Yaunc is Yet Another Uptimes.Net Client. Its pretty good I think. I like it. For more info about the project, visit www.uptimes.net.
I wrote Yaunc as an exercise to learn C and the unix API. You can download the latest version here. Older releases are available via ftp.
Platforms: Linux, Free/Net/OpenBSD, Solaris. See the documentation included for more details.
Yaunc has been updated to support version 4.2 of the uptimes.net protocol.
Feel free to contact me with suggestions, bug reports, or other feedback.
