WMServices
WMServices is
a dockable app which intends to make checking for server availability a
bit easier. The app, given up to five server IP's or hostnames and
ports continuesly
checks whether they are up and informs the user accordingly(using green
or red font).A log can be created if the user needs one! The
application is currently on version 0.4 which seems
to be working just fine, although a few additions need to be made. No
strange libs are needed to built it, just X windows and the standard
libs provided by any distribution.
See a screenshot of the app:

04/7/05 -> NEW VERSION 0.4.2 : Fixes bugs concerning command
line parameters.
