This tool gives a small GUI showing the last pinged time and latency to various hosts.
Hosts are specified in files where the last word of the line is the host or IP, and the rest of the line is the name. Lines starting with # are comments, and each file gets its own tab in the window. Files are specified in a list at the top of the script.
The original system this was meant to run on had a quite old Python installation, so this replicates some functionality of later Python versions. In theory, this should work on any Python newer than 2.4, provided that the Tk library is compiled against Tk 8.4 or newer. Python 3 isn’t currently supported, but modification for this should be trivial to do.
