determining what process is hogging bandwidth

I have a cluster of 4 machines running OpenSuSE 10.3. It appears that
one of them is really hogging bandwidth right now. Unfortunately I
can't just reboot these machines right now as there are multiple users
on them for a few more hours. Is there any utility or particular
method to find out on a process basis what is using up the most
bandwidth?

TIA

Have you tried htop?

I'll check it out. Thanks for the suggestion. The only software I
was familiar with before was a top-esque monitor that my friend wrote
quite a few years back. Unfortunately he never released it and ended
up losing his source tree of it.

Well I just snagged it and took a peek at it. I can tell I've found a
definite replacement for 'top', but I didn't at first glance notice
anything about monitoring the network bandwidth that each process is
utilizing. Of course I only got to look at it for a few minutes
before my ride got here, so I guess I'll have to look some more
tomorrow.

Ah, _network_ bandwidth ... you just stated "bandwidth" in your OP.

ntop is what you want. Run it on the network router to see the bandwidth
component and endpoints of each connection to the Internet.

Yeah that's why I specified; I figured that someone had taken it to be
memory or processor bandwidth. My bad.

ntop is looking absolutely perfect for what I was trying to do; as
soon as I can find out if our WAN will handle the rflow traffic
without any serious hits I'm going to try to put it on all of our
routers.

Thanks!
