This tool pings all the servers named on the command line, and shows you a dashboard display of which hosts are up, which are down, and how long that has been the case for. It uses raw sockets with protocol icmp, which normally requires elevated permissions. Hence you'll typically invoke it with something like sudo
pingboard attempts uses socket.getaddinfo() to resolve your servers to IPv4 or IPv6 addresses. It only takes the first returned result. Hence you can specify an IP address (as socket.getaddrinfo() will 'resolve' that to the relevant IP address). But also, if your name resolves into multiple IP addresses then it may not be obvious to you which server is actually being pinged.
Instead of listing servers on the command line, you can pass a --server-list file that lists the servers. If you do this, the file format is one server per line. Any text on a line after a white space is treated as a comment for that server, and is also displayed by pingboard.
Use the --log-file option to have pingboard write a log file of events, so you can have a historical record of when servers came up and down.
For other options, run pingboard with the -h option.
In order to install locally, clone it, then from within your checkout run:
pip install .
Or, to install just for yourself:
pip install --user .
In the later case, you might need to take extra steps to have the pingboard available to you (i.e. add "$HOME/.local/bin" to your PATH)
If you want to have a copy you can hack on, install the package with a symlink, so that changes to the source files will be immediately available to other users of the package on our system:
pip install --user -e .
