jNetMap For Linux

jNetMap is an utility that will ping all registered devices every x minutes, updating it's status according to the result of the ping. Alternatively you can also monitor a specific port, such as port 80 for webservers. Available devices are green, unavailable devices are red. Gray means "unknown" and orange "not found".

To start drawing a new map, select "add", enter the details and hit enter. You can connect the devices by right-clicking on a device and selecting "connect". The rest is pretty self-explanatory I guess...

You can also save and open existing maps so you don't have to redraw everything.

It also supports arguments, e.g. "java -jar jNetMap.jar some/where/some.netmap" will open the "some.netmap" when starting the application. This also works for the "open with..." option in any OS.
