I'm happy to (finally) present a new tool: 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. News: I'm working an a complete rewrite of jNetMap for the 0.5 release. This project has grown to much and the current framework is not able to carry more features. Please be patient, it may take a while :-)
I was also able to take over the project space over at sourceforge.More...

I'm running the software on a Win XP Pro machine and am also getting nothing. I'm a networking noob so I may totally be screwed up, but I think I'm using it correctly.

Ok, as a do not use Windows, I haven't tested it on non-unix systems.
This looks like a serious problem however, so I'll investigate it on my VM.
Meanwhile, just add the devices manually using "Edit > Add" or with the right-click menu.
Edit:
Confirmed.
Anything below 1000ms will fail. I have no idea what the problem is...
(Linux: 50ms, Windows 1000ms)

I can confirm that on Vista 64, it does not seem to find anything at all no matter the timeout. I tried everything up to a few thousand ms and still got nothing.
However, if you add the nodes manually you can "check" them and they will be green. I assume these use the same methods so something is wrong in the scan somewhere.
Could it be scanning on the wrong network interface (Vista creates a *lot* of interfaces for tunnel adapters and the like - I also have a VMware virtual interface that could be throwing it off)

Erudite Sir, This is really very effective software. I appreciate the efforts of administrator and very grateful to him for posting such great information. You have disseminated it in an excellent way. You should not rest on your laurels and continue working even harder!

Great utility, thank you very much for sharing.
I have a device on my network that responds to ping via a console command line but will not show up as connected (green)on the map. What could be the cause of this?
#14Submitted by rakudave on 17. August 2009 - 2:10.
I know, a friend of mine has this same issue, but I have no idea what the problem is. jNetMap sends a standard ICMP/ECHO request, just as "ping" does... any luck using ports?

I found your post very informative and helping in which printer is still on is very good and interesting method. Especially your way of describing is very excellent and easy to use. The tutorial video makes your post so interesting and helpful. After exams I will try your method. Thanks for sharing very effortless and great post.

I still cannot ping my virtual server from jnetMap.
The virtual server can ping from term but jNetMap can not recognize them.
Also pfsense router that provide my internet, still not connected from jNetMap.

Ok, the triggers are just interfaces to some scripts you'll have to write. (batch-file on windows, sh or similar on UNIX). I plan to intrgrate SMTP (Email) and Twitter into jNetMap v0.5, but that's still some time away, so please be patient...
As for jNetMap not recognizing some hosts, I'm aware of that, but I have no clue why this happens. You might have to use port-mode to overcome this...
I scanned on a Vista laptop and although it goes through all the ip addresses, nothing comes up on the map. Java is 6.0.130.3
same here... scanned and no devices appear. vista 64bit
try setting a higher timeout value (Edit > Scan > Timeout)
50ms works fine for me (ubuntu linux), but setting it to 500ms might help
I'm running the software on a Win XP Pro machine and am also getting nothing. I'm a networking noob so I may totally be screwed up, but I think I'm using it correctly.
KP
set it to 500ms, still nothing
how do you get this to run in Windows XP?

Wonderful app. Works good on xp with 1250 timeout.
I think it would be cool if you could add a background image like a floor plan. Maybe that's a feature you could add in the next release.
implemented in version 0.3.1
(thanks for the idea :-)
