configuration** (if applicable - nginx.conf, docker-compose.yml, Traefik config, etc.)
## Formatting Requirements
- **Attach long files** - Do not paste large logs or configurations inline. Use GitHub file attachments or GitHub Gists.
- **Use proper Markdown** - Format code blocks, logs, and configurations with appropriate syntax highlighting.
- **Structure your response** - Use the headings above to organize your information clearly.
## Redaction Rules
> [!CAUTION]
> **Replace, do not remove.** Removing information makes debugging impossible.
When redacting sensitive information:
- ✅ **Replace consistently** - If you change `alice@company.com` to `user1@example.com`, use `user1@example.com` everywhere (logs, config, policy, etc.)
- ✅ **Use meaningful placeholders** - `user1@example.com`, `bob@example.com`, `my-secret-key` are acceptable
- ❌ **Never remove information** - Gaps in data prevent us from correlating events across logs
- ❌ **Never redact IP addresses** - We need the actual IPs to trace network paths and identify issues
**If redaction rules are not followed, we will be unable to debug the issue and will have to close it.**
---
**Note:** This issue will be automatically closed in 3 days if no additional information is provided. Once you reply with the requested information, the `needs-more-info` label will be removed automatically.

Open source implementation of the Tailscale control server.
Headscale aims to implement a self-hosted, open source alternative to the
Tailscale control server. Headscale's goal is to provide self-hosters and
hobbyists with an open-source server they can use for their projects and
labs. It implements a narrow scope, a single Tailscale network (tailnet),
suitable for a personal use, or a small open-source organisation.

# AGENTS.md
This file provides guidance to AI agents when working with code in this repository.
## Overview
Headscale is an open-source implementation of the Tailscale control server written in Go. It provides self-hosted coordination for Tailscale networks (tailnets), managing node registration, IP allocation, policy enforcement, and DERP routing.
## Development Commands
### Quick Setup
```bash
# Recommended: Use Nix for dependency management
nix develop
# Full development workflow
make dev # runs fmt + lint + test + build
```
### Essential Commands
```bash
# Build headscale binary
make build
# Run tests
make test
go test ./... # All unit tests
go test -race ./... # With race detection
# Run specific integration test
go run ./cmd/hi run "TestName" --postgres
# Code formatting and linting
make fmt # Format all code (Go, docs, proto)
make lint # Lint all code (Go, proto)
make fmt-go # Format Go code only
make lint-go # Lint Go code only
# Protocol buffer generation (after modifying proto/)
make generate
# Clean build artifacts
make clean
```
### Integration Testing
```bash
# Use the hi (Headscale Integration) test runner
go run ./cmd/hi doctor # Check system requirements
go run ./cmd/hi run "TestPattern" # Run specific test
go run ./cmd/hi run "TestPattern" --postgres # With PostgreSQL backend
# Test artifacts are saved to control_logs/ with logs and debug data
```
## Pre-Commit Quality Checks
### **MANDATORY: Automated Pre-Commit Hooks with prek**
**CRITICAL REQUIREMENT**: This repository uses [prek](https://prek.j178.dev/) for automated pre-commit hooks. All commits are automatically validated for code quality, formatting, and common issues.
### Initial Setup
When you first clone the repository or enter the nix shell, install the git hooks:
```bash
# Enter nix development environment
nix develop
# Install prek git hooks (one-time setup)
prek install
```
This installs the pre-commit hook at `.git/hooks/pre-commit` which automatically runs all configured checks before each commit.
### Configured Hooks
The repository uses `.pre-commit-config.yaml` with the following hooks:
**Built-in Checks** (optimized fast-path execution):
- `check-added-large-files` - Prevents accidentally committing large files
- `check-case-conflict` - Checks for files that would conflict in case-insensitive filesystems
- `check-executables-have-shebangs` - Ensures executables have proper shebangs
- `check-json` - Validates JSON syntax
- `check-merge-conflict` - Prevents committing files with merge conflict markers
- `check-symlinks` - Checks for broken symlinks
- `check-toml` - Validates TOML syntax
- `check-xml` - Validates XML syntax
- `check-yaml` - Validates YAML syntax
- `detect-private-key` - Detects accidentally committed private keys
- `end-of-file-fixer` - Ensures files end with a newline
- `fix-byte-order-marker` - Removes UTF-8 byte order markers
- `mixed-line-ending` - Prevents mixed line endings
- `trailing-whitespace` - Removes trailing whitespace
**Project-Specific Hooks**:
- `nixpkgs-fmt` - Formats Nix files
- `prettier` - Formats markdown, YAML, JSON, and TOML files
- `golangci-lint` - Runs Go linter with auto-fix on changed files only
### Manual Hook Execution
Run hooks manually without making a commit:
```bash
# Run hooks on staged files only
prek run
# Run hooks on all files in the repository
prek run --all-files
# Run a specific hook
prek run golangci-lint
# Run hooks on specific files
prek run --files path/to/file1.go path/to/file2.go
```
### Workflow Pattern
With prek installed, your normal workflow becomes:
```bash
# 1. Make your code changes
vim hscontrol/state/state.go
# 2. Stage your changes
git add .
# 3. Commit - hooks run automatically
git commit -m "feat: add new feature"
# If hooks fail, they will show which checks failed
# Fix the issues and try committing again
```
### Manual golangci-lint
While golangci-lint runs automatically via prek, you can also run it manually:
```bash
# If you have upstream remote configured (recommended)
golangci-lint run --new-from-rev=upstream/main --timeout=5m --fix
# If you only have origin remote
golangci-lint run --new-from-rev=main --timeout=5m --fix
```
**Important**: Always use `--new-from-rev` to only lint changed files. This prevents formatting the entire repository and keeps changes focused on your actual modifications.
### Skipping Hooks (Not Recommended)
In rare cases where you need to skip hooks (e.g., work-in-progress commits), use:
```bash
git commit --no-verify -m "WIP: work in progress"
```
**WARNING**: Only use `--no-verify` for temporary WIP commits on feature branches. All commits to main must pass all hooks.
### Troubleshooting
**Hook installation issues**:
```bash
# Check if hooks are installed
ls -la .git/hooks/pre-commit
# Reinstall hooks
prek install
```
**Hooks running slow**:
```bash
# prek uses optimized fast-path for built-in hooks
# If running slow, check which hook is taking time with verbose output
prek run -v
```
**Update hook configuration**:
```bash
# After modifying .pre-commit-config.yaml, hooks will automatically use new config
# No reinstallation needed
```

### Core Packages (`hscontrol/`)
**Main Server (`hscontrol/`)**
- `app.go`: Application setup, dependency injection, server lifecycle
- `handlers.go`: HTTP/gRPC API endpoints for management operations
- `grpcv1.go`: gRPC service implementation for headscale API
- `poll.go`: **Critical** - Handles Tailscale MapRequest/MapResponse protocol
- `noise.go`: Noise protocol implementation for secure client communication
- `auth.go`: Authentication flows (web, OIDC, command-line)
- `oidc.go`: OpenID Connect integration for user authentication
**State Management (`hscontrol/state/`)**
- `state.go`: Central coordinator for all subsystems (database, policy, IP allocation, DERP)
- `node_store.go`: **Performance-critical** - In-memory cache with copy-on-write semantics
- Thread-safe operations with deadlock detection
- Coordinates between database persistence and real-time operations
**Database Layer (`hscontrol/db/`)**
- `db.go`: Database abstraction, GORM setup, migration management
- `node.go`: Node lifecycle, registration, expiration, IP assignment
- `users.go`: User management, namespace isolation
- `api_key.go`: API authentication tokens
- `preauth_keys.go`: Pre-authentication keys for automated node registration
- `ip.go`: IP address allocation and management
- `policy.go`: Policy storage and retrieval
- Schema migrations in `schema.sql` with extensive test data coverage
**CRITICAL DATABASE MIGRATION RULES**:
1. **NEVER reorder existing migrations** - Migration order is immutable once committed
2. **ONLY add new migrations to the END** of the migrations array
3. **NEVER disable foreign keys** in new migrations - no new migrations should be added to `migrationsRequiringFKDisabled`
4. **Migration ID format**: `YYYYMMDDHHSS-short-description` (timestamp + descriptive suffix)
- Example: `202511131500-add-user-roles`
- The timestamp must be chronologically ordered
5. **New migrations go after the comment** "As of 2025-07-02, no new IDs should be added here"
6. If you need to rename a column that other migrations depend on:
- Accept that the old column name will exist in intermediate migration states
- Update code to work with the new column name
- Let AutoMigrate create the new column if needed
- Do NOT try to rename columns that later migrations reference
**Policy Engine (`hscontrol/policy/`)**
- `policy.go`: Core ACL evaluation logic, HuJSON parsing
- `v2/`: Next-generation policy system with improved filtering
- `matcher/`: ACL rule matching and evaluation engine
- Determines peer visibility, route approval, and network access rules
- Supports both file-based and database-stored policies
**Network Management (`hscontrol/`)**
- `derp/`: DERP (Designated Encrypted Relay for Packets) server implementation
- NAT traversal when direct connections fail
- Fallback relay for firewall-restricted environments
- `mapper/`: Converts internal Headscale state to Tailscale's wire protocol format
- `tail.go`: Tailscale-specific data structure generation
- `routes/`: Subnet route management and primary route selection
- `dns/`: DNS record management and MagicDNS implementation
**Utilities & Support (`hscontrol/`)**
- `types/`: Core data structures, configuration, validation
- `util/`: Helper functions for networking, DNS, key management
- `templates/`: Client configuration templates (Apple, Windows, etc.)
- `notifier/`: Event notification system for real-time updates
- `metrics.go`: Prometheus metrics collection
- `capver/`: Tailscale capability version management
### Key Subsystem Interactions
**Node Registration Flow**
1. **Client Connection**: `noise.go` handles secure protocol handshake
2. **Authentication**: `auth.go` validates credentials (web/OIDC/preauth)
3. **State Creation**: `state.go` coordinates IP allocation via `db/ip.go`
4. **Storage**: `db/node.go` persists node, `NodeStore` caches in memory
5. **Network Setup**: `mapper/` generates initial Tailscale network map
**Ongoing Operations**
1. **Poll Requests**: `poll.go` receives periodic client updates
2. **State Updates**: `NodeStore` maintains real-time node information
3. **Policy Application**: `policy/` evaluates ACL rules for peer relationships
4. **Map Distribution**: `mapper/` sends network topology to all affected clients
**Route Management**
1. **Advertisement**: Clients announce routes via `poll.go` Hostinfo updates
2. **Storage**: `db/` persists routes, `NodeStore` caches for performance
3. **Approval**: `policy/` auto-approves routes based on ACL rules
4. **Distribution**: `routes/` selects primary routes, `mapper/` distributes to peers
### Command-Line Tools (`cmd/`)
**Main Server (`cmd/headscale/`)**
- `headscale.go`: CLI parsing, configuration loading, server startup
- Supports daemon mode, CLI operations (user/node management), database operations
**Integration Test Runner (`cmd/hi/`)**
- `main.go`: Test execution framework with Docker orchestration
- `run.go`: Individual test execution with artifact collection
- `doctor.go`: System requirements validation
- `docker.go`: Container lifecycle management
- Essential for validating changes against real Tailscale clients
### Generated & External Code
**Protocol Buffers (`proto/` → `gen/`)**
- Defines gRPC API for headscale management operations
- Client libraries can generate from these definitions
- Run `make generate` after modifying `.proto` files
**Integration Testing (`integration/`)**
- `scenario.go`: Docker test environment setup
- `tailscale.go`: Tailscale client container management
- Individual test files for specific functionality areas
- Real end-to-end validation with network isolation
### Critical Performance Paths
**High-Frequency Operations**
1. **MapRequest Processing** (`poll.go`): Every 15-60 seconds per client
2. **NodeStore Reads** (`node_store.go`): Every operation requiring node data
3. **Policy Evaluation** (`policy/`): On every peer relationship calculation
4. **Route Lookups** (`routes/`): During network map generation
**Database Write Patterns**
- **Frequent**: Node heartbeats, endpoint updates, route changes
- **Moderate**: User operations, policy updates, API key management
- **Rare**: Schema migrations, bulk operations
### Configuration & Deployment
**Configuration** (`hscontrol/types/config.go`)\*\*
- Database connection settings (SQLite/PostgreSQL)
- Network configuration (IP ranges, DNS settings)
- Policy mode (file vs database)
- DERP relay configuration
- OIDC provider settings
**Key Dependencies**
- **GORM**: Database ORM with migration support
- **Tailscale Libraries**: Core networking and protocol code
- **Zerolog**: Structured logging throughout the application
- **Buf**: Protocol buffer toolchain for code generation
### Development Workflow Integration
The architecture supports incremental development:
- **Unit Tests**: Focus on individual packages (`*_test.go` files)
- **Integration Tests**: Validate cross-component interactions
- **Database Tests**: Extensive migration and data integrity validation
- **Policy Tests**: ACL rule evaluation and edge cases
- **Performance Tests**: NodeStore and high-frequency operation validation
## Integration Testing System
### Overview
Headscale uses Docker-based integration tests with real Tailscale clients to validate end-to-end functionality. The integration test system is complex and requires specialized knowledge for effective execution and debugging.
### **MANDATORY: Use the headscale-integration-tester Agent**
**CRITICAL REQUIREMENT**: For ANY integration test execution, analysis, troubleshooting, or validation, you MUST use the `headscale-integration-tester` agent. This agent contains specialized knowledge about:
- Test execution strategies and timing requirements

### Quick Reference Commands
```bash
# Check system requirements (always run first)
go run ./cmd/hi doctor
# Run single test (recommended for development)
go run ./cmd/hi run "TestName"
# Use PostgreSQL for database-heavy tests
go run ./cmd/hi run "TestName" --postgres
# Pattern matching for related tests
go run ./cmd/hi run "TestPattern*"
# Run multiple tests concurrently (each gets isolated run ID)
go run ./cmd/hi run "TestPingAllByIP" &
go run ./cmd/hi run "TestACLAllowUserDst" &
go run ./cmd/hi run "TestOIDCAuthenticationPingAll" &
```
**Concurrent Execution Support**:
The test runner supports running multiple tests concurrently on the same Docker daemon:
- Each test run gets a **unique Run ID** (format: `YYYYMMDD-HHMMSS-{6-char-hash}`)
- All containers are labeled with `hi.run-id` for isolation
- Container names include the run ID for easy identification (e.g., `ts-{runID}-1-74-{hash}`)
- Dynamic port allocation prevents port conflicts between concurrent runs
- Cleanup only affects containers belonging to the specific run ID
- Log directories are isolated per run: `control_logs/{runID}/`
**Critical Notes**:
- Tests generate ~100MB of logs per run in `control_logs/`
- Running many tests concurrently may cause resource contention (CPU/memory)
- Clean stale containers periodically: `docker system prune -f`
### Test Artifacts Location
All test runs save comprehensive debugging artifacts to `control_logs/TIMESTAMP-ID/` including server logs, client logs, database dumps, MapResponse protocol data, and Prometheus metrics.
**For all integration test work, use the headscale-integration-tester agent - it contains the complete knowledge needed for effective testing and debugging.**
## NodeStore Implementation Details
**Key Insight from Recent Work**: The NodeStore is a critical performance optimization that caches node data in memory while ensuring consistency with the database. When working with route advertisements or node state changes:
1. **Timing Considerations**: Route advertisements need time to propagate from clients to server. Use `require.EventuallyWithT()` patterns in tests instead of immediate assertions.
2. **Synchronization Points**: NodeStore updates happen at specific points like `poll.go:420` after Hostinfo changes. Ensure these are maintained when modifying the polling logic.
3. **Peer Visibility**: The NodeStore's `peersFunc` determines which nodes are visible to each other. Policy-based filtering is separate from monitoring visibility - expired nodes should remain visible for debugging but marked as expired.
## Testing Guidelines
### Integration Test Patterns
#### **CRITICAL: EventuallyWithT Pattern for External Calls**
**All external calls in integration tests MUST be wrapped in EventuallyWithT blocks** to handle eventual consistency in distributed systems. External calls include:
- `client.Status()` - Getting Tailscale client status
- `client.Curl()` - Making HTTP requests through clients
- `client.Traceroute()` - Running network diagnostics
- `headscale.ListNodes()` - Querying headscale server state
- Any other calls that interact with external systems or network operations
**Key Rules**:
1. **Never use bare `require.NoError(t, err)` with external calls** - Always wrap in EventuallyWithT
2. **Keep related assertions together** - If multiple assertions depend on the same external call, keep them in the same EventuallyWithT block
3. **Split unrelated external calls** - Different external calls should be in separate EventuallyWithT blocks
4. **Never nest EventuallyWithT calls** - Each EventuallyWithT should be at the same level
5. **Declare shared variables at function scope** - Variables used across multiple EventuallyWithT blocks must be declared before first use
**Examples**:
```go
// CORRECT: External call wrapped in EventuallyWithT
assert.EventuallyWithT(t, func(c *assert.CollectT) {
status, err := client.Status()
assert.NoError(c, err)
// Related assertions using the same status call
for _, peerKey := range status.Peers() {
peerStatus := status.Peer[peerKey]
assert.NotNil(c, peerStatus.PrimaryRoutes)
requirePeerSubnetRoutesWithCollect(c, peerStatus, expectedRoutes)
}
}, 5*time.Second, 200*time.Millisecond, "Verifying client status and routes")
// INCORRECT: Bare external call without EventuallyWithT
status, err := client.Status() // ❌ Will fail intermittently
require.NoError(t, err)
// CORRECT: Separate EventuallyWithT for different external calls
// First external call - headscale.ListNodes()
assert.EventuallyWithT(t, func(c *assert.CollectT) {
nodes, err := headscale.ListNodes()
assert.NoError(c, err)
assert.Len(c, nodes, 2)
requireNodeRouteCountWithCollect(c, nodes[0], 2, 2, 2)
}, 10*time.Second, 500*time.Millisecond, "route state changes should propagate to nodes")
// Second external call - client.Status()
assert.EventuallyWithT(t, func(c *assert.CollectT) {
status, err := client.Status()
assert.NoError(c, err)
for _, peerKey := range status.Peers() {
peerStatus := status.Peer[peerKey]
requirePeerSubnetRoutesWithCollect(c, peerStatus, []netip.Prefix{tsaddr.AllIPv4(), tsaddr.AllIPv6()})
}
}, 10*time.Second, 500*time.Millisecond, "routes should be visible to client")
// INCORRECT: Multiple unrelated external calls in same EventuallyWithT
assert.EventuallyWithT(t, func(c *assert.CollectT) {
nodes, err := headscale.ListNodes() // ❌ First external call
assert.NoError(c, err)
status, err := client.Status() // ❌ Different external call - should be separate
assert.NoError(c, err)
}, 10*time.Second, 500*time.Millisecond, "mixed calls")
// CORRECT: Variable scoping for shared data
var (
srs1, srs2, srs3 *ipnstate.Status
clientStatus *ipnstate.Status
srs1PeerStatus *ipnstate.PeerStatus
)
assert.EventuallyWithT(t, func(c *assert.CollectT) {
srs1 = subRouter1.MustStatus() // = not :=
srs2 = subRouter2.MustStatus()
clientStatus = client.MustStatus()
srs1PeerStatus = clientStatus.Peer[srs1.Self.PublicKey]
// assertions...
}, 5*time.Second, 200*time.Millisecond, "checking router status")
// CORRECT: Wrapping client operations
assert.EventuallyWithT(t, func(c *assert.CollectT) {
result, err := client.Curl(weburl)
assert.NoError(c, err)
assert.Len(c, result, 13)
}, 5*time.Second, 200*time.Millisecond, "Verifying HTTP connectivity")
assert.EventuallyWithT(t, func(c *assert.CollectT) {
tr, err := client.Traceroute(webip)
assert.NoError(c, err)
assertTracerouteViaIPWithCollect(c, tr, expectedRouter.MustIPv4())
}, 5*time.Second, 200*time.Millisecond, "Verifying network path")
```
**Helper Functions**:
- Use `requirePeerSubnetRoutesWithCollect` instead of `requirePeerSubnetRoutes` inside EventuallyWithT
- Use `requireNodeRouteCountWithCollect` instead of `requireNodeRouteCount` inside EventuallyWithT
- Use `assertTracerouteViaIPWithCollect` instead of `assertTracerouteViaIP` inside EventuallyWithT
```go
// Node route checking by actual node properties, not array position
var routeNode *v1.Node
for _, node := range nodes {
if nodeIDStr := fmt.Sprintf("%d", node.GetId()); expectedRoutes[nodeIDStr] != "" {
routeNode = node
break
}
}
```
### Running Problematic Tests
- Some tests require significant time (e.g., `TestNodeOnlineStatus` runs for 12 minutes)
- Infrastructure issues like disk space can cause test failures unrelated to code changes
- Use `--postgres` flag when testing database-heavy scenarios
## Quality Assurance and Testing Requirements
### **MANDATORY: Always Use Specialized Testing Agents**
**CRITICAL REQUIREMENT**: For ANY task involving testing, quality assurance, review, or validation, you MUST use the appropriate specialized agent at the END of your task list. This ensures comprehensive quality validation and prevents regressions.
**Required Agents for Different Task Types**:
1. **Integration Testing**: Use `headscale-integration-tester` agent for:
- Running integration tests with `cmd/hi`
- Analyzing test failures and artifacts
- Troubleshooting Docker-based test infrastructure
- Validating end-to-end functionality changes
2. **Quality Control**: Use `quality-control-enforcer` agent for:
- Code review and validation
- Ensuring best practices compliance
- Preventing common pitfalls and anti-patterns
- Validating architectural decisions
**Agent Usage Pattern**: Always add the appropriate agent as the FINAL step in any task list to ensure quality validation occurs after all work is complete.
### Integration Test Debugging Reference
Test artifacts are preserved in `control_logs/TIMESTAMP-ID/` including:
- Headscale server logs (stderr/stdout)
- Tailscale client logs and status
- Database dumps and network captures
- MapResponse JSON files for protocol debugging
**For integration test issues, ALWAYS use the headscale-integration-tester agent - do not attempt manual debugging.**
## EventuallyWithT Pattern for Integration Tests
### Overview
EventuallyWithT is a testing pattern used to handle eventual consistency in distributed systems. In Headscale integration tests, many operations are asynchronous - clients advertise routes, the server processes them, updates propagate through the network. EventuallyWithT allows tests to wait for these operations to complete while making assertions.
### External Calls That Must Be Wrapped
The following operations are **external calls** that interact with the headscale server or tailscale clients and MUST be wrapped in EventuallyWithT:
- `headscale.ListNodes()` - Queries server state
- `client.Status()` - Gets client network status
- `client.Curl()` - Makes HTTP requests through the network
- `client.Traceroute()` - Performs network diagnostics
- `client.Execute()` when running commands that query state
- Any operation that reads from the headscale server or tailscale client
### Operations That Must NOT Be Wrapped
The following are **blocking operations** that modify state and should NOT be wrapped in EventuallyWithT:
- `tailscale set` commands (e.g., `--advertise-routes`, `--exit-node`)
- Any command that changes configuration or state
- Use `client.MustStatus()` instead of `client.Status()` when you just need the ID for a blocking operation
### Five Key Rules for EventuallyWithT
1. **One External Call Per EventuallyWithT Block**
- Each EventuallyWithT should make ONE external call (e.g., ListNodes OR Status)
- Related assertions based on that single call can be grouped together
- Unrelated external calls must be in separate EventuallyWithT blocks
2. **Variable Scoping**
- Declare variables that need to be shared across EventuallyWithT blocks at function scope
- Use `=` for assignment inside EventuallyWithT, not `:=` (unless the variable is only used within that block)
- Variables declared with `:=` inside EventuallyWithT are not accessible outside
3. **No Nested EventuallyWithT**
- NEVER put an EventuallyWithT inside another EventuallyWithT
- This is a critical anti-pattern that must be avoided
4. **Use CollectT for Assertions**
- Inside EventuallyWithT, use `assert` methods with the CollectT parameter
- Helper functions called within EventuallyWithT must accept `*assert.CollectT`
5. **Descriptive Messages**
- Always provide a descriptive message as the last parameter
- Message should explain what condition is being waited for
### Correct Pattern Examples
```go
// CORRECT: Blocking operation NOT wrapped
for _, client := range allClients {
status := client.MustStatus()
command := []string{
"tailscale",
"set",
"--advertise-routes=" + expectedRoutes[string(status.Self.ID)],
}
_, _, err = client.Execute(command)
require.NoErrorf(t, err, "failed to advertise route: %s", err)
}
// CORRECT: Single external call with related assertions
var nodes []*v1.Node
assert.EventuallyWithT(t, func(c *assert.CollectT) {
nodes, err = headscale.ListNodes()
assert.NoError(c, err)
assert.Len(c, nodes, 2)
requireNodeRouteCountWithCollect(c, nodes[0], 2, 2, 2)
}, 10*time.Second, 500*time.Millisecond, "nodes should have expected route counts")
// CORRECT: Separate EventuallyWithT for different external call
assert.EventuallyWithT(t, func(c *assert.CollectT) {
status, err := client.Status()
assert.NoError(c, err)
for _, peerKey := range status.Peers() {
peerStatus := status.Peer[peerKey]
requirePeerSubnetRoutesWithCollect(c, peerStatus, expectedPrefixes)
}
}, 10*time.Second, 500*time.Millisecond, "client should see expected routes")
```
### Incorrect Patterns to Avoid
```go
// INCORRECT: Blocking operation wrapped in EventuallyWithT
assert.EventuallyWithT(t, func(c *assert.CollectT) {
status, err := client.Status()
assert.NoError(c, err)
// This is a blocking operation - should NOT be in EventuallyWithT!
command := []string{
"tailscale",
"set",
"--advertise-routes=" + expectedRoutes[string(status.Self.ID)],
}
_, _, err = client.Execute(command)
assert.NoError(c, err)
}, 5*time.Second, 200*time.Millisecond, "wrong pattern")
// INCORRECT: Multiple unrelated external calls in same EventuallyWithT
assert.EventuallyWithT(t, func(c *assert.CollectT) {
// First external call
nodes, err := headscale.ListNodes()
assert.NoError(c, err)
assert.Len(c, nodes, 2)
// Second unrelated external call - WRONG!
status, err := client.Status()
assert.NoError(c, err)
assert.NotNil(c, status)
}, 10*time.Second, 500*time.Millisecond, "mixed operations")
```
## Tags-as-Identity Architecture
### Overview
Headscale implements a **tags-as-identity** model where tags and user ownership are mutually exclusive ways to identify nodes. This is a fundamental architectural principle that affects node registration, ownership, ACL evaluation, and API behavior.
### Core Principle: Tags XOR User Ownership
Every node in Headscale is **either** tagged **or** user-owned, never both:
- **Tagged Nodes**: Ownership is defined by tags (e.g., `tag:server`, `tag:database`)
- Tags are set during registration via tagged PreAuthKey
- Tags are immutable after registration (cannot be changed via API)
- May have `UserID` set for "created by" tracking, but ownership is via tags
- Identified by: `node.IsTagged()` returns `true`
- **User-Owned Nodes**: Ownership is defined by user assignment
- Registered via OIDC, web auth, or untagged PreAuthKey
- Node belongs to a specific user's namespace
- No tags (empty tags array)
- Identified by: `node.UserID().Valid() && !node.IsTagged()`
### Critical Implementation Details
#### Node Identification Methods
```go
// Primary methods for determining node ownership
node.IsTagged() // Returns true if node has tags OR AuthKey.Tags
node.HasTag(tag) // Returns true if node has specific tag
node.IsUserOwned() // Returns true if UserID set AND not tagged
// IMPORTANT: UserID can be set on tagged nodes for tracking!
// Always use IsTagged() to determine actual ownership, not just UserID.Valid()
```
#### UserID Field Semantics
**Critical distinction**: `UserID` has different meanings depending on node type:
- **Tagged nodes**: `UserID` is optional "created by" tracking
- Indicates which user created the tagged PreAuthKey
- Does NOT define ownership (tags define ownership)
- Example: User "alice" creates tagged PreAuthKey with `tag:server`, node gets `UserID=alice.ID` + `Tags=["tag:server"]`
- **User-owned nodes**: `UserID` defines ownership
- Required field for non-tagged nodes
- Defines which user namespace the node belongs to
- Example: User "bob" registers via OIDC, node gets `UserID=bob.ID` + `Tags=[]`
#### Mapper Behavior (mapper/tail.go)
The mapper converts internal nodes to Tailscale protocol format, handling the TaggedDevices special user:
```go
// From mapper/tail.go:102-116
User: func() tailcfg.UserID {
// IMPORTANT: Tags-as-identity model
// Tagged nodes ALWAYS use TaggedDevices user, even if UserID is set
if node.IsTagged() {
return tailcfg.UserID(int64(types.TaggedDevices.ID))
}
// User-owned nodes: use the actual user ID
return tailcfg.UserID(int64(node.UserID().Get()))
}()
```
**TaggedDevices constant** (`types.TaggedDevices.ID = 2147455555`): Special user ID for all tagged nodes in MapResponse protocol.
#### Registration Flow
**Tagged Node Registration** (via tagged PreAuthKey):
1. User creates PreAuthKey with tags: `pak.Tags = ["tag:server"]`
2. Node registers with PreAuthKey
3. Node gets: `Tags = ["tag:server"]`, `UserID = user.ID` (optional tracking), `AuthKeyID = pak.ID`
4. `IsTagged()` returns `true` (ownership via tags)
5. MapResponse sends `User = TaggedDevices.ID`
**User-Owned Node Registration** (via OIDC/web/untagged PreAuthKey):
1. User authenticates or uses untagged PreAuthKey
2. Node registers
3. Node gets: `Tags = []`, `UserID = user.ID` (required)
4. `IsTagged()` returns `false` (ownership via user)
5. MapResponse sends `User = user.ID`
#### API Validation (SetTags)
The SetTags gRPC API enforces tags-as-identity rules:
```go
// From grpcv1.go:340-347
// User-owned nodes are nodes with UserID that are NOT tagged
isUserOwned := nodeView.UserID().Valid() && !nodeView.IsTagged()
if isUserOwned && len(request.GetTags()) > 0 {
return error("cannot set tags on user-owned nodes")
}
```
**Key validation rules**:
- ✅ Can call SetTags on tagged nodes (tags already define ownership)
- ❌ Cannot set tags on user-owned nodes (would violate XOR rule)
- ❌ Cannot remove all tags from tagged nodes (would orphan the node)
#### Database Layer (db/node.go)
**Tag storage**: Tags are stored in PostgreSQL ARRAY column and SQLite JSON column:
```sql
-- From schema.sql
tags TEXT[] DEFAULT '{}' NOT NULL, -- PostgreSQL
tags TEXT DEFAULT '[]' NOT NULL, -- SQLite (JSON array)
```
**Validation** (`state/tags.go`):
- `validateNodeOwnership()`: Enforces tags XOR user rule
- `validateAndNormalizeTags()`: Validates tag format (`tag:name`) and uniqueness
#### Policy Layer
**Tag Ownership** (policy/v2/policy.go):
```go
func NodeCanHaveTag(node types.NodeView, tag string) bool {
// Checks if node's IP is in the tagOwnerMap IP set
// This is IP-based authorization, not UserID-based
if ips, ok := pm.tagOwnerMap[Tag(tag)]; ok {
if slices.ContainsFunc(node.IPs(), ips.Contains) {
return true
}
}
return false
}
```
**Important**: Tag authorization is based on IP ranges in ACL, not UserID. Tags define identity, ACL authorizes that identity.
### Testing Tags-as-Identity
**Unit Tests** (`hscontrol/types/node_tags_test.go`):
- `TestNodeIsTagged`: Validates IsTagged() for various scenarios
- `TestNodeOwnershipModel`: Tests tags XOR user ownership
- `TestUserTypedID`: Helper method validation
**API Tests** (`hscontrol/grpcv1_test.go`):
- `TestSetTags_UserXORTags`: Validates rejection of setting tags on user-owned nodes
- `TestSetTags_TaggedNode`: Validates that tagged nodes (even with UserID) are not rejected
**Auth Tests** (`hscontrol/auth_test.go:890-928`):
- Tests node registration with tagged PreAuthKey
- Validates tags are applied during registration
### Common Pitfalls
1. **Don't check only `UserID.Valid()` to determine user ownership**
- ❌ Wrong: `if node.UserID().Valid() { /* user-owned */ }`
- ✅ Correct: `if node.UserID().Valid() && !node.IsTagged() { /* user-owned */ }`
2. **Don't assume tagged nodes never have UserID set**
- Tagged nodes MAY have UserID for "created by" tracking
- Always use `IsTagged()` to determine ownership type
3. **Don't allow setting tags on user-owned nodes**
- This violates the tags XOR user principle
- Use API validation to prevent this
4. **Don't forget TaggedDevices in mapper**
- All tagged nodes MUST use `TaggedDevices.ID` in MapResponse
- User ID is only for actual user-owned nodes
### Migration Considerations
When nodes transition between ownership models:
- **No automatic migration**: Tags-as-identity is set at registration and immutable
- **Re-registration required**: To change from user-owned to tagged (or vice versa), node must be deleted and re-registered
- **UserID persistence**: UserID on tagged nodes is informational and not cleared
### Architecture Benefits
The tags-as-identity model provides:
1. **Clear ownership semantics**: No ambiguity about who/what owns a node
2. **ACL simplicity**: Tag-based access control without user conflicts
3. **API safety**: Validation prevents invalid ownership states
4. **Protocol compatibility**: TaggedDevices special user aligns with Tailscale's model
## Logging Patterns
### Incremental Log Event Building
When building log statements with multiple fields, especially with conditional fields, use the **incremental log event pattern** instead of long single-line chains. This improves readability and allows conditional field addition.
**Pattern:**
```go
// GOOD: Incremental building with conditional fields
logEvent := log.Debug().
Str("node", node.Hostname).
Str("machine_key", node.MachineKey.ShortString()).
Str("node_key", node.NodeKey.ShortString())
if node.User != nil {
logEvent = logEvent.Str("user", node.User.Username())
} else if node.UserID != nil {
logEvent = logEvent.Uint("user_id", *node.UserID)
} else {
logEvent = logEvent.Str("user", "none")
}
logEvent.Msg("Registering node")
```
**Key rules:**
1. **Assign chained calls back to the variable**: `logEvent = logEvent.Str(...)` - zerolog methods return a new event, so you must capture the return value
2. **Use for conditional fields**: When fields depend on runtime conditions, build incrementally
3. **Use for long log lines**: When a log line exceeds ~100 characters, split it for readability
4. **Call `.Msg()` at the end**: The final `.Msg()` or `.Msgf()` sends the log event
**Anti-pattern to avoid:**
```go
// BAD: Long single-line chains are hard to read and can't have conditional fields
log.Debug().Caller().Str("node", node.Hostname).Str("machine_key", node.MachineKey.ShortString()).Str("node_key", node.NodeKey.ShortString()).Str("user", node.User.Username()).Msg("Registering node")
// BAD: Forgetting to assign the return value (field is lost!)
logEvent := log.Debug().Str("node", node.Hostname)
logEvent.Str("user", username) // This field is LOST - not assigned back
logEvent.Msg("message") // Only has "node" field
```
**When to use this pattern:**
- Log statements with 4+ fields
- Any log with conditional fields
- Complex logging in loops or error handling
- When you need to add context incrementally
**Example from codebase** (`hscontrol/db/node.go`):
```go
logEvent := log.Debug().
Str("node", node.Hostname).
Str("machine_key", node.MachineKey.ShortString()).
Str("node_key", node.NodeKey.ShortString())
if node.User != nil {
logEvent = logEvent.Str("user", node.User.Username())
} else if node.UserID != nil {
logEvent = logEvent.Uint("user_id", *node.UserID)
} else {
logEvent = logEvent.Str("user", "none")
}
logEvent.Msg("Registering test node")
```
### Avoiding Log Helper Functions
Prefer the incremental log event pattern over creating helper functions that return multiple logging closures. Helper functions like `logPollFunc` create unnecessary indirection and allocate closures.
**Instead of:**
```go
// AVOID: Helper function returning closures
func logPollFunc(req tailcfg.MapRequest, node *types.Node) (
func(string, ...any), // warnf
func(string, ...any), // infof
func(string, ...any), // tracef
func(error, string, ...any), // errf
) {
return func(msg string, a ...any) {
log.Warn().
Caller().
Bool("omitPeers", req.OmitPeers).
Bool("stream", req.Stream).
Uint64("node.id", node.ID.Uint64()).
Str("node.name", node.Hostname).
Msgf(msg, a...)
},
// ... more closures
}
```
**Prefer:**
```go
// BETTER: Build log events inline with shared context
func (m *mapSession) logTrace(msg string) {
log.Trace().
Caller().
Bool("omitPeers", m.req.OmitPeers).
Bool("stream", m.req.Stream).
Uint64("node.id", m.node.ID.Uint64()).
Str("node.name", m.node.Hostname).
Msg(msg)
}
// Or use incremental building for complex cases
logEvent := log.Trace().
Caller().
Bool("omitPeers", m.req.OmitPeers).
Bool("stream", m.req.Stream).
Uint64("node.id", m.node.ID.Uint64()).
Str("node.name", m.node.Hostname)
if additionalContext {
logEvent = logEvent.Str("extra", value)
}
logEvent.Msg("Operation completed")
```
## Important Notes
- **Dependencies**: Use `nix develop` for consistent toolchain (Go, buf, protobuf tools, linting)
- **Protocol Buffers**: Changes to `proto/` require `make generate` and should be committed separately
- **Code Style**: Enforced via golangci-lint with golines (width 88) and gofumpt formatting
- **Linting**: ALL code must pass `golangci-lint run --new-from-rev=upstream/main --timeout=5m --fix` before commit
- **Database**: Supports both SQLite (development) and PostgreSQL (production/testing)
- **Integration Tests**: Require Docker and can consume significant disk space - use headscale-integration-tester agent
- **Performance**: NodeStore optimizations are critical for scale - be careful with changes to state management
- **Quality Assurance**: Always use appropriate specialized agents for testing and validation tasks
- **Tags-as-Identity**: Tags and user ownership are mutually exclusive - always use `IsTagged()` to determine ownership

================================================
# CHANGELOG
## 0.29.0 (202x-xx-xx)
**Minimum supported Tailscale client version: v1.76.0**
### Tailscale ACL compatibility improvements
Extensive test cases were systematically generated using Tailscale clients and the official SaaS
to understand how the packet filter should be generated. We discovered a few differences, but
overall our implementation was very close.
[#3036](https://github.com/juanfont/headscale/pull/3036)
### SSH check action
SSH rules with `"action": "check"` are now supported. When a client initiates a SSH connection to a node
with a `check` action policy, the user is prompted to authenticate via OIDC or CLI approval before access
is granted.
A new `headscale auth` CLI command group supports the approval flow:
- `headscale auth approve --auth-id <id>` approves a pending authentication request (SSH check or web auth)
- `headscale auth reject --auth-id <id>` rejects a pending authentication request
- `headscale auth register --auth-id <id> --user <user>` registers a node (replaces deprecated `headscale nodes register`)
[#1850](https://github.com/juanfont/headscale/pull/1850)
### BREAKING
- **ACL Policy**: Wildcard (`*`) in ACL sources and destinations now resolves to Tailscale's CGNAT range (`100.64.0.0/10`) and ULA range (`fd7a:115c:a1e0::/48`) instead of all IPs (`0.0.0.0/0` and `::/0`) [#3036](https://github.com/juanfont/headscale/pull/3036)
- This better matches Tailscale's security model where `*` means "any node in the tailnet" rather than "any IP address"
- Policies relying on wildcard to match non-Tailscale IPs will need to use explicit CIDR ranges instead
- **Note**: Users with non-standard IP ranges configured in `prefixes.ipv4` or `prefixes.ipv6` (which is unsupported and produces a warning) will need to explicitly specify their CIDR ranges in ACL rules instead of using `*`
- **ACL Policy**: Validate autogroup:self source restrictions matching Tailscale behavior - tags, hosts, and IPs are rejected as sources for autogroup:self destinations [#3036](https://github.com/juanfont/headscale/pull/3036)
- Policies using tags, hosts, or IP addresses as sources for autogroup:self destinations will now fail validation
- **Upgrade path**: Headscale now enforces a strict version upgrade path [#3083](https://github.com/juanfont/headscale/pull/3083)
- Skipping minor versions (e.g. 0.27 → 0.29) is blocked; upgrade one minor version at a time
- Downgrading to a previous minor version is blocked
- Patch version changes within the same minor are always allowed
- **ACL Policy**: The `proto:icmp` protocol name now only includes ICMPv4 (protocol 1), matching Tailscale behavior [#3036](https://github.com/juanfont/headscale/pull/3036)
- Previously, `proto:icmp` included both ICMPv4 and ICMPv6
- Use `proto:ipv6-icmp` or protocol number `58` explicitly for ICMPv6
- **CLI**: `headscale nodes register` is deprecated in favour of `headscale auth register --auth-id <id> --user <user>` [#1850](https://github.com/juanfont/headscale/pull/1850)
- The old command continues to work but will be removed in a future release
### Changes
- **SSH Policy**: Add support for `localpart:*@<domain>` in SSH rule `users` field, mapping each matching user's email local-part as their OS username [#3091](https://github.com/juanfont/headscale/pull/3091)
- **ACL Policy**: Add ICMP and IPv6-ICMP protocols to default filter rules when no protocol is specified [#3036](https://github.com/juanfont/headscale/pull/3036)
- **ACL Policy**: Fix autogroup:self handling for tagged nodes - tagged nodes no longer incorrectly receive autogroup:self filter rules [#3036](https://github.com/juanfont/headscale/pull/3036)
- **ACL Policy**: Use CIDR format for autogroup:self destination IPs matching Tailscale behavior [#3036](https://github.com/juanfont/headscale/pull/3036)
- **ACL Policy**: Merge filter rules with identical SrcIPs and IPProto matching Tailscale behavior - multiple ACL rules with the same source now produce a single FilterRule with combined DstPorts [#3036](https://github.com/juanfont/headscale/pull/3036)
- Remove deprecated `--namespace` flag from `nodes list`, `nodes register`, and `debug create-node` commands (use `--user` instead) [#3093](https://github.com/juanfont/headscale/pull/3093)

## 0.28.0 (2026-02-04)
**Minimum supported Tailscale client version: v1.74.0**
### Tags as identity
Tags are now implemented following the Tailscale model where tags and user ownership are mutually exclusive. Devices can be either
user-owned (authenticated via web/OIDC) or tagged (authenticated via tagged PreAuthKeys). Tagged devices receive their identity from
tags rather than users, making them suitable for servers and infrastructure. Applying a tag to a device removes user-based
ownership. See the [Tailscale tags documentation](https://tailscale.com/kb/1068/tags) for details on how tags work.
User-owned nodes can now request tags during registration using `--advertise-tags`. Tags are validated against the `tagOwners` policy
and applied at registration time. Tags can be managed via the CLI or API after registration. Tagged nodes can return to user-owned
by re-authenticating with `tailscale up --advertise-tags= --force-reauth`.
A one-time migration will validate and migrate any `RequestTags` (stored in hostinfo) to the tags column. Tags are validated against
your policy's `tagOwners` rules during migration. [#3011](https://github.com/juanfont/headscale/pull/3011)
### Smarter map updates
The map update system has been rewritten to send smaller, partial updates instead of full network maps whenever possible. This reduces bandwidth usage and improves performance, especially for large networks. The system now properly tracks peer
changes and can send removal notifications when nodes are removed due to policy changes.
[#2856](https://github.com/juanfont/headscale/pull/2856) [#2961](https://github.com/juanfont/headscale/pull/2961)
### Pre-authentication key security improvements
Pre-authentication keys now use bcrypt hashing for improved security [#2853](https://github.com/juanfont/headscale/pull/2853). Keys
are stored as a prefix and bcrypt hash instead of plaintext. The full key is only displayed once at creation time. When listing keys,
only the prefix is shown (e.g., `hskey-auth-{prefix}-***`). All new keys use the format `hskey-auth-{prefix}-{secret}`. Legacy plaintext keys in the format `{secret}` will continue to work for backwards compatibility.
### Web registration templates redesign
The OIDC callback and device registration web pages have been updated to use the Material for MkDocs design system from the official
documentation. The templates now use consistent typography, spacing, and colours across all registration flows.
### Database migration support removed for pre-0.25.0 databases
Headscale no longer supports direct upgrades from databases created before version 0.25.0. Users on older versions must upgrade
sequentially through each stable release, selecting the latest patch version available for each minor release.
### BREAKING
- **API**: The Node message in the gRPC/REST API has been simplified - the `ForcedTags`, `InvalidTags`, and `ValidTags` fields have been removed and replaced with a single `Tags` field that contains the node's applied tags [#2993](https://github.com/juanfont/headscale/pull/2993)
- API clients should use the `Tags` field instead of `ValidTags`
- The `headscale nodes list` CLI command now always shows a Tags column and the `--tags` flag has been removed
- **PreAuthKey CLI**: Commands now use ID-based operations instead of user+key combinations [#2992](https://github.com/juanfont/headscale/pull/2992)
- `headscale preauthkeys create` no longer requires `--user` flag (optional for tracking creation)
- `headscale preauthkeys list` lists all keys (no longer filtered by user)
- `headscale preauthkeys expire --id <ID>` replaces `--user <USER> <KEY>`
- `headscale preauthkeys delete --id <ID>` replaces `--user <USER> <KEY>`
**Before:**
```bash
headscale preauthkeys create --user 1 --reusable --tags tag:server
headscale preauthkeys list --user 1
headscale preauthkeys expire --user 1 <KEY>
headscale preauthkeys delete --user 1 <KEY>
```
**After:**
```bash
headscale preauthkeys create --reusable --tags tag:server
headscale preauthkeys list
headscale preauthkeys expire --id 123
headscale preauthkeys delete --id 123
```
- **Tags**: The gRPC `SetTags` endpoint now allows converting user-owned nodes to tagged nodes by setting tags. [#2885](https://github.com/juanfont/headscale/pull/2885)
- **Tags**: Tags are now resolved from the node's stored Tags field only [#2931](https://github.com/juanfont/headscale/pull/2931)
- `--advertise-tags` is processed during registration, not on every policy evaluation
- PreAuthKey tagged devices ignore `--advertise-tags` from clients
- User-owned nodes can use `--advertise-tags` if authorized by `tagOwners` policy
- Tags can be managed via CLI (`headscale nodes tag`) or the SetTags API after registration
- Database migration support removed for pre-0.25.0 databases [#2883](https://github.com/juanfont/headscale/pull/2883)
- If you are running a version older than 0.25.0, you must upgrade to 0.25.1 first, then upgrade to this release
- See the [upgrade path documentation](https://headscale.net/stable/about/faq/#what-is-the-recommended-update-path-can-i-skip-multiple-versions-while-updating) for detailed guidance
- In version 0.29, all migrations before 0.28.0 will also be removed
- Remove ability to move nodes between users [#2922](https://github.com/juanfont/headscale/pull/2922)
- The `headscale nodes move` CLI command has been removed
- The `MoveNode` API endpoint has been removed
- Nodes are permanently associated with their user or tag at registration time
- Add `oidc.email_verified_required` config option to control email verification requirement [#2860](https://github.com/juanfont/headscale/pull/2860)
- When `true` (default), only verified emails can authenticate via OIDC in conjunction with `oidc.allowed_domains` or
`oidc.allowed_users`. Previous versions allowed to authenticate with an unverified email but did not store the email
address in the user profile. This is now rejected during authentication with an `unverified email` error.
- When `false`, unverified emails are allowed for OIDC authentication and the email address is stored in the user
profile regardless of its verification state.
- **SSH Policy**: Wildcard (`*`) is no longer supported as an SSH destination [#3009](https://github.com/juanfont/headscale/issues/3009)
- Use `autogroup:member` for user-owned devices
- Use `autogroup:tagged` for tagged devices
- Use specific tags (e.g., `tag:server`) for targeted access
**Before:**
```json
{ "action": "accept", "src": ["group:admins"], "dst": ["*"], "users": ["root"] }
```
**After:**
```json
{ "action": "accept", "src": ["group:admins"], "dst": ["autogroup:member", "autogroup:tagged"], "users": ["root"] }
```
- **SSH Policy**: SSH source/destination validation now enforces Tailscale's security model [#3010](https://github.com/juanfont/headscale/issues/3010)
Per [Tailscale SSH documentation](https://tailscale.com/kb/1193/tailscale-ssh), the following rules are now enforced:
1. **Tags cannot SSH to user-owned devices**: SSH rules with `tag:*` or `autogroup:tagged` as source cannot have username destinations (e.g., `alice@`) or `autogroup:member`/`autogroup:self` as destination
2. **Username destinations require same-user source**: If destination is a specific username (e.g., `alice@`), the source must be that exact same user only. Use `autogroup:self` for same-user SSH access instead
**Invalid policies now rejected at load time:**
```json
// INVALID: tag source to user destination
{"src": ["tag:server"], "dst": ["alice@"], ...}
// INVALID: autogroup:tagged to autogroup:member
{"src": ["autogroup:tagged"], "dst": ["autogroup:member"], ...}
// INVALID: group to specific user (use autogroup:self instead)
{"src": ["group:admins"], "dst": ["alice@"], ...}
```
**Valid patterns:**
```json
// Users/groups can SSH to their own devices via autogroup:self
{"src": ["group:admins"], "dst": ["autogroup:self"], ...}
// Users/groups can SSH to tagged devices
{"src": ["group:admins"], "dst": ["autogroup:tagged"], ...}
// Tagged devices can SSH to other tagged devices
{"src": ["autogroup:tagged"], "dst": ["autogroup:tagged"], ...}
// Same user can SSH to their own devices
{"src": ["alice@"], "dst": ["alice@"], ...}
```

## 0.27.0 (2025-10-27)
**Minimum supported Tailscale client version: v1.64.0**
### Database integrity improvements
This release includes a significant database migration that addresses
longstanding issues with the database schema and data integrity that has
accumulated over the years. The migration introduces a `schema.sql` file as the
source of truth for the expected database schema to ensure new migrations that
will cause divergence does not occur again.
These issues arose from a combination of factors discovered over time: SQLite
foreign keys not being enforced for many early versions, all migrations being
run in one large function until version 0.23.0, and inconsistent use of GORM's
AutoMigrate feature. Moving forward, all new migrations will be explicit SQL
operations rather than relying on GORM AutoMigrate, and foreign keys will be
enforced throughout the migration process.
We are only improving SQLite databases with this change - PostgreSQL databases
are not affected.
Please read the
[PR description](https://github.com/juanfont/headscale/pull/2617) for more
technical details about the issues and solutions.
**SQLite Database Backup Example:**
```bash
# Stop headscale
systemctl stop headscale
# Backup sqlite database
cp /var/lib/headscale/db.sqlite /var/lib/headscale/db.sqlite.backup
# Backup sqlite WAL/SHM files (if they exist)
cp /var/lib/headscale/db.sqlite-wal /var/lib/headscale/db.sqlite-wal.backup
cp /var/lib/headscale/db.sqlite-shm /var/lib/headscale/db.sqlite-shm.backup
# Start headscale (migration will run automatically)
systemctl start headscale
```
### DERPMap update frequency
The default DERPMap update frequency has been changed from 24 hours to 3 hours.
If you set the `derp.update_frequency` configuration option, it is recommended
to change it to `3h` to ensure that the headscale instance gets the latest
DERPMap updates when upstream is changed.
### Autogroups
This release adds support for the three missing autogroups: `self`
(experimental), `member`, and `tagged`. Please refer to the
[documentation](https://tailscale.com/kb/1018/autogroups/) for a detailed
explanation.
`autogroup:self` is marked as experimental and should be used with caution, but
we need help testing it. Experimental here means two things; first, generating
the packet filter from policies that use `autogroup:self` is very expensive, and
it might perform, or straight up not work on Headscale installations with a
large number of nodes. Second, the implementation might have bugs or edge cases
we are not aware of, meaning that nodes or users might gain _more_ access than
expected. Please report bugs.
### Node store (in memory database)
Under the hood, we have added a new datastructure to store nodes in memory. This
datastructure is called `NodeStore` and aims to reduce the reading and writing
of nodes to the database layer. We have not benchmarked it, but expect it to
improve performance for read heavy workloads. We think of it as, "worst case" we
have moved the bottle neck somewhere else, and "best case" we should see a good
improvement in compute resource usage at the expense of memory usage. We are
quite excited for this change and think it will make it easier for us to improve
the code base over time and make it more correct and efficient.
### BREAKING
- Remove support for 32-bit binaries [#2692](https://github.com/juanfont/headscale/pull/2692)
- Policy: Zero or empty destination port is no longer allowed [#2606](https://github.com/juanfont/headscale/pull/2606)
- Stricter hostname validation [#2383](https://github.com/juanfont/headscale/pull/2383)
- Hostnames must be valid DNS labels (2-63 characters, alphanumeric and
hyphens only, cannot start/end with hyphen)
- **Client Registration (New Nodes)**: Invalid hostnames are automatically
renamed to `invalid-XXXXXX` format
- `my-laptop` → accepted as-is
- `My-Laptop` → `my-laptop` (lowercased)
- `my_laptop` → `invalid-a1b2c3` (underscore not allowed)
- `test@host` → `invalid-d4e5f6` (@ not allowed)
- `laptop-🚀` → `invalid-j1k2l3` (emoji not allowed)
- **Hostinfo Updates / CLI**: Invalid hostnames are rejected with an error
- Valid names are accepted or lowercased
- Names with invalid characters, too short (<2), too long (>63), or
starting/ending with hyphen are rejected

## 0.26.0 (2025-05-14)
### BREAKING
#### Routes
Route internals have been rewritten, removing the dedicated route table in the
database. This was done to simplify the codebase, which had grown unnecessarily
complex after the routes were split into separate tables. The overhead of having
to go via the database and keeping the state in sync made the code very hard to
reason about and prone to errors. The majority of the route state is only
relevant when headscale is running, and is now only kept in memory. As part of
this, the CLI and API has been simplified to reflect the changes;
```console
$ headscale nodes list-routes
ID | Hostname | Approved | Available | Serving (Primary)
1 | ts-head-ruqsg8 | | 0.0.0.0/0, ::/0 |
2 | ts-unstable-fq7ob4 | | 0.0.0.0/0, ::/0 |
$ headscale nodes approve-routes --identifier 1 --routes 0.0.0.0/0,::/0
Node updated
$ headscale nodes list-routes
ID | Hostname | Approved | Available | Serving (Primary)
1 | ts-head-ruqsg8 | 0.0.0.0/0, ::/0 | 0.0.0.0/0, ::/0 | 0.0.0.0/0, ::/0
2 | ts-unstable-fq7ob4 | | 0.0.0.0/0, ::/0 |
```
Note that if an exit route is approved (0.0.0.0/0 or ::/0), both IPv4 and IPv6
will be approved.
- Route API and CLI has been removed [#2422](https://github.com/juanfont/headscale/pull/2422)
- Routes are now managed via the Node API [#2422](https://github.com/juanfont/headscale/pull/2422)
- Only routes accessible to the node will be sent to the node [#2561](https://github.com/juanfont/headscale/pull/2561)
#### Policy v2
This release introduces a new policy implementation. The new policy is a
complete rewrite, and it introduces some significant quality and consistency
improvements. In principle, there are not really any new features, but some long
standing bugs should have been resolved, or be easier to fix in the future. The
new policy code passes all of our tests.
**Changes**
- The policy is validated and "resolved" when loading, providing errors for
invalid rules and conditions.
- Previously this was done as a mix between load and runtime (when it was
applied to a node).
- This means that when you convert the first time, what was previously a
policy that loaded, but failed at runtime, will now fail at load time.
- Error messages should be more descriptive and informative.
- There is still work to be here, but it is already improved with "typing"
(e.g. only Users can be put in Groups)
- All users in the policy must contain an `@` character.
- If your user naturally contains and `@`, like an email, this will just work.
- If its based on usernames, or other identifiers not containing an `@`, an
`@` should be appended at the end. For example, if your user is `john`, it
must be written as `john@` in the policy.
<details>
<summary>Migration notes when the policy is stored in the database.</summary>
This section **only** applies if the policy is stored in the database and
Headscale 0.26 doesn't start due to a policy error
(`failed to load ACL policy`).
- Start Headscale 0.26 with the environment variable `HEADSCALE_POLICY_V1=1`
set. You can check that Headscale picked up the environment variable by
observing this message during startup: `Using policy manager version: 1`
- Dump the policy to a file: `headscale policy get > policy.json`
- Edit `policy.json` and migrate to policy V2. Use the command
`headscale policy check --file policy.json` to check for policy errors.
- Load the modified policy: `headscale policy set --file policy.json`
- Restart Headscale **without** the environment variable `HEADSCALE_POLICY_V1`.
Headscale should now print the message `Using policy manager version: 2` and
startup successfully.
</details>
**SSH**
The SSH policy has been reworked to be more consistent with the rest of the
policy. In addition, several inconsistencies between our implementation and
Tailscale's upstream has been closed and this might be a breaking change for
some users. Please refer to the
[upstream documentation](https://tailscale.com/kb/1337/acl-syntax#tailscale-ssh)
for more information on which types are allowed in `src`, `dst` and `users`.
There is one large inconsistency left, we allow `*` as a destination as we
currently do not support `autogroup:self`, `autogroup:member` and
`autogroup:tagged`. The support for `*` will be removed when we have support for
the autogroups.
**Current state**
The new policy is passing all tests, both integration and unit tests. This does
not mean it is perfect, but it is a good start. Corner cases that is currently
working in v1 and not tested might be broken in v2 (and vice versa).
**We do need help testing this code**
#### Other breaking changes
- Disallow `server_url` and `base_domain` to be equal [#2544](https://github.com/juanfont/headscale/pull/2544)
- Return full user in API for pre auth keys instead of string [#2542](https://github.com/juanfont/headscale/pull/2542)
- Pre auth key API/CLI now uses ID over username [#2542](https://github.com/juanfont/headscale/pull/2542)
- A non-empty list of global nameservers needs to be specified via
`dns.nameservers.global` if the configuration option `dns.override_local_dns`
is enabled or is not specified in the configuration file. This aligns with
behaviour of tailscale.com.

## 0.24.0 (2025-01-17)
### Security fix: OIDC changes in Headscale 0.24.0
The following issue _only_ affects Headscale installations which authenticate
with OIDC.
_Headscale v0.23.0 and earlier_ identified OIDC users by the "username" part of
their email address (when `strip_email_domain: true`, the default) or whole
email address (when `strip_email_domain: false`).
Depending on how Headscale and your Identity Provider (IdP) were configured,
only using the `email` claim could allow a malicious user with an IdP account to
take over another Headscale user's account, even when
`strip_email_domain: false`.
This would also cause a user to lose access to their Headscale account if they
changed their email address.
_Headscale v0.24.0_ now identifies OIDC users by the `iss` and `sub` claims.
[These are guaranteed by the OIDC specification to be stable and unique](https://openid.net/specs/openid-connect-core-1_0.html#ClaimStability),
even if a user changes email address. A well-designed IdP will typically set
`sub` to an opaque identifier like a UUID or numeric ID, which has no relation
to the user's name or email address.
Headscale v0.24.0 and later will also automatically update profile fields with
OIDC data on login. This means that users can change those details in your IdP,
and have it populate to Headscale automatically the next time they log in.
However, this may affect the way you reference users in policies.
Headscale v0.23.0 and earlier never recorded the `iss` and `sub` fields, so all
legacy (existing) OIDC accounts _need to be migrated_ to be properly secured.
#### What do I need to do to migrate?
Headscale v0.24.0 has an automatic migration feature, which is enabled by
default (`map_legacy_users: true`). **This will be disabled by default in a
future version of Headscale – any unmigrated users will get new accounts.**
The migration will mostly be done automatically, with one exception. If your
OIDC does not provide an `email_verified` claim, Headscale will ignore the
`email`. This means that either the administrator will have to mark the user
emails as verified, or ensure the users verify their emails. Any unverified
emails will be ignored, meaning that the users will get new accounts instead of
being migrated.
After this exception is ensured, make all users log into Headscale with their
account, and Headscale will automatically update the account record. This will
be transparent to the users.
When all users have logged in, you can disable the automatic migration by
setting `map_legacy_users: false` in your configuration file.
Please note that `map_legacy_users` will be set to `false` by default in v0.25.0
and the migration mechanism will be removed in v0.26.0.
<details>
<summary>What does automatic migration do?</summary>
##### What does automatic migration do?
When automatic migration is enabled (`map_legacy_users: true`), Headscale will
first match an OIDC account to a Headscale account by `iss` and `sub`, and then
fall back to matching OIDC users similarly to how Headscale v0.23.0 did:
- If `strip_email_domain: true` (the default): the Headscale username matches
the "username" part of their email address.
- If `strip_email_domain: false`: the Headscale username matches the _whole_
email address.
On migration, Headscale will change the account's username to their
`preferred_username`. **This could break any ACLs or policies which are
configured to match by username.**
Like with Headscale v0.23.0 and earlier, this migration only works for users who
haven't changed their email address since their last Headscale login.
A _successful_ automated migration should otherwise be transparent to users.
Once a Headscale account has been migrated, it will be _unavailable_ to be
matched by the legacy process. An OIDC login with a matching username, but
_non-matching_ `iss` and `sub` will instead get a _new_ Headscale account.
Because of the way OIDC works, Headscale's automated migration process can
_only_ work when a user tries to log in after the update.
Legacy account migration should have no effect on new installations where all
users have a recorded `sub` and `iss`.
</details>
<details>
<summary>What happens when automatic migration is disabled?</summary>
##### What happens when automatic migration is disabled?
When automatic migration is disabled (`map_legacy_users: false`), Headscale will
only try to match an OIDC account to a Headscale account by `iss` and `sub`.
If there is no match, it will get a _new_ Headscale account – even if there was
a legacy account which _could_ have matched and migrated.
We recommend new Headscale users explicitly disable automatic migration – but it
should otherwise have no effect if every account has a recorded `iss` and `sub`.
When automatic migration is disabled, the `strip_email_domain` setting will have
no effect.
</details>
Special thanks to @micolous for reviewing, proposing and working with us on
these changes.
#### Other OIDC changes
Headscale now uses
[the standard OIDC claims](https://openid.net/specs/openid-connect-core-1_0.html#StandardClaims)
to populate and update user information every time they log in:
| Headscale profile field | OIDC claim | Notes / examples |
| ----------------------- | -------------------- | --------------------------------------------------------------------------------------------------------- |
| email address | `email` | Only used when `"email_verified": true` |
| display name | `name` | eg: `Sam Smith` |
| username | `preferred_username` | Varies depending on IdP and configuration, eg: `ssmith`, `ssmith@idp.example.com`, `\\example.com\ssmith` |
| profile picture | `picture` | URL to a profile picture or avatar |
These should show up nicely in the Tailscale client.
This will also affect the way you
[reference users in policies](https://github.com/juanfont/headscale/pull/2205).

## 0.23.0 (2024-09-18)
This release was intended to be mainly a code reorganisation and refactoring,
significantly improving the maintainability of the codebase. This should allow
us to improve further and make it easier for the maintainers to keep on top of
the project. However, as you all have noticed, it turned out to become a much
larger, much longer release cycle than anticipated. It has ended up to be a
release with a lot of rewrites and changes to the code base and functionality of
Headscale, cleaning up a lot of technical debt and introducing a lot of
improvements. This does come with some breaking changes,
**Please remember to always back up your database between versions**
#### Here is a short summary of the broad topics of changes:
Code has been organised into modules, reducing use of global variables/objects,
isolating concerns and “putting the right things in the logical place”.
The new
[policy](https://github.com/juanfont/headscale/tree/main/hscontrol/policy) and
[mapper](https://github.com/juanfont/headscale/tree/main/hscontrol/mapper)
package, containing the ACL/Policy logic and the logic for creating the data
served to clients (the network “map”) has been rewritten and improved. This
change has allowed us to finish SSH support and add additional tests throughout
the code to ensure correctness.
The
[“poller”, or streaming logic](https://github.com/juanfont/headscale/blob/main/hscontrol/poll.go)
has been rewritten and instead of keeping track of the latest updates, checking
at a fixed interval, it now uses go channels, implemented in our new
[notifier](https://github.com/juanfont/headscale/tree/main/hscontrol/notifier)
package and it allows us to send updates to connected clients immediately. This
should both improve performance and potential latency before a client picks up
an update.
Headscale now supports sending “delta” updates, thanks to the new mapper and
poller logic, allowing us to only inform nodes about new nodes, changed nodes
and removed nodes. Previously we sent the entire state of the network every time
an update was due.
While we have a pretty good
[test harness](https://github.com/search?q=repo%3Ajuanfont%2Fheadscale+path%3A_test.go&type=code)
for validating our changes, the changes came down to
[284 changed files with 32,316 additions and 24,245 deletions](https://github.com/juanfont/headscale/compare/b01f1f1867136d9b2d7b1392776eb363b482c525...ed78ecd)
and bugs are expected. We need help testing this release. In addition, while we
think the performance should in general be better, there might be regressions in
parts of the platform, particularly where we prioritised correctness over speed.
There are also several bugfixes that has been encountered and fixed as part of
implementing these changes, particularly after improving the test harness as
part of adopting [#1460](https://github.com/juanfont/headscale/pull/1460).
### BREAKING
- Code reorganisation, a lot of code has moved, please review the following PRs
accordingly [#1473](https://github.com/juanfont/headscale/pull/1473)
- Change the structure of database configuration, see
[config-example.yaml](./config-example.yaml) for the new structure.
[#1700](https://github.com/juanfont/headscale/pull/1700)
- Old structure has been remove and the configuration _must_ be converted.
- Adds additional configuration for PostgreSQL for setting max open, idle
connection and idle connection lifetime.
- API: Machine is now Node [#1553](https://github.com/juanfont/headscale/pull/1553)
- Remove support for older Tailscale clients [#1611](https://github.com/juanfont/headscale/pull/1611)
- The oldest supported client is 1.42
- Headscale checks that _at least_ one DERP is defined at start [#1564](https://github.com/juanfont/headscale/pull/1564)
- If no DERP is configured, the server will fail to start, this can be because
it cannot load the DERPMap from file or url.
- Embedded DERP server requires a private key [#1611](https://github.com/juanfont/headscale/pull/1611)
- Add a filepath entry to
[`derp.server.private_key_path`](https://github.com/juanfont/headscale/blob/b35993981297e18393706b2c963d6db882bba6aa/config-example.yaml#L95)
- Docker images are now built with goreleaser (ko) [#1716](https://github.com/juanfont/headscale/pull/1716)
[#1763](https://github.com/juanfont/headscale/pull/1763)
- Entrypoint of container image has changed from shell to headscale, require
change from `headscale serve` to `serve`
- `/var/lib/headscale` and `/var/run/headscale` is no longer created
automatically, see [container docs](./docs/setup/install/container.md)
- Prefixes are now defined per v4 and v6 range. [#1756](https://github.com/juanfont/headscale/pull/1756)
- `ip_prefixes` option is now `prefixes.v4` and `prefixes.v6`
- `prefixes.allocation` can be set to assign IPs at `sequential` or `random`.
[#1869](https://github.com/juanfont/headscale/pull/1869)
- MagicDNS domains no longer contain usernames []()
- This is in preparation to fix Headscales implementation of tags which
currently does not correctly remove the link between a tagged device and a
user. As tagged devices will not have a user, this will require a change to
the DNS generation, removing the username, see
[#1369](https://github.com/juanfont/headscale/issues/1369) for more
information.
- `use_username_in_magic_dns` can be used to turn this behaviour on again, but
note that this option _will be removed_ when tags are fixed.
- dns.base_domain can no longer be the same as (or part of) server_url.
- This option brings Headscales behaviour in line with Tailscale.
- YAML files are no longer supported for headscale policy. [#1792](https://github.com/juanfont/headscale/pull/1792)
- HuJSON is now the only supported format for policy.
- DNS configuration has been restructured [#2034](https://github.com/juanfont/headscale/pull/2034)
- Please review the new [config-example.yaml](./config-example.yaml) for the
new structure.

renamed to `level` [#768](https://github.com/juanfont/headscale/pull/768)
- Removed Alpine Linux container image [#962](https://github.com/juanfont/headscale/pull/962)
### Important Changes
- Added support for Tailscale TS2021 protocol [#738](https://github.com/juanfont/headscale/pull/738)
- Add experimental support for
[SSH ACL](https://tailscale.com/kb/1018/acls/#tailscale-ssh) (see docs for
limitations) [#847](https://github.com/juanfont/headscale/pull/847)
- Please note that this support should be considered _partially_ implemented
- SSH ACLs status:
- Support `accept` and `check` (SSH can be enabled and used for connecting
and authentication)
- Rejecting connections **are not supported**, meaning that if you enable
SSH, then assume that _all_ `ssh` connections **will be allowed**.
- If you decided to try this feature, please carefully managed permissions
by blocking port `22` with regular ACLs or do _not_ set `--ssh` on your
clients.
- We are currently improving our testing of the SSH ACLs, help us get an
overview by testing and giving feedback.
- This feature should be considered dangerous and it is disabled by default.
Enable by setting `HEADSCALE_EXPERIMENTAL_FEATURE_SSH=1`.

## 0.14.0 (2022-02-24)
**UPCOMING ### BREAKING From the **next\*\* version (`0.15.0`), all machines
will be able to communicate regardless of if they are in the same namespace.
This means that the behaviour currently limited to ACLs will become default.

FILE: CONTRIBUTING.md
================================================
# Contributing
Headscale is "Open Source, acknowledged contribution", this means that any contribution will have to be discussed with the maintainers before being added to the project.
This model has been chosen to reduce the risk of burnout by limiting the maintenance overhead of reviewing and validating third-party code.
## Why do we have this model?
Headscale has a small maintainer team that tries to balance working on the project, fixing bugs and reviewing contributions.
When we work on issues ourselves, we develop first hand knowledge of the code and it makes it possible for us to maintain and own the code as the project develops.
Code contributions are seen as a positive thing. People enjoy and engage with our project, but it also comes with some challenges; we have to understand the code, we have to understand the feature, we might have to become familiar with external libraries or services and we think about security implications. All those steps are required during the reviewing process. After the code has been merged, the feature has to be maintained. Any changes reliant on external services must be updated and expanded accordingly.
The review and day-1 maintenance adds a significant burden on the maintainers. Often we hope that the contributor will help out, but we found that most of the time, they disappear after their new feature was added.
This means that when someone contributes, we are mostly happy about it, but we do have to run it through a series of checks to establish if we actually can maintain this feature.
## What do we require?
A general description is provided here and an explicit list is provided in our pull request template.
All new features have to start out with a design document, which should be discussed on the issue tracker (not discord). It should include a use case for the feature, how it can be implemented, who will implement it and a plan for maintaining it.
All features have to be end-to-end tested (integration tests) and have good unit test coverage to ensure that they work as expected. This will also ensure that the feature continues to work as expected over time. If a change cannot be tested, a strong case for why this is not possible needs to be presented.
The contributor should help to maintain the feature over time. In case the feature is not maintained probably, the maintainers reserve themselves the right to remove features they redeem as unmaintainable. This should help to improve the quality of the software and keep it in a maintainable state.
## Bug fixes
Headscale is open to code contributions for bug fixes without discussion.
## Documentation
If you find mistakes in the documentation, please submit a fix to the documentation.

An open source, self-hosted implementation of the Tailscale control server.
Join our [Discord server](https://discord.gg/c84AZQhmpx) for a chat.
**Note:** Always select the same GitHub tag as the released version you use
to ensure you have the correct example configuration. The `main` branch might
contain unreleased changes. The documentation is available for stable and
development versions:
- [Documentation for the stable version](https://headscale.net/stable/)
- [Documentation for the development version](https://headscale.net/development/)
## What is Tailscale
Tailscale is [a modern VPN](https://tailscale.com/) built on top of
[Wireguard](https://www.wireguard.com/).
It [works like an overlay network](https://tailscale.com/blog/how-tailscale-works/)
between the computers of your networks - using
[NAT traversal](https://tailscale.com/blog/how-nat-traversal-works/).
Everything in Tailscale is Open Source, except the GUI clients for proprietary OS
(Windows and macOS/iOS), and the control server.
The control server works as an exchange point of Wireguard public keys for the
nodes in the Tailscale network. It assigns the IP addresses of the clients,
creates the boundaries between each user, enables sharing machines between users,
and exposes the advertised routes of your nodes.
A [Tailscale network (tailnet)](https://tailscale.com/kb/1136/tailnet/) is private
network which Tailscale assigns to a user in terms of private users or an
organisation.
## Design goal
Headscale aims to implement a self-hosted, open source alternative to the
[Tailscale](https://tailscale.com/) control server. Headscale's goal is to
provide self-hosters and hobbyists with an open-source server they can use for
their projects and labs. It implements a narrow scope, a _single_ Tailscale
network (tailnet), suitable for a personal use, or a small open-source
organisation.
## Supporting Headscale
If you like `headscale` and find it useful, there is a sponsorship and donation
buttons available in the repo.
## Features
Please see ["Features" in the documentation](https://headscale.net/stable/about/features/).
## Client OS support
Please see ["Client and operating system support" in the documentation](https://headscale.net/stable/about/clients/).
## Running headscale
**Please note that we do not support nor encourage the use of reverse proxies
and container to run Headscale.**
Please have a look at the [`documentation`](https://headscale.net/stable/).
For NixOS users, a module is available in [`nix/`](./nix/).
## Talks
- Fosdem 2026 (video): [Headscale & Tailscale: The complementary open source clone](https://fosdem.org/2026/schedule/event/KYQ3LL-headscale-the-complementary-open-source-clone/)
- presented by Kristoffer Dalby
- Fosdem 2023 (video): [Headscale: How we are using integration testing to reimplement Tailscale](https://fosdem.org/2023/schedule/event/goheadscale/)
- presented by Juan Font Alonso and Kristoffer Dalby
## Disclaimer
This project is not associated with Tailscale Inc.
However, one of the active maintainers for Headscale [is employed by Tailscale](https://tailscale.com/blog/opensource) and he is allowed to spend work hours contributing to the project. Contributions from this maintainer are reviewed by other maintainers.
The maintainers work together on setting the direction for the project. The underlying principle is to serve the community of self-hosters, enthusiasts and hobbyists - while having a sustainable project.
## Contributing
Please read the [CONTRIBUTING.md](./CONTRIBUTING.md) file.
### Requirements
To contribute to headscale you would need the latest version of [Go](https://golang.org)
and [Buf](https://buf.build) (Protobuf generator).
We recommend using [Nix](https://nixos.org/) to setup a development environment. This can
be done with `nix develop`, which will install the tools and give you a shell.
This guarantees that you will have the same dev env as `headscale` maintainers.
### Code style
To ensure we have some consistency with a growing number of contributions,
this project has adopted linting and style/formatting rules:
The **Go** code is linted with [`golangci-lint`](https://golangci-lint.run) and
formatted with [`golines`](https://github.com/segmentio/golines) (width 88) and
[`gofumpt`](https://github.com/mvdan/gofumpt).
Please configure your editor to run the tools while developing and make sure to
run `make lint` and `make fmt` before committing any code.
The **Proto** code is linted with [`buf`](https://docs.buf.build/lint/overview) and
formatted with [`clang-format`](https://clang.llvm.org/docs/ClangFormat.html).
The **docs** are formatted with [`mdformat`](https://mdformat.readthedocs.io).
The **rest** (Markdown, YAML, etc) is formatted with [`prettier`](https://prettier.io).
Check out the `.golangci.yaml` and `Makefile` to see the specific configuration.
### Install development tools
- Go
- Buf
- Protobuf tools
Install and activate:
```shell
nix develop
```
### Testing and building
Some parts of the project require the generation of Go code from Protobuf
(if changes are made in `proto/`) and it must be (re-)generated with:
```shell
make generate
```
**Note**: Please check in changes from `gen/` in a separate commit to make it easier to review.
To run the tests:
```shell
make test
```
To build the program:
```shell
make build
```
### Development workflow
We recommend using Nix for dependency management to ensure you have all required tools. If you prefer to manage dependencies yourself, you can use Make directly:
**With Nix (recommended):**
```shell
nix develop
make test
make build
```
**With your own dependencies:**
```shell
make test
make build
```
The Makefile will warn you if any required tools are missing and suggest running `nix develop`. Run `make help` to see all available targets.

# Frequently Asked Questions
## What is the design goal of headscale?
Headscale aims to implement a self-hosted, open source alternative to the
[Tailscale](https://tailscale.com/) control server. Headscale's goal is to
provide self-hosters and hobbyists with an open-source server they can use for
their projects and labs. It implements a narrow scope, a _single_ Tailscale
network (tailnet), suitable for a personal use, or a small open-source
organisation.
## How can I contribute?
Headscale is "Open Source, acknowledged contribution", this means that any
contribution will have to be discussed with the Maintainers before being submitted.
Please see [Contributing](contributing.md) for more information.
## Why is 'acknowledged contribution' the chosen model?
Both maintainers have full-time jobs and families, and we want to avoid burnout. We also want to avoid frustration from contributors when their PRs are not accepted.
We are more than happy to exchange emails, or to have dedicated calls before a PR is submitted.
## When/Why is Feature X going to be implemented?
We use [GitHub Milestones to plan for upcoming Headscale releases](https://github.com/juanfont/headscale/milestones).
Have a look at [our current plan](https://github.com/juanfont/headscale/milestones) to get an idea when a specific
feature is about to be implemented. The release plan is subject to change at any time.
If you're interested in contributing, please post a feature request about it. Please be aware that there are a number of
reasons why we might not accept specific contributions:
- It is not possible to implement the feature in a way that makes sense in a self-hosted environment.
- Given that we are reverse-engineering Tailscale to satisfy our own curiosity, we might be interested in implementing the feature ourselves.
- You are not sending unit and integration tests with it.
## Do you support Y method of deploying headscale?
We currently support deploying headscale using our binaries and the DEB packages. Visit our [installation guide using
official releases](../setup/install/official.md) for more information.
In addition to that, you may use packages provided by the community or from distributions. Learn more in the
[installation guide using community packages](../setup/install/community.md).
For convenience, we also [build container images with headscale](../setup/install/container.md). But **please be aware that
we don't officially support deploying headscale using Docker**. On our [Discord server](https://discord.gg/c84AZQhmpx)
we have a "docker-issues" channel where you can ask for Docker-specific help to the community.
## What is the recommended update path? Can I skip multiple versions while updating?
Please follow the steps outlined in the [upgrade guide](../setup/upgrade.md) to update your existing Headscale
installation. Its required to update from one stable version to the next (e.g. 0.26.0 → 0.27.1 → 0.28.0) without
skipping minor versions in between. You should always pick the latest available patch release.
Be sure to check the [changelog](https://github.com/juanfont/headscale/blob/main/CHANGELOG.md) for version specific
upgrade instructions and breaking changes.
## Scaling / How many clients does Headscale support?
It depends. As often stated, Headscale is not enterprise software and our focus
is homelabbers and self-hosters. Of course, we do not prevent people from using
it in a commercial/professional setting and often get questions about scaling.
Please note that when Headscale is developed, performance is not part of the
consideration as the main audience is considered to be users with a modest
amount of devices. We focus on correctness and feature parity with Tailscale
SaaS over time.
To understand if you might be able to use Headscale for your use case, I will
describe two scenarios in an effort to explain what is the central bottleneck
of Headscale:
1. An environment with 1000 servers
- they rarely "move" (change their endpoints)
- new nodes are added rarely
1. An environment with 80 laptops/phones (end user devices)
- nodes move often, e.g. switching from home to office
Headscale calculates a map of all nodes that need to talk to each other,
creating this "world map" requires a lot of CPU time. When an event that
requires changes to this map happens, the whole "world" is recalculated, and a
new "world map" is created for every node in the network.
This means that under certain conditions, Headscale can likely handle 100s
of devices (maybe more), if there is _little to no change_ happening in the
network. For example, in Scenario 1, the process of computing the world map is
extremely demanding due to the size of the network, but when the map has been
created and the nodes are not changing, the Headscale instance will likely
return to a very low resource usage until the next time there is an event
requiring the new map.
In the case of Scenario 2, the process of computing the world map is less
demanding due to the smaller size of the network, however, the type of nodes
will likely change frequently, which would lead to a constant resource usage.
Headscale will start to struggle when the two scenarios overlap, e.g. many nodes
with frequent changes will cause the resource usage to remain constantly high.
In the worst case scenario, the queue of nodes waiting for their map will grow
to a point where Headscale never will be able to catch up, and nodes will never
learn about the current state of the world.
We expect that the performance will improve over time as we improve the code
base, but it is not a focus. In general, we will never make the tradeoff to make
things faster on the cost of less maintainable or readable code. We are a small
team and have to optimise for maintainability.
## Which database should I use?
We recommend the use of SQLite as database for headscale:
- SQLite is simple to setup and easy to use
- It scales well for all of headscale's use cases
- Development and testing happens primarily on SQLite
- PostgreSQL is still supported, but is considered to be in "maintenance mode"
The headscale project itself does not provide a tool to migrate from PostgreSQL to SQLite. Please have a look at [the
related tools documentation](../ref/integration/tools.md) for migration tooling provided by the community.
The choice of database has little to no impact on the performance of the server,
see [Scaling / How many clients does Headscale support?](#scaling-how-many-clients-does-headscale-support) for understanding how Headscale spends its resources.
## Why is my reverse proxy not working with headscale?
We don't know. We don't use reverse proxies with headscale ourselves, so we don't have any experience with them. We have
[community documentation](../ref/integration/reverse-proxy.md) on how to configure various reverse proxies, and a
dedicated "reverse-proxy-issues" channel on our [Discord server](https://discord.gg/c84AZQhmpx) where you can ask for
help to the community.
## Can I use headscale and tailscale on the same machine?
Running headscale on a machine that is also in the tailnet can cause problems with subnet routers, traffic relay nodes, and MagicDNS. It might work, but it is not supported.
## Why do two nodes see each other in their status, even if an ACL allows traffic only in one direction?
A frequent use case is to allow traffic only from one node to another, but not the other way around. For example, the
workstation of an administrator should be able to connect to all nodes but the nodes themselves shouldn't be able to
connect back to the administrator's node. Why do all nodes see the administrator's workstation in the output of
`tailscale status`?
This is essentially how Tailscale works. If traffic is allowed to flow in one direction, then both nodes see each other
in their output of `tailscale status`. Traffic is still filtered according to the ACL, with the exception of
`tailscale ping` which is always allowed in either direction.
See also <https://tailscale.com/kb/1087/device-visibility>.
## My policy is stored in the database and Headscale refuses to start due to an invalid policy. How can I recover?
Headscale checks if the policy is valid during startup and refuses to start if it detects an error. The error message
indicates which part of the policy is invalid. Follow these steps to fix your policy:
- Dump the policy to a file: `headscale policy get --bypass-grpc-and-access-database-directly > policy.json`
- Edit and fixup `policy.json`. Use the command `headscale policy check --file policy.json` to validate the policy.
- Load the modified policy: `headscale policy set --bypass-grpc-and-access-database-directly --file policy.json`
- Start Headscale as usual.
!!! warning "Full server configuration required"
The above commands to get/set the policy require a complete server configuration file including database settings. A
minimal config to [control Headscale via remote CLI](../ref/api.md#grpc) is not sufficient. You may use
`headscale -c /path/to/config.yaml` to specify the path to an alternative configuration file.
## How can I migrate back to the recommended IP prefixes?
Tailscale only supports the IP prefixes `100.64.0.0/10` and `fd7a:115c:a1e0::/48` or smaller subnets thereof. The
following steps can be used to migrate from unsupported IP prefixes back to the supported and recommended ones.
!!! warning "Backup and test in a demo environment required"
The commands below update the IP addresses of all nodes in your tailnet and this might have a severe impact in your
specific environment. At a minimum:
- [Create a backup of your database](../setup/upgrade.md#backup)
- Test the commands below in a representive demo environment. This allows to catch subsequent connectivity errors
early and see how the tailnet behaves in your specific environment.
- Stop Headscale
- Restore the default prefixes in the [configuration file](../ref/configuration.md):
```yaml
prefixes:
v4: 100.64.0.0/10
v6: fd7a:115c:a1e0::/48
```
- Update the `nodes.ipv4` and `nodes.ipv6` columns in the database and assign each node a unique IPv4 and IPv6 address.
The following SQL statement assigns IP addresses based on the node ID:
```sql
UPDATE nodes
SET ipv4=concat('100.64.', id/256, '.', id%256),
ipv6=concat('fd7a:115c:a1e0::', format('%x', id));
```
- Update the [policy](../ref/acls.md) to reflect the IP address changes (if any)
- Start Headscale
Nodes should reconnect within a few seconds and pickup their newly assigned IP addresses.
## How can I avoid to send logs to Tailscale Inc?
A Tailscale client [collects logs about its operation and connection attempts with other
clients](https://tailscale.com/kb/1011/log-mesh-traffic#client-logs) and sends them to a central log service operated by
Tailscale Inc.
Headscale, by default, instructs clients to disable log submission to the central log service. This configuration is
applied by a client once it successfully connected with Headscale. See the configuration option `logtail.enabled` in the
[configuration file](../ref/configuration.md) for details.
Alternatively, logging can also be disabled on the client side. This is independent of Headscale and opting out of
client logging disables log submission early during client startup. The configuration is operating system specific and
is usually achieved by setting the environment variable `TS_NO_LOGS_NO_SUPPORT=true` or by passing the flag
`--no-logs-no-support` to `tailscaled`. See
<https://tailscale.com/kb/1011/log-mesh-traffic#opting-out-of-client-logging> for details.

# Welcome to headscale
Headscale is an open source, self-hosted implementation of the Tailscale control server.
This page contains the documentation for the latest version of headscale. Please also check our [FAQ](./about/faq.md).
Join our [Discord server](https://discord.gg/c84AZQhmpx) for a chat and community support.
## Design goal
Headscale aims to implement a self-hosted, open source alternative to the
[Tailscale](https://tailscale.com/) control server. Headscale's goal is to
provide self-hosters and hobbyists with an open-source server they can use for
their projects and labs. It implements a narrow scope, a _single_ Tailscale
network (tailnet), suitable for a personal use, or a small open-source
organisation.
## Supporting headscale
Please see [Sponsor](about/sponsor.md) for more information.
## Contributing
Headscale is "Open Source, acknowledged contribution", this means that any
contribution will have to be discussed with the Maintainers before being submitted.
Please see [Contributing](about/contributing.md) for more information.
## About
Headscale is maintained by [Kristoffer Dalby](https://kradalby.no/) and [Juan Font](https://font.eu).
================================================
FILE: docs/ref/acls.md
================================================
Headscale implements the same policy ACLs as Tailscale.com, adapted to the self-hosted environment.
For instance, instead of referring to users when defining groups you must
use users (which are the equivalent to user/logins in Tailscale.com).
Please check https://tailscale.com/kb/1018/acls/ for further information.
When using ACL's the User borders are no longer applied. All machines
whichever the User have the ability to communicate with other hosts as
long as the ACL's permits this exchange.
## ACL Setup
To enable and configure ACLs in Headscale, you need to specify the path to your ACL policy file in the `policy.path` key in `config.yaml`.
Your ACL policy file must be formatted using [huJSON](https://github.com/tailscale/hujson).
Info on how these policies are written can be found
[here](https://tailscale.com/kb/1018/acls/).
Please reload or restart Headscale after updating the ACL file. Headscale may be reloaded either via its systemd service
(`sudo systemctl reload headscale`) or by sending a SIGHUP signal (`sudo kill -HUP $(pidof headscale)`) to the main
process. Headscale logs the result of ACL policy processing after each reload.
## Simple Examples
- [**Allow All**](https://tailscale.com/kb/1192/acl-samples#allow-all-default-acl): If you define an ACL file but completely omit the `"acls"` field from its content, Headscale will default to an "allow all" policy. This means all devices connected to your tailnet will be able to communicate freely with each other.
```json
{}
```
- [**Deny All**](https://tailscale.com/kb/1192/acl-samples#deny-all): To prevent all communication within your tailnet, you can include an empty array for the `"acls"` field in your policy file.
```json
{
"acls": []
}
```
## Complex Example
Let's build a more complex example use case for a small business (It may be the place where
ACL's are the most useful).
We have a small company with a boss, an admin, two developers and an intern.
The boss should have access to all servers but not to the user's hosts. Admin
should also have access to all hosts except that their permissions should be
limited to maintaining the hosts (for example purposes). The developers can do
anything they want on dev hosts but only watch on productions hosts. Intern
can only interact with the development servers.
There's an additional server that acts as a router, connecting the VPN users
to an internal network `10.20.0.0/16`. Developers must have access to those
internal resources.
Each user have at least a device connected to the network and we have some
servers.
- database.prod
- database.dev
- app-server1.prod
- app-server1.dev
- billing.internal
- router.internal
When [registering the servers](../usage/getting-started.md#register-a-node) we
will need to add the flag `--advertise-tags=tag:<tag1>,tag:<tag2>`, and the user
that is registering the server should be allowed to do it. Since anyone can add
tags to a server they can register, the check of the tags is done on headscale
server and only valid tags are applied. A tag is valid if the user that is
registering it is allowed to do it.
Here are the ACL's to implement the same permissions as above:
```json title="acl.json"
{
// groups are collections of users having a common scope. A user can be in multiple groups
// groups cannot be composed of groups
"groups": {
"group:boss": ["boss@"],
"group:dev": ["dev1@", "dev2@"],
"group:admin": ["admin1@"],
"group:intern": ["intern1@"]
},
// tagOwners in tailscale is an association between a TAG and the people allowed to set this TAG on a server.
// This is documented [here](https://tailscale.com/kb/1068/acl-tags#defining-a-tag)
// and explained [here](https://tailscale.com/blog/rbac-like-it-was-meant-to-be/)
"tagOwners": {
// the administrators can add servers in production
"tag:prod-databases": ["group:admin"],
"tag:prod-app-servers": ["group:admin"],
// the boss can tag any server as internal
"tag:internal": ["group:boss"],
// dev can add servers for dev purposes as well as admins
"tag:dev-databases": ["group:admin", "group:dev"],
"tag:dev-app-servers": ["group:admin", "group:dev"]
// interns cannot add servers
},
// hosts should be defined using its IP addresses and a subnet mask.
// to define a single host, use a /32 mask. You cannot use DNS entries here,
// as they're prone to be hijacked by replacing their IP addresses.
// see https://github.com/tailscale/tailscale/issues/3800 for more information.

{
"action": "accept",
"src": ["autogroup:member"],
"dst": ["autogroup:self:*"]
}
]
}
```
## Autogroups
Headscale supports several autogroups that automatically include users, destinations, or devices with specific properties. Autogroups provide a convenient way to write ACL rules without manually listing individual users or devices.
### `autogroup:internet`
Allows access to the internet through [exit nodes](routes.md#exit-node). Can only be used in ACL destinations.
```json
{
"action": "accept",
"src": ["group:users"],
"dst": ["autogroup:internet:*"]
}
```
### `autogroup:member`
Includes all [personal (untagged) devices](registration.md/#identity-model).
```json
{
"action": "accept",
"src": ["autogroup:member"],
"dst": ["tag:prod-app-servers:80,443"]
}
```
### `autogroup:tagged`
Includes all devices that [have at least one tag](registration.md/#identity-model).
```json
{
"action": "accept",
"src": ["autogroup:tagged"],
"dst": ["tag:monitoring:9090"]
}
```
### `autogroup:self`
!!! warning "The current implementation of `autogroup:self` is inefficient"
Includes devices where the same user is authenticated on both the source and destination. Does not include tagged devices. Can only be used in ACL destinations.
```json
{
"action": "accept",
"src": ["autogroup:member"],
"dst": ["autogroup:self:*"]
}
```
*Using `autogroup:self` may cause performance degradation on the Headscale coordinator server in large deployments, as filter rules must be compiled per-node rather than globally and the current implementation is not very efficient.*
If you experience performance issues, consider using more specific ACL rules or limiting the use of `autogroup:self`.
```json
{
// The following rules allow internal users to communicate with their
// own nodes in case autogroup:self is causing performance issues.
{ "action": "accept", "src": ["boss@"], "dst": ["boss@:*"] },
{ "action": "accept", "src": ["dev1@"], "dst": ["dev1@:*"] },
{ "action": "accept", "src": ["dev2@"], "dst": ["dev2@:*"] },
{ "action": "accept", "src": ["admin1@"], "dst": ["admin1@:*"] },
{ "action": "accept", "src": ["intern1@"], "dst": ["intern1@:*"] }
}
```
### `autogroup:nonroot`
Used in Tailscale SSH rules to allow access to any user except root. Can only be used in the `users` field of SSH rules.
```json
{
"action": "accept",
"src": ["autogroup:member"],
"dst": ["autogroup:self"],
"users": ["autogroup:nonroot"]
}
```

FILE: docs/ref/api.md
================================================
# API
Headscale provides a [HTTP REST API](#rest-api) and a [gRPC interface](#grpc) which may be used to integrate a [web
interface](integration/web-ui.md), [remote control Headscale](#setup-remote-control) or provide a base for custom
integration and tooling.
Both interfaces require a valid API key before use. To create an API key, log into your Headscale server and generate
one with the default expiration of 90 days:
```shell
headscale apikeys create
```
Copy the output of the command and save it for later. Please note that you can not retrieve an API key again. If the API
key is lost, expire the old one, and create a new one.
To list the API keys currently associated with the server:
```shell
headscale apikeys list
```
and to expire an API key:
```shell
headscale apikeys expire --prefix <PREFIX>
```
## REST API
- API endpoint: `/api/v1`, e.g. `https://headscale.example.com/api/v1`
- Documentation: `/swagger`, e.g. `https://headscale.example.com/swagger`
- Headscale Version: `/version`, e.g. `https://headscale.example.com/version`
- Authenticate using HTTP Bearer authentication by sending the [API key](#api) with the HTTP `Authorization: Bearer <API_KEY>` header.
Start by [creating an API key](#api) and test it with the examples below. Read the API documentation provided by your
Headscale server at `/swagger` for details.
=== "Get details for all users"
```console
curl -H "Authorization: Bearer <API_KEY>" \
https://headscale.example.com/api/v1/user
```
=== "Get details for user 'bob'"
```console
curl -H "Authorization: Bearer <API_KEY>" \
https://headscale.example.com/api/v1/user?name=bob
```
=== "Register a node"
```console
curl -H "Authorization: Bearer <API_KEY>" \
--json '{"user": "<USER>", "authId": "AUTH_ID>"}' \
https://headscale.example.com/api/v1/auth/register
```
## gRPC
The gRPC interface can be used to control a Headscale instance from a remote machine with the `headscale` binary.
### Prerequisite
- A workstation to run `headscale` (any supported platform, e.g. Linux).
- A Headscale server with gRPC enabled.
- Connections to the gRPC port (default: `50443`) are allowed.
- Remote access requires an encrypted connection via TLS.
- An [API key](#api) to authenticate with the Headscale server.
### Setup remote control
1. Download the [`headscale` binary from GitHub's release page](https://github.com/juanfont/headscale/releases). Make
sure to use the same version as on the server.
1. Put the binary somewhere in your `PATH`, e.g. `/usr/local/bin/headscale`
1. Make `headscale` executable: `chmod +x /usr/local/bin/headscale`
1. [Create an API key](#api) on the Headscale server.
1. Provide the connection parameters for the remote Headscale server either via a minimal YAML configuration file or
via environment variables:
=== "Minimal YAML configuration file"
```yaml title="config.yaml"
cli:
address: <HEADSCALE_ADDRESS>:<PORT>
api_key: <API_KEY>
```
=== "Environment variables"
```shell
export HEADSCALE_CLI_ADDRESS="<HEADSCALE_ADDRESS>:<PORT>"
export HEADSCALE_CLI_API_KEY="<API_KEY>"
```
This instructs the `headscale` binary to connect to a remote instance at `<HEADSCALE_ADDRESS>:<PORT>`, instead of
connecting to the local instance.
1. Test the connection by listing all nodes:
```shell
headscale nodes list
```
You should now be able to see a list of your nodes from your workstation, and you can
now control the Headscale server from your workstation.
### Behind a proxy
It's possible to run the gRPC remote endpoint behind a reverse proxy, like Nginx, and have it run on the _same_ port as Headscale.
While this is _not a supported_ feature, an example on how this can be set up on
[NixOS is shown here](https://github.com/kradalby/dotfiles/blob/4489cdbb19cddfbfae82cd70448a38fde5a76711/machines/headscale.oracldn/headscale.nix#L61-L91).
### Troubleshooting
- Make sure you have the _same_ Headscale version on your server and workstation.
- Ensure that connections to the gRPC port are allowed.
- Verify that your TLS certificate is valid and trusted.
- If you don't have access to a trusted certificate (e.g. from Let's Encrypt), either:
- Add your self-signed certificate to the trust store of your OS _or_
- Disable certificate verification by either setting `cli.insecure: true` in the configuration file or by setting
`HEADSCALE_CLI_INSECURE=1` via an environment variable. We do **not** recommend to disable certificate validation.
================================================
FILE: docs/ref/configuration.md
================================================
# Configuration
- Headscale loads its configuration from a YAML file
- It searches for `config.yaml` in the following paths:
- `/etc/headscale`
- `$HOME/.headscale`
- the current working directory
- To load the configuration from a different path, use:
- the command line flag `-c`, `--config`
- the environment variable `HEADSCALE_CONFIG`
- Validate the configuration file with: `headscale configtest`
!!! example "Get the [example configuration from the GitHub repository](https://github.com/juanfont/headscale/blob/main/config-example.yaml)"
Always select the [same GitHub tag](https://github.com/juanfont/headscale/tags) as the released version you use to
ensure you have the correct example configuration. The `main` branch might contain unreleased changes.
=== "View on GitHub"
- Development version: <https://github.com/juanfont/headscale/blob/main/config-example.yaml>
- Version {{ headscale.version }}: https://github.com/juanfont/headscale/blob/v{{ headscale.version }}/config-example.yaml
=== "Download with `wget`"
```shell
# Development version
wget -O config.yaml https://raw.githubusercontent.com/juanfont/headscale/main/config-example.yaml
# Version {{ headscale.version }}
wget -O config.yaml https://raw.githubusercontent.com/juanfont/headscale/v{{ headscale.version }}/config-example.yaml
```
=== "Download with `curl`"
```shell
# Development version
curl -o config.yaml https://raw.githubusercontent.com/juanfont/headscale/main/config-example.yaml
# Version {{ headscale.version }}
curl -o config.yaml https://raw.githubusercontent.com/juanfont/headscale/v{{ headscale.version }}/config-example.yaml
```

# Debugging and troubleshooting
Headscale and Tailscale provide debug and introspection capabilities that can be helpful when things don't work as
expected. This page explains some debugging techniques to help pinpoint problems.
Please also have a look at [Tailscale's Troubleshooting guide](https://tailscale.com/kb/1023/troubleshooting). It offers
a many tips and suggestions to troubleshoot common issues.
## Tailscale
The Tailscale client itself offers many commands to introspect its state as well as the state of the network:
- [Check local network conditions](https://tailscale.com/kb/1080/cli#netcheck): `tailscale netcheck`
- [Get the client status](https://tailscale.com/kb/1080/cli#status): `tailscale status --json`
- [Get DNS status](https://tailscale.com/kb/1080/cli#dns): `tailscale dns status --all`
- Client logs: `tailscale debug daemon-logs`
- Client netmap: `tailscale debug netmap`
- Test DERP connection: `tailscale debug derp headscale`
- And many more, see: `tailscale debug --help`
Many of the commands are helpful when trying to understand differences between Headscale and Tailscale SaaS.
## Headscale
### Application logging
The log levels `debug` and `trace` can be useful to get more information from Headscale.
```yaml hl_lines="3"
log:
# Valid log levels: panic, fatal, error, warn, info, debug, trace
level: debug
```
### Database logging
The database debug mode logs all database queries. Enable it to see how Headscale interacts with its database. This also
requires the application log level to be set to either `debug` or `trace`.
```yaml hl_lines="3 7"
database:
# Enable debug mode. This setting requires the log.level to be set to "debug" or "trace".
debug: false
log:
# Valid log levels: panic, fatal, error, warn, info, debug, trace
level: debug
```
### Metrics and debug endpoint
Headscale provides a metrics and debug endpoint. It allows to introspect different aspects such as:
- Information about the Go runtime, memory usage and statistics
- Connected nodes and pending registrations
- Active ACLs, filters and SSH policy
- Current DERPMap
- Prometheus metrics
!!! warning "Keep the metrics and debug endpoint private"
The listen address and port can be configured with the `metrics_listen_addr` variable in the [configuration
file](./configuration.md). By default it listens on localhost, port 9090.
Keep the metrics and debug endpoint private to your internal network and don't expose it to the Internet.
The metrics and debug interface can be disabled completely by setting `metrics_listen_addr: null` in the
[configuration file](./configuration.md).
Query metrics via <http://localhost:9090/metrics> and get an overview of available debug information via
<http://localhost:9090/debug/>. Metrics may be queried from outside localhost but the debug interface is subject to
additional protection despite listening on all interfaces.
=== "Direct access"
Access the debug interface directly on the server where Headscale is installed.
```console
curl http://localhost:9090/debug/
```
=== "SSH port forwarding"
Use SSH port forwarding to forward Headscale's metrics and debug port to your device.
```console
ssh <HEADSCALE_SERVER> -L 9090:localhost:9090
```
Access the debug interface on your device by opening <http://localhost:9090/debug/> in your web browser.
=== "Via debug key"
The access control of the debug interface supports the use of a debug key. Traffic is accepted if the path to a
debug key is set via the environment variable `TS_DEBUG_KEY_PATH` and the debug key sent as value for `debugkey`
parameter with each request.
```console
openssl rand -hex 32 | tee debugkey.txt
export TS_DEBUG_KEY_PATH=debugkey.txt
headscale serve
```
Access the debug interface on your device by opening `http://<IP_OF_HEADSCALE>:9090/debug/?debugkey=<DEBUG_KEY>` in
your web browser. The `debugkey` parameter must be sent with every request.
=== "Via debug IP address"
The debug endpoint expects traffic from localhost. A different debug IP address may be configured by setting the
`TS_ALLOW_DEBUG_IP` environment variable before starting Headscale. The debug IP address is ignored when the HTTP
header `X-Forwarded-For` is present.
```console
export TS_ALLOW_DEBUG_IP=192.168.0.10 # IP address of your device
headscale serve
```
Access the debug interface on your device by opening `http://<IP_OF_HEADSCALE>:9090/debug/` in your web browser.
================================================
FILE: docs/ref/derp.md
================================================
# DERP
A [DERP (Designated Encrypted Relay for Packets) server](https://tailscale.com/kb/1232/derp-servers) is mainly used to
relay traffic between two nodes in case a direct connection can't be established. Headscale provides an embedded DERP
server to ensure seamless connectivity between nodes.
## Configuration
DERP related settings are configured within the `derp` section of the [configuration file](./configuration.md). The
following sections only use a few of the available settings, check the [example configuration](./configuration.md) for
all available configuration options.
### Enable embedded DERP
Headscale ships with an embedded DERP server which allows to run your own self-hosted DERP server easily. The embedded
DERP server is disabled by default and needs to be enabled. In addition, you should configure the public IPv4 and public
IPv6 address of your Headscale server for improved connection stability:
```yaml title="config.yaml" hl_lines="3-5"
derp:
server:
enabled: true
ipv4: 198.51.100.1
ipv6: 2001:db8::1
```
Keep in mind that [additional ports are needed to run a DERP server](../setup/requirements.md#ports-in-use). Besides
relaying traffic, it also uses STUN (udp/3478) to help clients discover their public IP addresses and perform NAT
traversal. [Check DERP server connectivity](#check-derp-server-connectivity) to see if everything works.
### Remove Tailscale's DERP servers
Once enabled, Headscale's embedded DERP is added to the list of free-to-use [DERP
servers](https://tailscale.com/kb/1232/derp-servers) offered by Tailscale Inc. To only use Headscale's embedded DERP
server, disable the loading of the default DERP map:
```yaml title="config.yaml" hl_lines="6"
derp:
server:
enabled: true
ipv4: 198.51.100.1
ipv6: 2001:db8::1
urls: []
```
!!! warning "Single point of failure"
Removing Tailscale's DERP servers means that there is now just a single DERP server available for clients. This is a
single point of failure and could hamper connectivity.
[Check DERP server connectivity](#check-derp-server-connectivity) with your embedded DERP server before removing
Tailscale's DERP servers.
### Customize DERP map
The DERP map offered to clients can be customized with a [dedicated YAML-configuration
file](https://github.com/juanfont/headscale/blob/main/derp-example.yaml). This allows to modify previously loaded DERP
maps fetched via URL or to offer your own, custom DERP servers to nodes.
=== "Remove specific DERP regions"
The free-to-use [DERP servers](https://tailscale.com/kb/1232/derp-servers) are organized into regions via a region
ID. You can explicitly disable a specific region by setting its region ID to `null`. The following sample
`derp.yaml` disables the New York DERP region (which has the region ID 1):
```yaml title="derp.yaml"
regions:
1: null
```
Use the following configuration to serve the default DERP map (excluding New York) to nodes:
```yaml title="config.yaml" hl_lines="6 7"
derp:
server:
enabled: false
urls:
- https://controlplane.tailscale.com/derpmap/default
paths:
- /etc/headscale/derp.yaml
```
=== "Provide custom DERP servers"
The following sample `derp.yaml` references two custom regions (`custom-east` with ID 900 and `custom-west` with ID 901)
with one custom DERP server in each region. Each DERP server offers DERP relay via HTTPS on tcp/443, support for captive
portal checks via HTTP on tcp/80 and STUN on udp/3478. See the definitions of
[DERPMap](https://pkg.go.dev/tailscale.com/tailcfg#DERPMap),
[DERPRegion](https://pkg.go.dev/tailscale.com/tailcfg#DERPRegion) and
[DERPNode](https://pkg.go.dev/tailscale.com/tailcfg#DERPNode) for all available options.
```yaml title="derp.yaml"
regions:
900:
regionid: 900
regioncode: custom-east
regionname: My region (east)
nodes:
- name: 900a
regionid: 900
hostname: derp900a.example.com
ipv4: 198.51.100.1
ipv6: 2001:db8::1
canport80: true
901:
regionid: 901
regioncode: custom-west
regionname: My Region (west)
nodes:
- name: 901a
regionid: 901
hostname: derp901a.example.com
ipv4: 198.51.100.2
ipv6: 2001:db8::2
canport80: true
```
Use the following configuration to only serve the two DERP servers from the above `derp.yaml`:
```yaml title="config.yaml" hl_lines="5 6"
derp:
server:
enabled: false
urls: []
paths:
- /etc/headscale/derp.yaml
```
Independent of the custom DERP map, you may choose to [enable the embedded DERP server and have it automatically added
to the custom DERP map](#enable-embedded-derp).
### Verify clients
Access to DERP serves can be restricted to nodes that are members of your Tailnet. Relay access is denied for unknown
clients.
=== "Embedded DERP"
Client verification is enabled by default.
```yaml title="config.yaml" hl_lines="3"
derp:
server:
verify_clients: true
```
=== "3rd-party DERP"
Tailscale's `derper` provides two parameters to configure client verification:
- Use the `-verify-client-url` parameter of the `derper` and point it towards the `/verify` endpoint of your
Headscale server (e.g `https://headscale.example.com/verify`). The DERP server will query your Headscale instance
as soon as a client connects with it to ask whether access should be allowed or denied. Access is allowed if
Headscale knows about the connecting client and denied otherwise.
- The parameter `-verify-client-url-fail-open` controls what should happen when the DERP server can't reach the
Headscale instance. By default, it will allow access if Headscale is unreachable.
## Check DERP server connectivity
Any Tailscale client may be used to introspect the DERP map and to check for connectivity issues with DERP servers.
- Display DERP map: `tailscale debug derp-map`
- Check connectivity with the embedded DERP[^1]:`tailscale debug derp headscale`
Additional DERP related metrics and information is available via the [metrics and debug
endpoint](./debug.md#metrics-and-debug-endpoint).
## Limitations
- The embedded DERP server can't be used for Tailscale's captive portal checks as it doesn't support the `/generate_204`
endpoint via HTTP on port tcp/80.
- There are no speed or throughput optimisations, the main purpose is to assist in node connectivity.
[^1]: This assumes that the default region code of the [configuration file](./configuration.md) is used.

# DNS
Headscale supports [most DNS features](../about/features.md) from Tailscale. DNS related settings can be configured
within the `dns` section of the [configuration file](./configuration.md).
## Setting extra DNS records
Headscale allows to set extra DNS records which are made available via
[MagicDNS](https://tailscale.com/kb/1081/magicdns). Extra DNS records can be configured either via static entries in the
[configuration file](./configuration.md) or from a JSON file that Headscale continuously watches for changes:
- Use the `dns.extra_records` option in the [configuration file](./configuration.md) for entries that are static and
don't change while Headscale is running. Those entries are processed when Headscale is starting up and changes to the
configuration require a restart of Headscale.
- For dynamic DNS records that may be added, updated or removed while Headscale is running or DNS records that are
generated by scripts the option `dns.extra_records_path` in the [configuration file](./configuration.md) is useful.
Set it to the absolute path of the JSON file containing DNS records and Headscale processes this file as it detects
changes.
An example use case is to serve multiple apps on the same host via a reverse proxy like NGINX, in this case a Prometheus
monitoring stack. This allows to nicely access the service with "http://grafana.myvpn.example.com" instead of the
hostname and port combination "http://hostname-in-magic-dns.myvpn.example.com:3000".
!!! warning "Limitations"
Currently, [only A and AAAA records are processed by Tailscale](https://github.com/tailscale/tailscale/blob/v1.86.5/ipn/ipnlocal/node_backend.go#L662).
1. Configure extra DNS records using one of the available configuration options:
=== "Static entries, via `dns.extra_records`"
```yaml title="config.yaml"
dns:
...
extra_records:
- name: "grafana.myvpn.example.com"
type: "A"
value: "100.64.0.3"
- name: "prometheus.myvpn.example.com"
type: "A"
value: "100.64.0.3"
...
```
Restart your headscale instance.
=== "Dynamic entries, via `dns.extra_records_path`"
```json title="extra-records.json"
[
{
"name": "grafana.myvpn.example.com",
"type": "A",
"value": "100.64.0.3"
},
{
"name": "prometheus.myvpn.example.com",
"type": "A",
"value": "100.64.0.3"
}
]
```
Headscale picks up changes to the above JSON file automatically.
!!! tip "Good to know"
- The `dns.extra_records_path` option in the [configuration file](./configuration.md) needs to reference the
JSON file containing extra DNS records.
- Be sure to "sort keys" and produce a stable output in case you generate the JSON file with a script.
Headscale uses a checksum to detect changes to the file and a stable output avoids unnecessary processing.
1. Verify that DNS records are properly set using the DNS querying tool of your choice:
=== "Query with dig"
```console
dig +short grafana.myvpn.example.com
100.64.0.3
```
=== "Query with drill"
```console
drill -Q grafana.myvpn.example.com
100.64.0.3
```
1. Optional: Setup the reverse proxy
The motivating example here was to be able to access internal monitoring services on the same host without
specifying a port, depicted as NGINX configuration snippet:
```nginx title="nginx.conf"
server {
listen 80;
listen [::]:80;
server_name grafana.myvpn.example.com;
location / {
proxy_pass http://localhost:3000;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
```

# Running headscale behind a reverse proxy
!!! warning "Community documentation"
This page is not actively maintained by the headscale authors and is
written by community members. It is _not_ verified by headscale developers.
**It might be outdated and it might miss necessary steps**.
Running headscale behind a reverse proxy is useful when running multiple applications on the same server, and you want to reuse the same external IP and port - usually tcp/443 for HTTPS.
### WebSockets
The reverse proxy MUST be configured to support WebSockets to communicate with Tailscale clients.
WebSockets support is also required when using the Headscale [embedded DERP server](../derp.md). In this case, you will also need to expose the UDP port used for STUN (by default, udp/3478). Please check our [config-example.yaml](https://github.com/juanfont/headscale/blob/main/config-example.yaml).
### Cloudflare
Running headscale behind a cloudflare proxy or cloudflare tunnel is not supported and will not work as Cloudflare does not support WebSocket POSTs as required by the Tailscale protocol. See [this issue](https://github.com/juanfont/headscale/issues/1468)
### TLS
Headscale can be configured not to use TLS, leaving it to the reverse proxy to handle. Add the following configuration values to your headscale config file.
```yaml title="config.yaml"
server_url: https://<YOUR_SERVER_NAME> # This should be the FQDN at which headscale will be served
listen_addr: 0.0.0.0:8080
metrics_listen_addr: 0.0.0.0:9090
tls_cert_path: ""
tls_key_path: ""
```
## nginx
The following example configuration can be used in your nginx setup, substituting values as necessary. `<IP:PORT>` should be the IP address and port where headscale is running. In most cases, this will be `http://localhost:8080`.
```nginx title="nginx.conf"
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
server {
listen 80;
listen [::]:80;
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name <YOUR_SERVER_NAME>;
ssl_certificate <PATH_TO_CERT>;
ssl_certificate_key <PATH_CERT_KEY>;
ssl_protocols TLSv1.2 TLSv1.3;
location / {
proxy_pass http://<IP:PORT>;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_set_header Host $server_name;
proxy_redirect http:// https://;
proxy_buffering off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
add_header Strict-Transport-Security "max-age=15552000; includeSubDomains" always;
}
}
```
## istio/envoy
If you using [Istio](https://istio.io/) ingressgateway or [Envoy](https://www.envoyproxy.io/) as reverse proxy, there are some tips for you. If not set, you may see some debug log in proxy as below:
```log
Sending local reply with details upgrade_failed
```
### Envoy
You need to add a new upgrade_type named `tailscale-control-protocol`. [see details](https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/network/http_connection_manager/v3/http_connection_manager.proto#extensions-filters-network-http-connection-manager-v3-httpconnectionmanager-upgradeconfig)
### Istio
Same as envoy, we can use `EnvoyFilter` to add upgrade_type.
```yaml
apiVersion: networking.istio.io/v1alpha3
kind: EnvoyFilter
metadata:
name: headscale-behind-istio-ingress
namespace: istio-system
spec:
configPatches:
- applyTo: NETWORK_FILTER
match:
listener:
filterChain:
filter:
name: envoy.filters.network.http_connection_manager
patch:
operation: MERGE
value:
typed_config:
"@type": type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager
upgrade_configs:
- upgrade_type: tailscale-control-protocol
```
## Caddy
The following Caddyfile is all that is necessary to use Caddy as a reverse proxy for headscale, in combination with the `config.yaml` specifications above to disable headscale's built in TLS. Replace values as necessary - `<YOUR_SERVER_NAME>` should be the FQDN at which headscale will be served, and `<IP:PORT>` should be the IP address and port where headscale is running. In most cases, this will be `localhost:8080`.
```none title="Caddyfile"
<YOUR_SERVER_NAME> {
reverse_proxy <IP:PORT>
}
```
Caddy v2 will [automatically](https://caddyserver.com/docs/automatic-https) provision a certificate for your domain/subdomain, force HTTPS, and proxy websockets - no further configuration is necessary.
For a slightly more complex configuration which utilizes Docker containers to manage Caddy, headscale, and Headscale-UI, [Guru Computing's guide](https://blog.gurucomputing.com.au/smart-vpns-with-headscale/) is an excellent reference.
## Apache
The following minimal Apache config will proxy traffic to the headscale instance on `<IP:PORT>`. Note that `upgrade=any` is required as a parameter for `ProxyPass` so that WebSockets traffic whose `Upgrade` header value is not equal to `WebSocket` (i. e. Tailscale Control Protocol) is forwarded correctly. See the [Apache docs](https://httpd.apache.org/docs/2.4/mod/mod_proxy_wstunnel.html) for more information on this.
```apache title="apache.conf"
<VirtualHost *:443>
ServerName <YOUR_SERVER_NAME>
ProxyPreserveHost On
ProxyPass / http://<IP:PORT>/ upgrade=any
SSLEngine On
SSLCertificateFile <PATH_TO_CERT>
SSLCertificateKeyFile <PATH_CERT_KEY>
</VirtualHost>
```

# OpenID Connect
Headscale supports authentication via external identity providers using OpenID Connect (OIDC). It features:
- Auto configuration via OpenID Connect Discovery Protocol
- [Proof Key for Code Exchange (PKCE) code verification](#enable-pkce-recommended)
- [Authorization based on a user's domain, email address or group membership](#authorize-users-with-filters)
- Synchronization of [standard OIDC claims](#supported-oidc-claims)
Please see [limitations](#limitations) for known issues and limitations.
## Configuration
OpenID requires configuration in Headscale and your identity provider:
- Headscale: The `oidc` section of the Headscale [configuration](configuration.md) contains all available configuration
options along with a description and their default values.
- Identity provider: Please refer to the official documentation of your identity provider for specific instructions.
Additionally, there might be some useful hints in the [Identity provider specific
configuration](#identity-provider-specific-configuration) section below.
### Basic configuration
A basic configuration connects Headscale to an identity provider and typically requires:
- OpenID Connect Issuer URL from the identity provider. Headscale uses the OpenID Connect Discovery Protocol 1.0 to
automatically obtain OpenID configuration parameters (example: `https://sso.example.com`).
- Client ID from the identity provider (example: `headscale`).
- Client secret generated by the identity provider (example: `generated-secret`).
- Redirect URI for your identity provider (example: `https://headscale.example.com/oidc/callback`).
=== "Headscale"
```yaml
oidc:
issuer: "https://sso.example.com"
client_id: "headscale"
client_secret: "generated-secret"
```
=== "Identity provider"
- Create a new confidential client (`Client ID`, `Client secret`)
- Add Headscale's OIDC callback URL as valid redirect URL: `https://headscale.example.com/oidc/callback`
- Configure additional parameters to improve user experience such as: name, description, logo, …
### Enable PKCE (recommended)
Proof Key for Code Exchange (PKCE) adds an additional layer of security to the OAuth 2.0 authorization code flow by
preventing authorization code interception attacks, see: <https://datatracker.ietf.org/doc/html/rfc7636>. PKCE is
recommended and needs to be configured for Headscale and the identity provider alike:
=== "Headscale"
```yaml hl_lines="5-6"
oidc:
issuer: "https://sso.example.com"
client_id: "headscale"
client_secret: "generated-secret"
pkce:
enabled: true
```
=== "Identity provider"
- Enable PKCE for the headscale client
- Set the PKCE challenge method to "S256"
### Authorize users with filters
Headscale allows to filter for allowed users based on their domain, email address or group membership. These filters can
be helpful to apply additional restrictions and control which users are allowed to join. Filters are disabled by
default, users are allowed to join once the authentication with the identity provider succeeds. In case multiple filters
are configured, a user needs to pass all of them.
=== "Allowed domains"
- Check the email domain of each authenticating user against the list of allowed domains and only authorize users
whose email domain matches `example.com`.
- A verified email address is required [unless email verification is disabled](#control-email-verification).
- Access allowed: `alice@example.com`
- Access denied: `bob@example.net`
```yaml hl_lines="5-6"
oidc:
issuer: "https://sso.example.com"
client_id: "headscale"
client_secret: "generated-secret"
allowed_domains:
- "example.com"
```
=== "Allowed users/emails"
- Check the email address of each authenticating user against the list of allowed email addresses and only authorize
users whose email is part of the `allowed_users` list.
- A verified email address is required [unless email verification is disabled](#control-email-verification).
- Access allowed: `alice@example.com`, `bob@example.net`
- Access denied: `mallory@example.net`
```yaml hl_lines="5-7"
oidc:
issuer: "https://sso.example.com"
client_id: "headscale"
client_secret: "generated-secret"
allowed_users:
- "alice@example.com"
- "bob@example.net"
```
=== "Allowed groups"
- Use the OIDC `groups` claim of each authenticating user to get their group membership and only authorize users
which are members in at least one of the referenced groups.
- Access allowed: users in the `headscale_users` group
- Access denied: users without groups, users with other groups
```yaml hl_lines="5-7"
oidc:
issuer: "https://sso.example.com"
client_id: "headscale"
client_secret: "generated-secret"
scope: ["openid", "profile", "email", "groups"]
allowed_groups:
- "headscale_users"
```
### Control email verification
Headscale uses the `email` claim from the identity provider to synchronize the email address to its user profile. By
default, a user's email address is only synchronized when the identity provider reports the email address as verified
via the `email_verified: true` claim.
Unverified emails may be allowed in case an identity provider does not send the `email_verified` claim or email
verification is not required. In that case, a user's email address is always synchronized to the user profile.
```yaml hl_lines="5"
oidc:
issuer: "https://sso.example.com"
client_id: "headscale"
client_secret: "generated-secret"
email_verified_required: false
```
### Customize node expiration
The node expiration is the amount of time a node is authenticated with OpenID Connect until it expires and needs to
reauthenticate. The default node expiration is 180 days. This can either be customized or set to the expiration from the
Access Token.
=== "Customize node expiration"
```yaml hl_lines="5"
oidc:
issuer: "https://sso.example.com"
client_id: "headscale"
client_secret: "generated-secret"
expiry: 30d # Use 0 to disable node expiration
```
=== "Use expiration from Access Token"
Please keep in mind that the Access Token is typically a short-lived token that expires within a few minutes. You
will have to configure token expiration in your identity provider to avoid frequent re-authentication.
```yaml hl_lines="5"
oidc:
issuer: "https://sso.example.com"
client_id: "headscale"
client_secret: "generated-secret"
use_expiry_from_token: true
```
!!! tip "Expire a node and force re-authentication"
A node can be expired immediately via:
```console
headscale node expire -i <NODE_ID>
```
### Reference a user in the policy
You may refer to users in the Headscale policy via:
- Email address
- Username
- Provider identifier (this value is currently only available from the [API](api.md), database or directly from your
identity provider)
!!! note "A user identifier in the policy must contain a single `@`"
The Headscale policy requires a single `@` to reference a user. If the username or provider identifier doesn't
already contain a single `@`, it needs to be appended at the end. For example: the username `ssmith` has to be
written as `ssmith@` to be correctly identified as user within the policy.
!!! warning "Email address or username might be updated by users"
Many identity providers allow users to update their own profile. Depending on the identity provider and its
configuration, the values for username or email address might change over time. This might have unexpected
consequences for Headscale where a policy might no longer work or a user might obtain more access by hijacking an
existing username or email address.
!!! tip "Howto use the provider identifier in the policy"
The provider identifier uniquely identifies an OIDC user and a well-behaving identity provider guarantees that this
value never changes for a particular user. It is usually an opaque and long string and its value is currently only
available from the [API](api.md), database or directly from your identity provider).
Use the [API](api.md) with the `/api/v1/user` endpoint to fetch the provider identifier (`providerId`). The value
(be sure to append an `@` in case the provider identifier doesn't already contain an `@` somewhere) can be used
directly to reference a user in the policy. To improve readability of the policy, one may use the `groups` section
as an alias:
```json
{
"groups": {
"group:alice": [
"https://soo.example.com/oauth2/openid/59ac9125-c31b-46c5-814e-06242908cf57@"
]
},
"acls": [
{
"action": "accept",
"src": ["group:alice"],
"dst": ["*:*"]
}
]
}
```
## Supported OIDC claims
Headscale uses [the standard OIDC claims](https://openid.net/specs/openid-connect-core-1_0.html#StandardClaims) to
populate and update its local user profile on each login. OIDC claims are read from the ID Token and from the UserInfo
endpoint.
| Headscale profile | OIDC claim | Notes / examples |
| ------------------- | -------------------- | ------------------------------------------------------------------------------------------------- |
| email address | `email` | Only verified emails are synchronized, unless `email_verified_required: false` is configured |
| display name | `name` | eg: `Sam Smith` |
| username | `preferred_username` | Depends on identity provider, eg: `ssmith`, `ssmith@idp.example.com`, `\\example.com\ssmith` |
| profile picture | `picture` | URL to a profile picture or avatar |
| provider identifier | `iss`, `sub` | A stable and unique identifier for a user, typically a combination of `iss` and `sub` OIDC claims |
| | `groups` | [Only used to filter for allowed groups](#authorize-users-with-filters) |
## Limitations
- Support for OpenID Connect aims to be generic and vendor independent. It offers only limited support for quirks of
specific identity providers.
- OIDC groups cannot be used in ACLs.
- The username provided by the identity provider needs to adhere to this pattern:
- The username must be at least two characters long.
- It must only contain letters, digits, hyphens, dots, underscores, and up to a single `@`.
- The username must start with a letter.
Please see the [GitHub label "OIDC"](https://github.com/juanfont/headscale/labels/OIDC) for OIDC related issues.
## Identity provider specific configuration
!!! warning "Third-party software and services"
This section of the documentation is specific for third-party software and services. We recommend users read the
third-party documentation on how to configure and integrate an OIDC client. Please see the [Configuration
section](#configuration) for a description of Headscale's OIDC related configuration settings.
Any identity provider with OpenID Connect support should "just work" with Headscale. The following identity providers
are known to work:
- [Authelia](#authelia)
- [Authentik](#authentik)
- [Kanidm](#kanidm)
- [Keycloak](#keycloak)
### Authelia
Authelia is fully supported by Headscale.
### Authentik
- Authentik is fully supported by Headscale.
- [Headscale does not support JSON Web Encryption](https://github.com/juanfont/headscale/issues/2446). Leave the field
`Encryption Key` in the providers section unset.
- See Authentik's [Integrate with Headscale](https://integrations.goauthentik.io/networking/headscale/)
### Google OAuth
!!! warning "No username due to missing preferred_username"
Google OAuth does not send the `preferred_username` claim when the scope `profile` is requested. The username in
Headscale will be blank/not set.
In order to integrate Headscale with Google, you'll need to have a [Google Cloud
Console](https://console.cloud.google.com) account.
Google OAuth has a [verification process](https://support.google.com/cloud/answer/9110914?hl=en) if you need to have
users authenticate who are outside of your domain. If you only need to authenticate users from your domain name (ie
`@example.com`), you don't need to go through the verification process.
However if you don't have a domain, or need to add users outside of your domain, you can manually add emails via Google
Console.
#### Steps
1. Go to [Google Console](https://console.cloud.google.com) and login or create an account if you don't have one.
1. Create a project (if you don't already have one).
1. On the left hand menu, go to `APIs and services` -> `Credentials`
1. Click `Create Credentials` -> `OAuth client ID`
1. Under `Application Type`, choose `Web Application`
1. For `Name`, enter whatever you like
1. Under `Authorised redirect URIs`, add Headscale's OIDC callback URL: `https://headscale.example.com/oidc/callback`
1. Click `Save` at the bottom of the form
1. Take note of the `Client ID` and `Client secret`, you can also download it for reference if you need it.
1. [Configure Headscale following the "Basic configuration" steps](#basic-configuration). The issuer URL for Google
OAuth is: `https://accounts.google.com`.
### Kanidm
- Kanidm is fully supported by Headscale.
- Groups for the [allowed groups filter](#authorize-users-with-filters) need to be specified with their full SPN, for
example: `headscale_users@sso.example.com`.
- Kanidm sends the full SPN (`alice@sso.example.com`) as `preferred_username` by default. Headscale stores this value as
username which might be confusing as the username and email fields now contain values that look like an email address.
[Kanidm can be configured to send the short username as `preferred_username` attribute
instead](https://kanidm.github.io/kanidm/stable/integrations/oauth2.html#short-names):
```console
kanidm system oauth2 prefer-short-username <client name>
```
Once configured, the short username in Headscale will be `alice` and can be referred to as `alice@` in the policy.
### Keycloak
Keycloak is fully supported by Headscale.
#### Additional configuration to use the allowed groups filter
Keycloak has no built-in client scope for the OIDC `groups` claim. This extra configuration step is **only** needed if
you need to [authorize access based on group membership](#authorize-users-with-filters).
- Create a new client scope `groups` for OpenID Connect:
- Configure a `Group Membership` mapper with name `groups` and the token claim name `groups`.
- Add the mapper to at least the UserInfo endpoint.
- Configure the new client scope for your Headscale client:
- Edit the Headscale client.
- Search for the client scope `group`.
- Add it with assigned type `Default`.
- [Configure the allowed groups in Headscale](#authorize-users-with-filters). How groups need to be specified depends on
Keycloak's `Full group path` option:
- `Full group path` is enabled: groups contain their full path, e.g. `/top/group1`
- `Full group path` is disabled: only the name of the group is used, e.g. `group1`
### Microsoft Entra ID
In order to integrate Headscale with Microsoft Entra ID, you'll need to provision an App Registration with the correct
scopes and redirect URI.
[Configure Headscale following the "Basic configuration" steps](#basic-configuration). The issuer URL for Microsoft
Entra ID is: `https://login.microsoftonline.com/<tenant-UUID>/v2.0`. The following `extra_params` might be useful:
- `domain_hint: example.com` to use your own domain
- `prompt: select_account` to force an account picker during login
When using Microsoft Entra ID together with the [allowed groups filter](#authorize-users-with-filters), configure the
Headscale OIDC scope without the `groups` claim, for example:
```yaml
oidc:
scope: ["openid", "profile", "email"]
```
Groups for the [allowed groups filter](#authorize-users-with-filters) need to be specified with their group ID(UUID) instead
of the group name.
## Switching OIDC providers
Headscale only supports a single OIDC provider in its configuration, but it does store the provider identifier of each user. When switching providers, this might lead to issues with existing users: all user details (name, email, groups) might be identical with the new provider, but the identifier will differ. Headscale will be unable to create a new user as the name and email will already be in use for the existing users.
At this time, you will need to manually update the `provider_identifier` column in the `users` table for each user with the appropriate value for the new provider. The identifier is built from the `iss` and `sub` claims of the OIDC ID token, for example `https://id.example.com/12340987`.

# Registration methods
Headscale supports multiple ways to register a node. The preferred registration method depends on the identity of a node
and your use case.
## Identity model
Tailscale's identity model distinguishes between personal and tagged nodes:
- A personal node (or user-owned node) is owned by a human and typically refers to end-user devices such as laptops,
workstations or mobile phones. End-user devices are managed by a single user.
- A tagged node (or service-based node or non-human node) provides services to the network. Common examples include web-
and database servers. Those nodes are typically managed by a team of users. Some additional restrictions apply for
tagged nodes, e.g. a tagged node is not allowed to [Tailscale SSH](https://tailscale.com/kb/1193/tailscale-ssh) into a
personal node.
Headscale implements Tailscale's identity model and distinguishes between personal and tagged nodes where a personal
node is owned by a Headscale user and a tagged node is owned by a tag. Tagged devices are grouped under the special user
`tagged-devices`.
## Registration methods
There are two main ways to register new nodes, [web authentication](#web-authentication) and [registration with a pre
authenticated key](#pre-authenticated-key). Both methods can be used to register personal and tagged nodes.
### Web authentication
Web authentication is the default method to register a new node. It's interactive, where the client initiates the
registration and the Headscale administrator needs to approve the new node before it is allowed to join the network. A
node can be approved with:
- Headscale CLI (described in this documentation)
- [Headscale API](api.md)
- Or delegated to an identity provider via [OpenID Connect](oidc.md)
Web authentication relies on the presence of a Headscale user. Use the `headscale users` command to create a new user:
```console
headscale users create <USER>
```
=== "Personal devices"
Run `tailscale up` to login your personal device:
```console
tailscale up --login-server <YOUR_HEADSCALE_URL>
```
Usually, a browser window with further instructions is opened. This page explains how to complete the registration
on your Headscale server and it also prints the Auth ID required to approve the node:
```console
headscale auth register --user <USER> --auth-id <AUTH_ID>
```
Congrations, the registration of your personal node is complete and it should be listed as "online" in the output of
`headscale nodes list`. The "User" column displays `<USER>` as the owner of the node.
=== "Tagged devices"
Your Headscale user needs to be authorized to register tagged devices. This authorization is specified in the
[`tagOwners`](https://tailscale.com/kb/1337/policy-syntax#tag-owners) section of the [ACL](acls.md). A simple
example looks like this:
```json title="The user alice can register nodes tagged with tag:server"
{
"tagOwners": {
"tag:server": ["alice@"]
},
// more rules
}
```
Run `tailscale up` and provide at least one tag to login a tagged device:
```console
tailscale up --login-server <YOUR_HEADSCALE_URL> --advertise-tags tag:<TAG>
```
Usually, a browser window with further instructions is opened. This page explains how to complete the registration
on your Headscale server and it also prints the Auth ID required to approve the node:
```console
headscale auth register --user <USER> --auth-id <AUTH_ID>
```
Headscale checks that `<USER>` is allowed to register a node with the specified tag(s) and then transfers ownership
of the new node to the special user `tagged-devices`. The registration of a tagged node is complete and it should be
listed as "online" in the output of `headscale nodes list`. The "User" column displays `tagged-devices` as the owner
of the node. See the "Tags" column for the list of assigned tags.
### Pre authenticated key
Registration with a pre authenticated key (or auth key) is a non-interactive way to register a new node. The Headscale
administrator creates a preauthkey upfront and this preauthkey can then be used to register a node non-interactively.
Its best suited for automation.
=== "Personal devices"
A personal node is always assigned to a Headscale user. Use the `headscale users` command to create a new user:
```console
headscale users create <USER>
```
Use the `headscale user list` command to learn its `<USER_ID>` and create a new pre authenticated key for your user:
```console
headscale preauthkeys create --user <USER_ID>
```
The above prints a pre authenticated key with the default settings (can be used once and is valid for one hour). Use
this auth key to register a node non-interactively:
```console
tailscale up --login-server <YOUR_HEADSCALE_URL> --authkey <YOUR_AUTH_KEY>
```
Congrations, the registration of your personal node is complete and it should be listed as "online" in the output of
`headscale nodes list`. The "User" column displays `<USER>` as the owner of the node.
=== "Tagged devices"
Create a new pre authenticated key and provide at least one tag:
```console
headscale preauthkeys create --tags tag:<TAG>
```
The above prints a pre authenticated key with the default settings (can be used once and is valid for one hour). Use
this auth key to register a node non-interactively. You don't need to provide the `--advertise-tags` parameter as
the tags are automatically read from the pre authenticated key:
```console
tailscale up --login-server <YOUR_HEADSCALE_URL> --authkey <YOUR_AUTH_KEY>
```
The registration of a tagged node is complete and it should be listed as "online" in the output of
`headscale nodes list`. The "User" column displays `tagged-devices` as the owner of the node. See the "Tags" column for the list of
assigned tags.

================================================
# Routes
Headscale supports route advertising and can be used to manage [subnet routers](https://tailscale.com/kb/1019/subnets)
and [exit nodes](https://tailscale.com/kb/1103/exit-nodes) for a tailnet.
- [Subnet routers](#subnet-router) may be used to connect an existing network such as a virtual
private cloud or an on-premise network with your tailnet. Use a subnet router to access devices where Tailscale can't
be installed or to gradually rollout Tailscale.
- [Exit nodes](#exit-node) can be used to route all Internet traffic for another Tailscale
node. Use it to securely access the Internet on an untrusted Wi-Fi or to access online services that expect traffic
from a specific IP address.
## Subnet router
The setup of a subnet router requires double opt-in, once from a subnet router and once on the control server to allow
its use within the tailnet. Optionally, use [`autoApprovers` to automatically approve routes from a subnet
router](#automatically-approve-routes-of-a-subnet-router).
### Setup a subnet router
#### Configure a node as subnet router
Register a node and advertise the routes it should handle as comma separated list:
```console
$ sudo tailscale up --login-server <YOUR_HEADSCALE_URL> --advertise-routes=10.0.0.0/8,192.168.0.0/24
```
If the node is already registered, it can advertise new routes or update previously announced routes with:
```console
$ sudo tailscale set --advertise-routes=10.0.0.0/8,192.168.0.0/24
```
Finally, [enable IP forwarding](#enable-ip-forwarding) to route traffic.
#### Enable the subnet router on the control server
The routes of a tailnet can be displayed with the `headscale nodes list-routes` command. A subnet router with the
hostname `myrouter` announced the IPv4 networks `10.0.0.0/8` and `192.168.0.0/24`. Those need to be approved before they
can be used.
```console
$ headscale nodes list-routes
ID | Hostname | Approved | Available | Serving (Primary)
1 | myrouter | | 10.0.0.0/8 |
| | | 192.168.0.0/24 |
```
Approve all desired routes of a subnet router by specifying them as comma separated list:
```console
$ headscale nodes approve-routes --identifier 1 --routes 10.0.0.0/8,192.168.0.0/24
Node updated
```
The node `myrouter` can now route the IPv4 networks `10.0.0.0/8` and `192.168.0.0/24` for the tailnet.
```console
$ headscale nodes list-routes
ID | Hostname | Approved | Available | Serving (Primary)
1 | myrouter | 10.0.0.0/8 | 10.0.0.0/8 | 10.0.0.0/8
| | 192.168.0.0/24 | 192.168.0.0/24 | 192.168.0.0/24
```
#### Use the subnet router
To accept routes advertised by a subnet router on a node:
```console
$ sudo tailscale set --accept-routes
```
Please refer to the official [Tailscale
documentation](https://tailscale.com/kb/1019/subnets#use-your-subnet-routes-from-other-devices) for how to use a subnet
router on different operating systems.
### Restrict the use of a subnet router with ACL
The routes announced by subnet routers are available to the nodes in a tailnet. By default, without an ACL enabled, all
nodes can accept and use such routes. Configure an ACL to explicitly manage who can use routes.
The ACL snippet below defines three hosts, a subnet router `router`, a regular node `node` and `service.example.net` as
internal service that can be reached via a route on the subnet router `router`. It allows the node `node` to access
`service.example.net` on port 80 and 443 which is reachable via the subnet router. Access to the subnet router itself is
denied.
```json title="Access the routes of a subnet router without the subnet router itself"
{
"hosts": {
// the router is not referenced but announces 192.168.0.0/24"
"router": "100.64.0.1/32",
"node": "100.64.0.2/32",
"service.example.net": "192.168.0.1/32"
},
"acls": [
{
"action": "accept",
"src": ["node"],
"dst": ["service.example.net:80,443"]
}
]
}
```
### Automatically approve routes of a subnet router
The initial setup of a subnet router usually requires manual approval of their announced routes on the control server
before they can be used by a node in a tailnet. Headscale supports the `autoApprovers` section of an ACL to automate the
approval of routes served with a subnet router.
The ACL snippet below defines the tag `tag:router` owned by the user `alice`. This tag is used for `routes` in the
`autoApprovers` section. The IPv4 route `192.168.0.0/24` is automatically approved once announced by a subnet router
that advertises the tag `tag:router`.
```json title="Subnet routers tagged with tag:router are automatically approved"
{
"tagOwners": {
"tag:router": ["alice@"]
},
"autoApprovers": {
"routes": {
"192.168.0.0/24": ["tag:router"]
}
},
"acls": [
// more rules
]
}
```
Advertise the route `192.168.0.0/24` from a subnet router that also advertises the tag `tag:router` when joining the tailnet:
```console
$ sudo tailscale up --login-server <YOUR_HEADSCALE_URL> --advertise-tags tag:router --advertise-routes 192.168.0.0/24
```
Please see the [official Tailscale documentation](https://tailscale.com/kb/1337/acl-syntax#autoapprovers) for more
information on auto approvers.
## Exit node
The setup of an exit node requires double opt-in, once from an exit node and once on the control server to allow its use
within the tailnet. Optionally, use [`autoApprovers` to automatically approve an exit
node](#automatically-approve-an-exit-node-with-auto-approvers).
### Setup an exit node
#### Configure a node as exit node
Register a node and make it advertise itself as an exit node:
```console
$ sudo tailscale up --login-server <YOUR_HEADSCALE_URL> --advertise-exit-node
```
If the node is already registered, it can advertise exit capabilities like this:
```console
$ sudo tailscale set --advertise-exit-node
```
Finally, [enable IP forwarding](#enable-ip-forwarding) to route traffic.
#### Enable the exit node on the control server
The routes of a tailnet can be displayed with the `headscale nodes list-routes` command. An exit node can be recognized
by its announced routes: `0.0.0.0/0` for IPv4 and `::/0` for IPv6. The exit node with the hostname `myexit` is already
available, but needs to be approved:
```console
$ headscale nodes list-routes
ID | Hostname | Approved | Available | Serving (Primary)
1 | myexit | | 0.0.0.0/0 |
| | | ::/0 |
```
For exit nodes, it is sufficient to approve either the IPv4 or IPv6 route. The other will be approved automatically.
```console
$ headscale nodes approve-routes --identifier 1 --routes 0.0.0.0/0
Node updated
```
The node `myexit` is now approved as exit node for the tailnet:
```console
$ headscale nodes list-routes
ID | Hostname | Approved | Available | Serving (Primary)
1 | myexit | 0.0.0.0/0 | 0.0.0.0/0 | 0.0.0.0/0
| | ::/0 | ::/0 | ::/0
```
#### Use the exit node
The exit node can now be used on a node with:
```console
$ sudo tailscale set --exit-node myexit
```
Please refer to the official [Tailscale documentation](https://tailscale.com/kb/1103/exit-nodes#use-the-exit-node) for
how to use an exit node on different operating systems.
### Restrict the use of an exit node with ACL
An exit node is offered to all nodes in a tailnet. By default, without an ACL enabled, all nodes in a tailnet can select
and use an exit node. Configure `autogroup:internet` in an ACL rule to restrict who can use _any_ of the available exit
nodes.
```json title="Example use of autogroup:internet"
{
"acls": [
{
"action": "accept",
"src": ["..."],
"dst": ["autogroup:internet:*"]
}
]
}
```
### Restrict access to exit nodes per user or group
A user can use _any_ of the available exit nodes with `autogroup:internet`. Alternatively, the ACL snippet below assigns
each user a specific exit node while hiding all other exit nodes. The user `alice` can only use exit node `exit1` while
user `bob` can only use exit node `exit2`.
```json title="Assign each user a dedicated exit node"
{
"hosts": {
"exit1": "100.64.0.1/32",
"exit2": "100.64.0.2/32"
},
"acls": [
{
"action": "accept",
"src": ["alice@"],
"dst": ["exit1:*"]
},
{
"action": "accept",
"src": ["bob@"],
"dst": ["exit2:*"]
}
]
}
```
!!! warning
- The above implementation is Headscale specific and will likely be removed once [support for
`via`](https://github.com/juanfont/headscale/issues/2409) is available.
- Beware that a user can also connect to any port of the exit node itself.
### Automatically approve an exit node with auto approvers
The initial setup of an exit node usually requires manual approval on the control server before it can be used by a node
in a tailnet. Headscale supports the `autoApprovers` section of an ACL to automate the approval of a new exit node as
soon as it joins the tailnet.
The ACL snippet below defines the tag `tag:exit` owned by the user `alice`. This tag is used for `exitNode` in the
`autoApprovers` section. A new exit node that advertises the tag `tag:exit` is automatically approved:
```json title="Exit nodes tagged with tag:exit are automatically approved"
{
"tagOwners": {
"tag:exit": ["alice@"]
},
"autoApprovers": {
"exitNode": ["tag:exit"]
},
"acls": [
// more rules
]
}
```
Advertise a node as exit node and also advertise the tag `tag:exit` when joining the tailnet:
```console
$ sudo tailscale up --login-server <YOUR_HEADSCALE_URL> --advertise-tags tag:exit --advertise-exit-node
```
Please see the [official Tailscale documentation](https://tailscale.com/kb/1337/acl-syntax#autoapprovers) for more
information on auto approvers.
## High availability
Headscale has limited support for high availability routing. Multiple subnet routers with overlapping routes or multiple
exit nodes can be used to provide high availability for users. If one router node goes offline, another one can serve
the same routes to clients. Please see the official [Tailscale documentation on high
availability](https://tailscale.com/kb/1115/high-availability#subnet-router-high-availability) for details.
!!! bug
In certain situations it might take up to 16 minutes for Headscale to detect a node as offline. A failover node
might not be selected fast enough, if such a node is used as subnet router or exit node causing service
interruptions for clients. See [issue 2129](https://github.com/juanfont/headscale/issues/2129) for more information.
## Troubleshooting
### Enable IP forwarding
A subnet router or exit node is routing traffic on behalf of other nodes and thus requires IP forwarding. Check the
official [Tailscale documentation](https://tailscale.com/kb/1019/subnets/?tab=linux#enable-ip-forwarding) for how to
enable IP forwarding.
================================================
FILE: docs/ref/tags.md
================================================
# Tags
Headscale supports Tailscale tags. Please read [Tailscale's tag documentation](https://tailscale.com/kb/1068/tags) to
learn how tags work and how to use them.
Tags can be applied during [node registration](registration.md):
- using the `--advertise-tags` flag, see [web authentication for tagged devices](registration.md#__tabbed_1_2)
- using a tagged pre authenticated key, see [how to create and use it](registration.md#__tabbed_2_2)
Administrators can manage tags with:
- Headscale CLI
- [Headscale API](api.md)
## Common operations
### Manage tags for a node
Run `headscale nodes list` to list the tags for a node.
Use the `headscale nodes tag` command to modify the tags for a node. At least one tag is required and multiple tags can
be provided as comma separated list. The following command sets the tags `tag:server` and `tag:prod` on node with ID 1:
```console
headscale nodes tag -i 1 -t tag:server,tag:prod
```
### Convert from personal to tagged node
Use the `headscale nodes tag` command to convert a personal (user-owned) node to a tagged node:
```console
headscale nodes tag -i <NODE_ID> -t <TAG>
```
The node is now owned by the special user `tagged-devices` and has the specified tags assigned to it.
### Convert from tagged to personal node
Tagged nodes can return to personal (user-owned) nodes by re-authenticating with:
```console
tailscale up --login-server <YOUR_HEADSCALE_URL> --advertise-tags= --force-reauth
```
Usually, a browser window with further instructions is opened. This page explains how to complete the registration on
your Headscale server and it also prints the Auth ID required to approve the node:
```console
headscale auth register --user <USER> --auth-id <AUTH_ID>
```
All previously assigned tags get removed and the node is now owned by the user specified in the above command.
================================================
FILE: docs/ref/tls.md
================================================
# Running the service via TLS (optional)
## Bring your own certificate
Headscale can be configured to expose its web service via TLS. To configure the certificate and key file manually, set the `tls_cert_path` and `tls_key_path` configuration parameters. If the path is relative, it will be interpreted as relative to the directory the configuration file was read from.
```yaml title="config.yaml"
tls_cert_path: ""
tls_key_path: ""
```
The certificate should contain the full chain, else some clients, like the Tailscale Android client, will reject it.
## Let's Encrypt / ACME
To get a certificate automatically via [Let's Encrypt](https://letsencrypt.org/), set `tls_letsencrypt_hostname` to the desired certificate hostname. This name must resolve to the IP address(es) headscale is reachable on (i.e., it must correspond to the `server_url` configuration parameter). The certificate and Let's Encrypt account credentials will be stored in the directory configured in `tls_letsencrypt_cache_dir`. If the path is relative, it will be interpreted as relative to the directory the configuration file was read from.
```yaml title="config.yaml"
tls_letsencrypt_hostname: ""
tls_letsencrypt_listen: ":http"
tls_letsencrypt_cache_dir: ".cache"
tls_letsencrypt_challenge_type: HTTP-01
```
### Challenge types
Headscale only supports two values for `tls_letsencrypt_challenge_type`: `HTTP-01` (default) and `TLS-ALPN-01`.
#### HTTP-01
For `HTTP-01`, headscale must be reachable on port 80 for the Let's Encrypt automated validation, in addition to whatever port is configured in `listen_addr`. By default, headscale listens on port 80 on all local IPs for Let's Encrypt automated validation.
If you need to change the ip and/or port used by headscale for the Let's Encrypt validation process, set `tls_letsencrypt_listen` to the appropriate value. This can be handy if you are running headscale as a non-root user (or can't run `setcap`). Keep in mind, however, that Let's Encrypt will _only_ connect to port 80 for the validation callback, so if you change `tls_letsencrypt_listen` you will also need to configure something else (e.g. a firewall rule) to forward the traffic from port 80 to the ip:port combination specified in `tls_letsencrypt_listen`.
#### TLS-ALPN-01
For `TLS-ALPN-01`, headscale listens on the ip:port combination defined in `listen_addr`. Let's Encrypt will _only_ connect to port 443 for the validation callback, so if `listen_addr` is not set to port 443, something else (e.g. a firewall rule) will be required to forward the traffic from port 443 to the ip:port combination specified in `listen_addr`.
### Technical description
Headscale uses [autocert](https://pkg.go.dev/golang.org/x/crypto/acme/autocert), a Golang library providing [ACME protocol](https://en.wikipedia.org/wiki/Automatic_Certificate_Management_Environment) verification, to facilitate certificate renewals via [Let's Encrypt](https://letsencrypt.org/about/). Certificates will be renewed automatically, and the following can be expected:
- Certificates provided from Let's Encrypt have a validity of 3 months from date issued.
- Renewals are only attempted by headscale when 30 days or less remains until certificate expiry.
- Renewal attempts by autocert are triggered at a random interval of 30-60 minutes.
- No log output is generated when renewals are skipped, or successful.
#### Checking certificate expiry
If you want to validate that certificate renewal completed successfully, this can be done either manually, or through external monitoring software. Two examples of doing this manually:
1. Open the URL for your headscale server in your browser of choice, and manually inspecting the expiry date of the certificate you receive.
1. Or, check remotely from CLI using `openssl`:
```console
$ openssl s_client -servername [hostname] -connect [hostname]:443 | openssl x509 -noout -dates
(...)
notBefore=Feb 8 09:48:26 2024 GMT
notAfter=May 8 09:48:25 2024 GMT
```
#### Log output from the autocert library
As these log lines are from the autocert library, they are not strictly generated by headscale itself.
```plaintext
acme/autocert: missing server name
```
Likely caused by an incoming connection that does not specify a hostname, for example a `curl` request directly against the IP of the server, or an unexpected hostname.
```plaintext
acme/autocert: host "[foo]" not configured in HostWhitelist
```
Similarly to the above, this likely indicates an invalid incoming request for an incorrect hostname, commonly just the IP itself.
The source code for autocert can be found [here](https://cs.opensource.google/go/x/crypto/+/refs/tags/v0.19.0:acme/autocert/autocert.go)

# Running headscale in a container
!!! warning "Community documentation"
This page is not actively maintained by the headscale authors and is
written by community members. It is _not_ verified by headscale developers.
**It might be outdated and it might miss necessary steps**.
This documentation has the goal of showing a user how-to set up and run headscale in a container. A container runtime
such as [Docker](https://www.docker.com) or [Podman](https://podman.io) is required. The container image can be found on
[Docker Hub](https://hub.docker.com/r/headscale/headscale) and [GitHub Container
Registry](https://github.com/juanfont/headscale/pkgs/container/headscale). The container image URLs are:
- [Docker Hub](https://hub.docker.com/r/headscale/headscale): `docker.io/headscale/headscale:<VERSION>`
- [GitHub Container Registry](https://github.com/juanfont/headscale/pkgs/container/headscale):
`ghcr.io/juanfont/headscale:<VERSION>`
## Configure and run headscale
1. Create a directory on the container host to store headscale's [configuration](../../ref/configuration.md) and the [SQLite](https://www.sqlite.org/) database:
```shell
mkdir -p ./headscale/{config,lib}
cd ./headscale
```
1. Download the example configuration for your chosen version and save it as: `$(pwd)/config/config.yaml`. Adjust the
configuration to suit your local environment. See [Configuration](../../ref/configuration.md) for details.
1. Start headscale from within the previously created `./headscale` directory:
```shell
docker run \
--name headscale \
--detach \
--read-only \
--tmpfs /var/run/headscale \
--volume "$(pwd)/config:/etc/headscale:ro" \
--volume "$(pwd)/lib:/var/lib/headscale" \
--publish 127.0.0.1:8080:8080 \
--publish 127.0.0.1:9090:9090 \
--health-cmd "CMD headscale health" \
docker.io/headscale/headscale:<VERSION> \
serve
```
Note: use `0.0.0.0:8080:8080` instead of `127.0.0.1:8080:8080` if you want to expose the container externally.
This command mounts the local directories inside the container, forwards port 8080 and 9090 out of the container so
the headscale instance becomes available and then detaches so headscale runs in the background.
A similar configuration for `docker-compose`:
```yaml title="docker-compose.yaml"
services:
headscale:
image: docker.io/headscale/headscale:<VERSION>
restart: unless-stopped
container_name: headscale
read_only: true
tmpfs:
- /var/run/headscale
ports:
- "127.0.0.1:8080:8080"
- "127.0.0.1:9090:9090"
volumes:
# Please set <HEADSCALE_PATH> to the absolute path
# of the previously created headscale directory.
- <HEADSCALE_PATH>/config:/etc/headscale:ro
- <HEADSCALE_PATH>/lib:/var/lib/headscale
command: serve
healthcheck:
test: ["CMD", "headscale", "health"]
```
1. Verify headscale is running:
Follow the container logs:
```shell
docker logs --follow headscale
```
Verify running containers:
```shell
docker ps
```
Verify headscale is available:
```shell
curl http://127.0.0.1:8080/health
```
Continue on the [getting started page](../../usage/getting-started.md) to register your first machine.
## Debugging headscale running in Docker
The Headscale container image is based on a "distroless" image that does not contain a shell or any other debug tools. If you need to debug headscale running in the Docker container, you can use the `-debug` variant, for example `docker.io/headscale/headscale:x.x.x-debug`.
### Running the debug Docker container
To run the debug Docker container, use the exact same commands as above, but replace `docker.io/headscale/headscale:x.x.x` with `docker.io/headscale/headscale:x.x.x-debug` (`x.x.x` is the version of headscale). The two containers are compatible with each other, so you can alternate between them.
### Executing commands in the debug container
The default command in the debug container is to run `headscale`, which is located at `/ko-app/headscale` inside the container.
Additionally, the debug container includes a minimalist Busybox shell.
To launch a shell in the container, use:
```shell
docker run -it docker.io/headscale/headscale:x.x.x-debug sh
```
You can also execute commands directly, such as `ls /ko-app` in this example:
```shell
docker run docker.io/headscale/headscale:x.x.x-debug ls /ko-app
```
Using `docker exec -it` allows you to run commands in an existing container.

# Official releases
Official releases for headscale are available as binaries for various platforms and DEB packages for Debian and Ubuntu.
Both are available on the [GitHub releases page](https://github.com/juanfont/headscale/releases).
## Using packages for Debian/Ubuntu (recommended)
It is recommended to use our DEB packages to install headscale on a Debian based system as those packages configure a
local user to run headscale, provide a default configuration and ship with a systemd service file. Supported
distributions are Ubuntu 22.04 or newer, Debian 12 or newer.
1. Download the [latest headscale package](https://github.com/juanfont/headscale/releases/latest) for your platform (`.deb` for Ubuntu and Debian).
```shell
HEADSCALE_VERSION="" # See above URL for latest version, e.g. "X.Y.Z" (NOTE: do not add the "v" prefix!)
HEADSCALE_ARCH="" # Your system architecture, e.g. "amd64"
wget --output-document=headscale.deb \
"https://github.com/juanfont/headscale/releases/download/v${HEADSCALE_VERSION}/headscale_${HEADSCALE_VERSION}_linux_${HEADSCALE_ARCH}.deb"
```
1. Install headscale:
```shell
sudo apt install ./headscale.deb
```
1. [Configure headscale by editing the configuration file](../../ref/configuration.md):
```shell
sudo nano /etc/headscale/config.yaml
```
1. Enable and start the headscale service:
```shell
sudo systemctl enable --now headscale
```
1. Verify that headscale is running as intended:
```shell
sudo systemctl status headscale
```
Continue on the [getting started page](../../usage/getting-started.md) to register your first machine.
## Using standalone binaries (advanced)
!!! warning "Advanced"
This installation method is considered advanced as one needs to take care of the local user and the systemd
service themselves. If possible, use the [DEB packages](#using-packages-for-debianubuntu-recommended) or a
[community package](./community.md) instead.
This section describes the installation of headscale according to the [Requirements and
assumptions](../requirements.md#assumptions). Headscale is run by a dedicated local user and the service itself is
managed by systemd.
1. Download the latest [`headscale` binary from GitHub's release page](https://github.com/juanfont/headscale/releases):
```shell
sudo wget --output-document=/usr/bin/headscale \
https://github.com/juanfont/headscale/releases/download/v<HEADSCALE VERSION>/headscale_<HEADSCALE VERSION>_linux_<ARCH>
```
1. Make `headscale` executable:
```shell
sudo chmod +x /usr/bin/headscale
```
1. Add a dedicated local user to run headscale:
```shell
sudo useradd \
--create-home \
--home-dir /var/lib/headscale/ \
--system \
--user-group \
--shell /usr/sbin/nologin \
headscale
```
1. Download the example configuration for your chosen version and save it as: `/etc/headscale/config.yaml`. Adjust the
configuration to suit your local environment. See [Configuration](../../ref/configuration.md) for details.
```shell
sudo mkdir -p /etc/headscale
sudo nano /etc/headscale/config.yaml
```
1. Copy [headscale's systemd service file](https://github.com/juanfont/headscale/blob/main/packaging/systemd/headscale.service)
to `/etc/systemd/system/headscale.service` and adjust it to suit your local setup. The following parameters likely need
to be modified: `ExecStart`, `WorkingDirectory`, `ReadWritePaths`.
1. In `/etc/headscale/config.yaml`, override the default `headscale` unix socket with a path that is writable by the
`headscale` user or group:
```yaml title="config.yaml"
unix_socket: /var/run/headscale/headscale.sock
```
1. Reload systemd to load the new configuration file:
```shell
systemctl daemon-reload
```
1. Enable and start the new headscale service:
```shell
systemctl enable --now headscale
```
1. Verify that headscale is running as intended:
```shell
systemctl status headscale
```
Continue on the [getting started page](../../usage/getting-started.md) to register your first machine.

# Build from source
!!! warning "Community documentation"
This page is not actively maintained by the headscale authors and is
written by community members. It is _not_ verified by headscale developers.
**It might be outdated and it might miss necessary steps**.
Headscale can be built from source using the latest version of [Go](https://golang.org) and [Buf](https://buf.build)
(Protobuf generator). See the [Contributing section in the GitHub
README](https://github.com/juanfont/headscale#contributing) for more information.
## OpenBSD
### Install from source
```shell
# Install prerequisites
pkg_add go git
git clone https://github.com/juanfont/headscale.git
cd headscale
# optionally checkout a release
# option a. you can find official release at https://github.com/juanfont/headscale/releases/latest
# option b. get latest tag, this may be a beta release
latestTag=$(git describe --tags `git rev-list --tags --max-count=1`)
git checkout $latestTag

# copy it to /usr/local/sbin
cp headscale /usr/local/sbin
```
### Install from source via cross compile
```shell
# Install prerequisites
# 1. go v1.20+: headscale newer than 0.21 needs go 1.20+ to compile
# 2. gmake: Makefile in the headscale repo is written in GNU make syntax
git clone https://github.com/juanfont/headscale.git
cd headscale
# optionally checkout a release
# option a. you can find official release at https://github.com/juanfont/headscale/releases/latest
# option b. get latest tag, this may be a beta release
latestTag=$(git describe --tags `git rev-list --tags --max-count=1`)
git checkout $latestTag
make build GOOS=openbsd
# copy headscale to openbsd machine and put it in /usr/local/sbin
```
================================================
FILE: docs/setup/requirements.md
================================================
# Requirements
Headscale should just work as long as the following requirements are met:
- A server with a public IP address for headscale. A dual-stack setup with a public IPv4 and a public IPv6 address is
recommended.
- Headscale is served via HTTPS on port 443[^1] and [may use additional ports](#ports-in-use).
- A reasonably modern Linux or BSD based operating system.
- A dedicated local user account to run headscale.
- A little bit of command line knowledge to configure and operate headscale.
## Ports in use
The ports in use vary with the intended scenario and enabled features. Some of the listed ports may be changed via the
[configuration file](../ref/configuration.md) but we recommend to stick with the default values.
- tcp/80
- Expose publicly: yes
- HTTP, used by Let's Encrypt to verify ownership via the HTTP-01 challenge.
- Only required if the built-in Let's Enrypt client with the HTTP-01 challenge is used. See [TLS](../ref/tls.md) for
details.
- tcp/443
- Expose publicly: yes
- HTTPS, required to make Headscale available to Tailscale clients[^1]
- Required if the [embedded DERP server](../ref/derp.md) is enabled
- udp/3478
- Expose publicly: yes
- STUN, required if the [embedded DERP server](../ref/derp.md) is enabled
- tcp/50443
- Expose publicly: yes
- Only required if the gRPC interface is used to [remote-control Headscale](../ref/api.md#grpc).
- tcp/9090
- Expose publicly: no
- [Metrics and debug endpoint](../ref/debug.md#metrics-and-debug-endpoint)
## Assumptions
The headscale documentation and the provided examples are written with a few assumptions in mind:
- Headscale is running as system service via a dedicated local user `headscale`.
- The [configuration](../ref/configuration.md) is loaded from `/etc/headscale/config.yaml`.
- SQLite is used as database.
- The data directory for headscale (used for private keys, ACLs, SQLite database, …) is located in `/var/lib/headscale`.
- URLs and values that need to be replaced by the user are either denoted as `<VALUE_TO_CHANGE>` or use placeholder
values such as `headscale.example.com`.
Please adjust to your local environment accordingly.
[^1]: The Tailscale client assumes HTTPS on port 443 in certain situations. Serving headscale either via HTTP or via
HTTPS on a port other than 443 is possible but sticking with HTTPS on port 443 is strongly recommended for
production setups. See [issue 2164](https://github.com/juanfont/headscale/issues/2164) for more information.
================================================
FILE: docs/setup/upgrade.md
================================================
# Upgrade an existing installation
!!! tip "Required update path"
Its required to update from one stable version to the next (e.g. 0.26.0 → 0.27.1 → 0.28.0) without skipping minor
versions in between. You should always pick the latest available patch release.
Update an existing Headscale installation to a new version:
- Read the announcement on the [GitHub releases](https://github.com/juanfont/headscale/releases) page for the new
version. It lists the changes of the release along with possible breaking changes and version-specific upgrade
instructions.
- Stop Headscale
- **[Create a backup of your installation](#backup)**
- Update Headscale to the new version, preferably by following the same installation method.
- Compare and update the [configuration](../ref/configuration.md) file.
- Start Headscale
## Backup
Headscale applies database migrations during upgrades and we highly recommend to create a backup of your database before
upgrading. A full backup of Headscale depends on your individual setup, but below are some typical setup scenarios.
=== "Standard installation"
A installation that follows our [official releases](install/official.md) setup guide uses the following paths:
- [Configuration file](../ref/configuration.md): `/etc/headscale/config.yaml`
- Data directory: `/var/lib/headscale`
- SQLite as database: `/var/lib/headscale/db.sqlite`
```console
TIMESTAMP=$(date +%Y%m%d%H%M%S)
cp -aR /etc/headscale /etc/headscale.backup-$TIMESTAMP
cp -aR /var/lib/headscale /var/lib/headscale.backup-$TIMESTAMP
```
=== "Container"
A installation that follows our [container](install/container.md) setup guide uses a single source volume directory
that contains the configuration file, data directory and the SQLite database.
```console
cp -aR /path/to/headscale /path/to/headscale.backup-$(date +%Y%m%d%H%M%S)
```
=== "PostgreSQL"
Please follow PostgreSQL's [Backup and Restore](https://www.postgresql.org/docs/current/backup.html) documentation
to create a backup of your PostgreSQL database.

all the time, please enable "Unattended mode":
- Click on the Tailscale tray icon and select `Preferences`
- Enable `Run unattended`
- Confirm the "Unattended mode" message
See also [Keep Tailscale running when I'm not logged in to my computer](https://tailscale.com/kb/1088/run-unattended)
### Failing node registration
If you are seeing repeated messages like:
```
[GIN] 2022/02/10 - 16:39:34 | 200 | 1.105306ms | 127.0.0.1 | POST "/machine/redacted"
```
in your headscale output, turn on `DEBUG` logging and look for:
```
2022-02-11T00:59:29Z DBG Machine registration has expired. Sending a authurl to register machine=redacted
```
This typically means that the registry keys above was not set appropriately.
To reset and try again, it is important to do the following:
1. Shut down the Tailscale service (or the client running in the tray)
1. Delete Tailscale Application data folder, located at `C:\Users\<USERNAME>\AppData\Local\Tailscale` and try to connect again.
1. Ensure the Windows node is deleted from headscale (to ensure fresh setup)
1. Start Tailscale on the Windows machine and retry the login.
================================================
FILE: docs/usage/getting-started.md
================================================
# Getting started
This page helps you get started with headscale and provides a few usage examples for the headscale command line tool
`headscale`.
!!! note "Prerequisites"
- Headscale is installed and running as system service. Read the [setup section](../setup/requirements.md) for
installation instructions.
- The configuration file exists and is adjusted to suit your environment, see
[Configuration](../ref/configuration.md) for details.
- Headscale is reachable from the Internet. Verify this by visiting the health endpoint:
https://headscale.example.com/health
- The Tailscale client is installed, see [Client and operating system support](../about/clients.md) for more
information.
## Getting help
The `headscale` command line tool provides built-in help. To show available commands along with their arguments and
options, run:
=== "Native"
```shell
# Show help
headscale help
# Show help for a specific command
headscale <COMMAND> --help
```
=== "Container"
```shell
# Show help
docker exec -it headscale \
headscale help
# Show help for a specific command
docker exec -it headscale \
headscale <COMMAND> --help
```
!!! note "Manage headscale from another local user"
By default only the user `headscale` or `root` will have the necessary permissions to access the unix socket
(`/var/run/headscale/headscale.sock`) that is used to communicate with the service. In order to be able to
communicate with the headscale service you have to make sure the unix socket is accessible by the user that runs
the commands. In general you can achieve this by any of the following methods:
- using `sudo`
- run the commands as user `headscale`
- add your user to the `headscale` group
To verify you can run the following command using your preferred method:
```shell
headscale users list
```
## Manage headscale users
In headscale, a node (also known as machine or device) is [typically assigned to a headscale
user](../ref/registration.md#identity-model). Such a headscale user may have many nodes assigned to them and can be
managed with the `headscale users` command. Invoke the built-in help for more information: `headscale users --help`.
### Create a headscale user
=== "Native"
```shell
headscale users create <USER>
```
=== "Container"
```shell
docker exec -it headscale \
headscale users create <USER>
```
### List existing headscale users
=== "Native"
```shell
headscale users list
```
=== "Container"
```shell
docker exec -it headscale \
headscale users list
```
## Register a node
One has to [register a node](../ref/registration.md) first to use headscale as coordination server with Tailscale. The
following examples work for the Tailscale client on Linux/BSD operating systems. Alternatively, follow the instructions
to connect [Android](connect/android.md), [Apple](connect/apple.md) or [Windows](connect/windows.md) devices. Read
[registration methods](../ref/registration.md) for an overview of available registration methods.
### [Web authentication](../ref/registration.md#web-authentication)
On a client machine, run the `tailscale up` command and provide the FQDN of your headscale instance as argument:
```shell
tailscale up --login-server <YOUR_HEADSCALE_URL>
```
Usually, a browser window with further instructions is opened. This page explains how to complete the registration on
your headscale server and it also prints the Auth ID required to approve the node:
=== "Native"
```shell
headscale auth register --user <USER> --auth-id <AUTH_ID>
```
=== "Container"
```shell
docker exec -it headscale \
headscale auth register --user <USER> --auth-id <AUTH_ID>
```
### [Pre authenticated key](../ref/registration.md#pre-authenticated-key)
It is also possible to generate a preauthkey and register a node non-interactively. First, generate a preauthkey on the
headscale instance. By default, the key is valid for one hour and can only be used once (see `headscale preauthkeys --help` for other options):
=== "Native"
```shell
headscale preauthkeys create --user <USER_ID>
```
=== "Container"
```shell
docker exec -it headscale \
headscale preauthkeys create --user <USER_ID>
```
The command returns the preauthkey on success which is used to connect a node to the headscale instance via the
`tailscale up` command:
```shell
tailscale up --login-server <YOUR_HEADSCALE_URL> --authkey <YOUR_AUTH_KEY>
```

-- - The tags column is still named forced_tags
--
-- Test scenarios:
-- 1. Node with RequestTags that user is authorized for (should be migrated)
-- 2. Node with RequestTags that user is NOT authorized for (should be rejected)
-- 3. Node with existing forced_tags that should be preserved
-- 4. Node with RequestTags that overlap with existing tags (no duplicates)
-- 5. Node without RequestTags (should be unchanged)
-- 6. Node with RequestTags via group membership (should be migrated)

// - Rule 2 (subnet -> member): All members get filter with all member IPs in DstPorts
// - Exit nodes do NOT get filters
//

// - All members get filters (rule 2 distribution to all)
// - DstPorts only contains self IP, not all member IPs

// I6: Dual-stack node - targeting both IPv4 and IPv6 subnets
//
// TAILSCALE BEHAVIOR:
// - Only subnet-router (10.33.0.0/16) and big-router (10.0.0.0/8) get IPv4 filter
// - No node has fd00:1::/64 route, so no node gets IPv6 filter
// - Exit nodes do NOT get filters for specific subnet destinations
// - Multiple rules with same SrcIPs kept as separate rules
//
// HEADSCALE BEHAVIOR:
// - Exit nodes get filters (exit route covers both subnets)
// - Rules with same SrcIPs and IPProto are MERGED into single rule
// with combined DstPorts
// - No node owns fd00:1::/64, but exit nodes cover it via ::/0
//
// ROOT CAUSE:
// 1. Exit route coverage: 0.0.0.0/0 and ::/0 cover all subnets
// 2. Filter rule merging: Headscale merges rules with identical SrcIPs/IPProto
//
// FIX REQUIRED:
// Exclude exit nodes from specific subnet destinations.

// Scenario:
// 1. Start a real long-poll session for one node.
// 2. Block the first map write long enough for the session to stop draining
// its buffered map-response channel.
// 3. While that write is blocked, queue enough updates to fill the buffered
// channel and make the next batcher send hit the stale-send timeout.
// 4. That stale-send path removes the session from the batcher, so without an
// explicit teardown hook the old serveLongPoll goroutine would stay alive
// but stop receiving future updates.
// 5. Release the blocked write and verify the batcher-side stop signal makes
// that stale session exit instead of lingering as an orphaned goroutine.
