Hello, I've searched in this forum and on Google, but no luck (or I'm too dim to recognize a hit)..

What I'm looking for is a method to measure network bandwidth used per user, per program..

Perhaps an output like:

User1: MozillaFirebird --- 5531 kB down 1202 kB up
User1: Konqueror --- 1033 kB down 201 kB up
User2: Opera --- 12773 kB 24 kB up
User2: Wget --- 52355 kB down 11kB up
User2: Gnutella --- 300112 kB down 151141 kb up
User3: IPP(cups) --- 0 kb down 1 kB up

etc.

I haven't seen anything that tracks how much each individual program is using (I've seen metering things by user before..)

Is this done somewhere?

Is it doable without a PhD in Linux?

What's the best reading material for me to figure out how to tell which program is using which bandwidth?

Thanks a ton!

The Linux Advanced Routing & Traffic Control how-to is probably what you're looking for. http://lartc.org/

I must make sure you note that as the title indicates it's ADVANCED routing and traffic control.

You should have a good idea of networking concepts to start and then once you start reading the doc, I recommend you re-read it again because you'll have missed stuff... =)

Their wshaper (wondershaper) traffic script is great! And of course, you can tune it to your hearts content, but then again that's not what you're looking for... still the rest will help guide you.

Thanks Patrick. The document is certainly chock full of information, and I'm reading through it.. Too bad it seems I have to be able to delve the full depths of queues, shaping, and policing just to figure out how to find this stuff out.. ah well. If I have the energy to actually get through it all before giving up, I'll post my results here.

Thanks again, and I'm still eager to hear anyone else's input..
