# Guacamole appliance setup script

#######################################################################################################################
# To install the latest code snapshot:
# wget https://raw.githubusercontent.com/itiligent/Guacamole-Install/main/1-setup.sh && chmod +x 1-setup.sh && ./1-setup.sh
# 1-setup.sh is a central script that manages all inputs, options and sequences other included 'install' scripts.
# 2-install-guacamole downloads Guacamole source and exectutes all Guacamole's build instructions.
# 3-install-nginx.sh automatically installs and configures Nginx to work as an http port 80 front end to Guacamole.
# 4a-install-tls-self-signed-nginx.sh sets up the new Nginx/Guacamole front end with self signed TLS certificates.
# 4b-install-tls-letsencrypt-nginx.sh sets up Nginx with public TLS certificates from LetsEncrypt.
# Scripts with "add" in their name can be run post install to add optional features not included in the main install.
# For troubleshooting check logs or place Guacamole in debug mode:
# tail -f /var/log/syslog /var/log/tomcat*/*.out guac-setup/guacamole_setup.log
# sudo systemctl stop guacd && sudo /usr/local/sbin/guacd -L debug -f

FILE: ACTIVE-DIRECTORY-HOW-TO.md
================================================
## Integrating Guacamole With Active Directory
### :arrows_clockwise: **Step 1: Ensure two-way LDAP traffic is available to the Guacamole application server**
- If Guacamole is operating in a separate network from your Active Directory Servers, allow TCP 389 between all Guacamole application servers and all Active Directory Domain Controllers nominated in the config script settings below.
### :key: **Step 2: Establish the required accounts to bind with Active Directory**
- An account with only **Domain Users** rights is sufficient for Guacamole to read and bind with Active Directory.
- a. In the Guacamole application, create a new Guacamole account with full admin rights to the Guacamole application, e.g. `guacbind-ad`, and assign it an appropriately strong password. (Then log in with this new account and disable the default guacadmin account)
- b. Create a new Active Directory domain account with EXACTLY THE SAME NAME as the new full admin account named above, only this time assign a DIFFERENT strong password than what was used above.
### :pencil: **Step 3: Edit the provided configuration script to reflect your specific Active Directory environment**
Below is the EXACT format to follow in editing the `$USER_HOME_DIR/guac-setup/add-ldap-auth-guacamole.sh` script. Be careful not to introduce new lines, spaces at the ends of lines or carriage returns. Anything outside of this format will cause the LDAP auth extension to fail. You have been warned!
```
ldap-hostname: dc1.yourdomain.com dc2.yourdomain.com dc3.yourdomain.com
ldap-port: 389
ldap-username-attribute: sAMAccountName
ldap-encryption-method: none
ldap-search-bind-dn: guacbind-ad@yourdomain.com
ldap-search-bind-password: guacbind-ad-password
ldap-config-base-dn: dc=yourdomain,dc=com
ldap-user-base-dn: OU=SomeOU,DC=yourdomain,DC=com
ldap-user-search-filter:(objectClass=user)(!(objectCategory=computer))
ldap-max-search-results:200
mysql-auto-create-accounts: true
```
**Edit only the following values from the above example to suit your environment, then save the add-ldap-auth-guacamole.sh script:**
```
ldap-hostname:
ldap-search-bind-dn:
ldap-search-bind-password:
ldap-config-base-dn:
ldap-user-base-dn:
mysql-auto-create-accounts: true
ldap-max-search-results:200
```
- **Important note on `ldap-user-base-dn:`** This value sets a position in the directory as a relative root to search within. All Guacamole users to be authenticated by Active Directory must be placed in a lower position within the directory tree than this value. This line can be added multiple times to more efficiently search across multiple branches of a directory tree.
- **Important note on `ldap-max-search-results:`** Yes, there is no space before the default `:200` value. In larger environments managing the directory efficiently requires that we don't query every object in the tree for every user lookup. You may need to adjust this number depending on the number of objects in the above relative root search path.
- **Important note on `mysql-auto-create-accounts:`** This line is optional and can be deleted if using Active Directory authentication without Guacamole's implementation of MFA. This line ensures that all Active Directory user accounts will have a matching user account created in the Guacamole database at thier first Guacmaole logon with thier AD accout. Only if Gucamole's MFA feature is to be provisioned is a local Guacamole account required, and automating this step can aid MFA deployment. If you want to provision Guacamole MFA access to just a limited selection of Active Diretory users, you may remove this line and manually create the passwordless Guacamole database local account pairings as needed. [See below for more.](https://github.com/itiligent/Guacamole-Install/blob/main/ACTIVE-DIRECTORY-HOW-TO.md#busts_in_silhouette-manually-creating-and-configuring-new-guacamole-users-for-active-directory-authentication-with-mfa)
#### If your AD has TLS implemented via a self signed certificate you must also apply the extra TLS tasks A to E below, else skip to Step 4 ... For more info see [#18](https://github.com/itiligent/Guacamole-Install/issues/18)
TLS task A. Adjust this line in the above template for add-ldap-auth-guacamole.sh (Values can be none, ssl or stattls)
```
ldap-encryption-method: starttls
```
TLS task B. Next, you must obtain your AD TLS cert.
```
openssl s_client -connect X.X.X.X:389 \
-starttls ldap \
-showcerts < /dev/null | \
openssl x509 -text | \
sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'
```
TLS task C. Copy the certificate contents from -----BEGIN CERTIFICATE----- to -----END CERTIFICATE----- and paste this into a file (e.g. adcert.pem as per below)
```
sudo nano /etc/ssl/certs/adcert.pem # then paste certificate output
```
TLS task D. Now import the AD cert file into the Java keystore
```
sudo keytool -importcert -alias adcert \
-file /etc/ssl/certs/adcert.pem \
-keystore /usr/lib/jvm/java-11-openjdk-amd64/lib/security/cacerts \
-storepass changeit \
-noprompt
```
TLS task E. Restart Apache Tomcat
````
TOMCAT=$(ls /etc/ | grep tomcat) && sudo systemctl restart ${TOMCAT}
````
### :computer: **Step 4: Run the (now customised) LDAP configuration script**
```shell
sudo $USER_HOME_DIR/guac-setup/add-ldap-auth-guacamole.sh
```
### :door: **Step 5: Log on to Guacamole with the new guacbind-ad account**
- When logging in to Guacamole as the new Active Directory account and password created above, that domain user is passed through to Guacamole as both a Guacamole admin and a Domain User. If all is working correctly, all the users located below the directory tree position set in **ldap-user-base-dn** will be listed under **Settings | Users** of the Guacamole management console.
### :busts_in_silhouette: **Manually creating and configuring new Guacamole users for Active Directory authentication with MFA.**
- If not using the **mysql-auto-create-accounts** directive, manually re-create the exact user account names in Guacamole as those in the directory that you wish to give specific local adminstrative permissions and/or provision Guacamole's MFA access. **DO NOT configure a Guacamole password for any users that will be exclusively authenticating via Active directory**. Guacamole database local user accounts without a password are first given an MFA challenge by the local Guacamole application (Only where the local passwordless Guacamole account is configured for MFA) and then will be brokered to Active Directory for their Kerberos authentication challenge. Guacamole database local user accounts that are given passwords in Guacamole will always refer to the local database account for authentication, never Active Directory. This design allows for a matrix of local, domain, MFA & non-MFA access use cases to be deployed.
### :key: **Logging in using Gucamole local vs. domain guacbind-ad account**
- As described above, logging on with the Guacamole admin user password will authenticate with the local Guacamole admin account, conversely if the Guacamole admin domain account password is given, the domain account is authenticated via Active Directory and then passed through as authorized to administer Guacamole. It may sometimes be necessary to log on with the local Guacamole admin account to manage some application functions, but be aware that when doing so you will not be able to view and search the user list from Active Directory. Only when logged on with the domain version of the Guacamole admin account can domain user permissions to various Guacamole sessions and objects be delegated and managed.
### :gear: **Creating a quasi Single Sign-On user experience for Windows RDP access**
- Create a Global Security domain group (e.g., Guac_Users) and populate it with selected domain users as required.
- Now add this new security group to the built-in “Remote Desktop Users” domain group.
- Next, for each connection profile you wish to create the SSO experience and behavior, _parameter_ _tokens_ must be used in place of hard-coded usernames and password values as follows...
- Add the parameter token `${GUAC_USERNAME}` to the Username field for each connection profile
- Add the parameter token `${GUAC_PASSWORD}` to the Password field for each connection profile
- If the user has been given directory rights to the Guacamole session object, Guacamole will first authenticate the user to the Guacamole application (via a brokered Active Directory challenge) and then seamlessly pass the user's same domain credentials through to the Guacamole remote desktop session, thus avoiding any further remote desktop authentication prompts.
- For more info on other dynamic connection settings see [Guacamole Documentation](https://guacamole.apache.org/doc/gug/configuring-guacamole.html#parameter-tokens)
- Additional extensions are required for full SSO, but because centralised authentication / authorisation extensions require a bespoke approach to service providers and login behaviors, the SSO features are currently beyond the scope of this project. Here's some links for info on configuring [SAML](https://guacamole.apache.org/doc/gug/saml-auth.html#) and [OpenID Connect](https://guacamole.apache.org/doc/gug/openid-auth.html)

================================================
GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU Affero General Public License is a free, copyleft license for
software and other kinds of works, specifically designed to ensure
cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
our General Public Licenses are intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
Developers that use our General Public Licenses protect your rights
with two steps: (1) assert copyright on the software, and (2) offer
you this License which gives you legal permission to copy, distribute
and/or modify the software.
A secondary benefit of defending all users' freedom is that
improvements made in alternate versions of the program, if they
receive widespread use, become available for other developers to
incorporate. Many developers of free software are heartened and
encouraged by the resulting cooperation. However, in the case of
software used on network servers, this result may fail to come about.
The GNU General Public License permits making a modified version and
letting the public access it on a server without ever releasing its
source code to the public.
The GNU Affero General Public License is designed specifically to
ensure that, in such cases, the modified source code becomes available
to the community. It requires the operator of a network server to
provide the source code of the modified version running there to the
users of that server. Therefore, public use of a modified version, on
a publicly accessible server, gives the public access to the source
code of the modified version.
An older license, called the Affero General Public License and
published by Affero, was designed to accomplish similar goals. This is
a different license, not a version of the Affero GPL, but Affero has
released a new version of the Affero GPL which permits relicensing under
this license.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the
Program, your modified version must prominently offer all users
interacting with it remotely through a computer network (if your version
supports such interaction) an opportunity to receive the Corresponding
Source of your version by providing access to the Corresponding Source
from a network server at no charge, through some standard or customary
means of facilitating copying of software. This Corresponding Source
shall include the Corresponding Source for any work covered by version 3
of the GNU General Public License that is incorporated pursuant to the
following paragraph.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the work with which it is combined will remain governed by version
3 of the GNU General Public License.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU Affero General Public License from time to time. Such new versions
will be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU Affero General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU Affero General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU Affero General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU Affero General Public License as published
by the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU Affero General Public License for more details.
You should have received a copy of the GNU Affero General Public License
along with this program. If not, see <https://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If your software can interact with users remotely through a computer
network, you should also make sure that it provides a way for users to
get its source. For example, if your program is a web application, its
interface could display a "Source" link that leads users to an archive
of the code. There are many ways you could offer source, and different
solutions will be better for different programs; see section 13 for the
specific requirements.
You should also get your employer (if you work as a programmer) or school,

</p>
## Introduction
#### v1.6.0 is working. Issues and notes are tracked in https://github.com/itiligent/Easy-Guacamole-Installer/issues/78
This install script automatically sets up a Guacamole jump-host with optional for TLS reverse proxy (self-signed or Let's Encrypt), Active Directory integration, multi-factor authentication, Quick Connect & History Recording Storage UI enhancements. Other options also include a custom UI dark themed template, auto database backups, email alerts and internal hardening options including fail2ban for defence against brute force attacks. There is also facility for tiered enterprise deployment similar to [Amazon's Guacamole Bastion Cluster](http://netcubed-ami.s3-website-us-east-1.amazonaws.com/guaws/v2.3.1/cluster/).
## Automatic Installation
🚀 Move to you your home directory, paste the below link, then follow the prompts (**do NOT run as root, the script will prompt for sudo**):
```shell
wget https://raw.githubusercontent.com/itiligent/Guacamole-Install/main/1-setup.sh && chmod +x 1-setup.sh && ./1-setup.sh
```
---
## Prerequisites
📋 **You will need:**
- **Supported OS: Debian 12 or 13** | **Ubuntu LTS 22.x or 24.x** | **Raspbian**
- **1 CPU core + 2GB RAM for every 25 users (plus minimum RAM & disk space for your selected OS).**
- **Open TCP ports: 22, 80, and 443 (no other services using 80, 8080 & 443)**
- **For both TLS reverse proxy options you will need a PRIVATE DNS record for the internal proxy site, and an additional PUBLIC DNS record for the Let's Encrypt option.**
- **Sudo & wget packages installed**
- **The user running `1-setup.sh` must have sudo permissions.**
---
## Setup Script Menu
🔧 **The main `1-setup.sh` script guides the installation with the following steps:**
1. Setup the system hostname & local DNS name (Local DNS must be consistent for TLS proxy).
2. Select either a local MySQL install or use a pre-existing local or remote MySQL instance.
3. Pick an authentication extension: DUO, TOTP, LDAP/Active Directory, or none.
4. Select optional console features: Quick Connect & History Recorded Storage UI integrations.
5. Select the Guacamole front end: Nginx reverse proxy (HTTP or HTTPS) or use the native Guacamole interface on port 8080.
- If you opt to install Nginx with self-signed TLS:
- New server & client browser certificates are saved to `$HOME/guac-setup/tls-certs/[date-time]/`.
- Optionally follow on-screen instructions for client certificate import to avoid https browser warnings.
---
## Customising The Build
⚙️ **To customise the many available script options:**
- Exit `1-setup.sh` at the first prompt.
- All configurable script options are shown under **Silent setup options** at the start of `1-setup.sh`.
- Certain combinations of the **Silent setup options** will allow for a fully unattended install supporting mass deployment or highly customised docker builds.
- Re-run your edited script locally after making changes (do not re-run the automatic install web link - see below).
**Other custom install notes:**
- **Caution:** Re-running the auto-installer link re-downloads the suite of scripts which will overwrite any custom script edits. You must run 1-setup.sh LOCALLY after editing. If any child scripts are edited, their corresponding download links in 1-setup.sh script must also be commented out.
- Upgrade scripts are **automatically customised with your specifc installation settings** for consistent future updates.
- Nginx reverse proxy is configured to default to at least TLS 1.2. For ancient systems, see commented sections of the `/etc/nginx/nginx.conf` file after install.
- A daily MySQL backup job is automatically configured under the script owner's crontab.
- The Quick Connect option brings some extra security implications, be aware of potential risks in your environment.
**Post-install manual hardening options:**
- `add-fail2ban.sh`: Adds a lockdown policy for Guacamole to guard against brute force password attacks.
- `add-tls-guac-daemon.sh`: Wraps internal traffic between the guac server & guac application in TLS.
- `add-auth-ldap.sh`: Template script for simplified Active Directory integration.
- `add-smtp-relay-o365.sh`: Template script for email alert integration with MSO65 (BYO app password).
---
## Branding The Guacamole UI Theme
🎨 **Follow the theme and branding instructions** [here](https://github.com/itiligent/Guacamole-Install/tree/main/guac-custom-theme-builder). To revert to the default theme, simply delete the branding.jar file from `/etc/guacamole/extensions`, clear your browser cache and restart.
---
## Managing Self-Signed TLS Certs With Nginx
**To renew self-signed certificates or change the reverse proxy local DNS name/IP address:**
- Re-run `4a-install-tls-self-signed-nginx.sh` to create a new Nginx certificate (new browser client certificates will also be created for re-import). Always clear your browser cache after changing certificates.
---
## Active Directory Integration
🔑 See [here](https://github.com/itiligent/Guacamole-Install/blob/main/ACTIVE-DIRECTORY-HOW-TO.md).
---
## SS0 Extensions (Radius, Base, CAS, OpenID, SAML, Dist)
🔑 See [here](https://github.com/itiligent/Guacamole-Installer/blob/main/SSO-EXTENSIONS-HOW-TO.md)
---
## Upgrading Guacamole
🌐 To upgrade Guacamole, edit `upgrade-guacamole.sh` to reflect the latest versions of Guacamole & MySQL connector/J before running. This script will automatically update TOTP, DUO, LDAP, Quick Connect, and History Recorded Storage extensions if present.
---
## High Availability Deployment
- 👔 **For a separate DATABASE layer:** Use the `install-mysql-backend-only.sh` [here](https://github.com/itiligent/Guacamole-Install/tree/main/guac-enterprise-build) to install a standalone instance of the Guacamole MySQL database.
- 👔 **For a separate APPLICATION layer:** Run `1-setup.sh` and point new installations to your separate database instance. Just say **no** to the "Install MySQL locally" option and any other local reverse proxy install options.
- 👔 **For a separate FRONT END layer:** Use the included Nginx installer scripts to build out a separate Nginx front end layer, and then apply your preferred TLS load balancing technique. Alternatively, AWS/Azure/GCP load balancers or [HA Proxy](https://www.haproxy.org/) may provide superior session persistence & affinity compared to [Open Source Nginx](https://www.nginx.com/products/nginx/compare-models/).

================================================
### How to build all Guacamole client extensions:
Licensing prevents some extensions being supplied in binary form, therefore these must be built from source. To achieve this, follow the exact order below on a fresh Linux system **WITHOUT JVM INSTALLED**.
#### 1. Obtain the specific JDK dependency
Download jdk-8u411-linux-x64.tar.gz from [Oracle](https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html) (needs an Oracle sign in, select the Linux x64 compressed archive and copy it to your Linux home dir) A backup of this file is achived [here]( https://1drv.ms/u/s!Asccp3ag4RnQj-dAGYyfqwf-Rf5mTg?e=uRy1DM).
### 2. Install the JDK
```
sudo mkdir -p /usr/lib/jvm
sudo tar zxvf jdk-8u411-linux-x64.tar.gz -C /usr/lib/jvm
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_411/bin/java" 1
sudo update-alternatives --set java /usr/lib/jvm/jdk1.8.0_411/bin/java
```
### 3. Clone Guacamole client source
```sudo apt update && sudo apt -y install git
git clone https://github.com/apache/guacamole-client.git
cd guacamole-client
git checkout 1.5.5 # or whatever version
```
### 4. Install Maven and build all the client binaries (with Radius support)
```
sudo apt -y install maven
mvn clean package -Plgpl-extensions
```
Build output should show:
```

### 5 Move your new extension to the Guacamole server
1. As sudo, copy the new `extension.jar` file (found in `guacamole-client/extensions/guacamole-auth-radius/target/`) to `/etc/guacamole/extensions` on your Guacamole server.
2. Adjust permissions on the new `extension.jar` file with `sudo chmod 664 /etc/guacamole/extensions/extension.jar`
3. Restart and continue configuring the new extension as per the Guacmole official documentation [here](https://guacamole.apache.org/doc/gug/).

## Custom branding & theme instructions ##
1. Install the Java JDK: `sudo apt update && sudo apt -y install default-jdk`
3. Modify `custom-theme.css` ,`guac-manifest.json`, `en.json` & `META-INF` as desired & add your logos to the images directory. (Logos must be .png files.)
4. To commit your changes, run the below commands from within the custom-theme-builder directory, then refresh your browser to re-login to Guacamole:
```
# Run within the custom-theme-builder directory
jar cfmv branding.jar META-INF/MANIFEST.MF guac-manifest.json css images translations META-INF
sudo mv branding.jar /etc/guacamole/extensions
sudo chmod 664 /etc/guacamole/extensions/branding.jar
TOMCAT=$(ls /etc/ | grep tomcat)
sudo systemctl restart guacd && sudo systemctl restart ${TOMCAT}
```
## Theme customisation hints: ##
- Do not change any of the theme's directory structure or file names. File contents can be carefully edited according to the following constraints:
- `META-INF/MANIFEST.MF`: All values in here can be updated, **BUT** be aware that `Name: branding` is linked to the commands above e.g. `Name: branding` expects `branding.jar` as the .jar filename
- `guac-manifest.json`: The "name:" value in here can be changed to anything **BUT** the `"namespace" : "custom-namespace"` value MUST match the namespace image path line found in `custom-theme.css`, eg:
```
.login-ui .login-dialog .logo {
background-image: url('app/ext/custom-namespace/images/logo.png');
width: 7em;
height: 7em;
-webkit-background-size: 7em auto;
}
```
- It is preferable to give css a range of logo sizes as shown in the template. The "smallIcon" value in `guac-manifest.json` is used for browser tab favicons. As such this file can be kept to < 80x80 pixels. The example used is 64x64 pixels.
- Within `custom-theme.css`, you may need to experiment with the the height and width values under `.login-ui .login-dialog .logo` to scale your particular logo neatly within the dialog box. Another option is to make the login dialog box larger. Under `.login-ui .login-dialog`, experiment with adding a `max-width: 4in;` or similar. There's a ton of css options available and this template is just starting point, Google is your friend!
- An easy way to debug and preview potential style changes is to tweak various values by setting your browser to developer mode.
- Your changes may occasionally appear not to update, if so clear your browser cache before doing any further debugging.
