If a specific file or uri is requested, that will be requested instead, i.e. http://github.com/cnlohr will request ```HEAD /cnlohr HTTP/1.1```.\n\nIf a regular hostname is requested instead, ICMP (regular ping) will be used.\n\nThis allows cnping to be operated in environments where ICMP is prohibited by local computer or network policies.\n\n## Installation\n\n### Ubuntu\n\n```\nsudo apt install libxinerama-dev libxext-dev libx11-dev build-essential mesa-common-dev libglvnd-dev\ngit clone https://github.com/cntools/cnping.git\ncd cnping/\ngit submodule update --init --recursive\nmake linuxinstall\n```\n\n'linuxinstall' builds the tool, copies it to your /usr/local/bin folder, and sets the cap_net_raw capability allowing it to create raw sockets without being root.\n\n```\nsudo cp cnping /usr/local/bin/\nsudo setcap cap_net_raw+ep /usr/local/bin/cnping\n```\n\nNote that if only http pinging is requested, you do not need cap_net_raw or root access.\n\n### Windows\n\nA Windows-exe can be cross compiled on Linux, just install the necessary dependencies and compile it:\n\n```\nsudo apt install binutils-mingw-w64-i686 gcc-mingw-w64-i686 g++-mingw-w64-i686\nmake cnping.exe\n```\n\n### Other distributions\n\nSee our Wiki page for information on more distributions, e.g. Arch, Void, Gentoo or Fedora: [Binary packages and distributions](https://github.com/cntools/cnping/wiki/Binary-packages-and-distributions)\n" }, { "path": "cnping.1", "content": ".TH CNPING 1 \"Dec 2020\" \"version 1.0\" \"User Manuals\"\n.SH \"NAME\"\ncnping \\- Minimal Graphical IPv4 Ping/HTTP Ping Tool\n.SH \"SYNOPSIS\"\n.B cnping cnping [host] [period] [extra size] [y-axis scaling] [window title]\n.SH \"DESCRIPTION\"\n.B cnping\nis a minimal graphical real time IPv4 ping tool written in C.\nIt can send pings via ICMP (regular ping) or HTTP which is useful \nin case ICMP is prohibited.

\n cnping is a minimal graphical real time IPv4 ping tool written in C.\nIt can send pings via ICMP (regular ping) or HTTP which is useful \nin case ICMP is prohibited. Responses are displayed as vertical bars \nin a graphical window. Red bars indicate a response was not (yet) \nreceived, white bars indicate the response was received with a height \nrelative to the round trip time. Additional statistics are displayed \nas an overlay.\n

\n

\n cnping uses rawdraw so it is OS independent and very light weight.\n
