Network Monitoring on Linux
 

Is there a program on Linux that allows network monitoring? We have a client that transfer large files within the LAN, and I wanted something that would monitor traffic so I can see if bandwidth is low.

If you have GUI use System Moniter---->Resource. This may help.. But I think you have a server, you may not have installed GUI.

Cheers!!

Well, you could try wireshark (aka ethereal) but its probably not the best tool for the job, without a bit of work (I just don't know a better one...).

It will capture every packet on an interface and you'll have to do something to be able to see the wood for the trees (ie, get over information overload). I think what you want would be do-able, but I'm doubtful that it is the most convenient way...but I'd still try it, given I'm a man with a hammer and its the one tool that I know. YMMV.

Can webmin help you ?

ntop

or anything that can gather netflow data from your switches and routers


You could also look at mrtg or rrdtool
