jNetMap is written in Java, so it is platform independent.
Ensure you have Java 6 installed on you machine.
NEWS
23.12.09: I'm currently working on a bottom-up rewrite of jNetMap, as the current
framework is old and from a software design standpoint a crime.
Just be patient, it might take a while.
DOCUMENTATION
There is an extensive documentation available where all functions are explained. Or just look at the source...
What is jNetMap?
jNetMap 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.
... not what you were looking for? There was another project that was called jNetMap back in 2006, you can visit it here.
