I'm looking to solve some problems in my home network, first I will lay out the setup.

teh intarweb! -> Redhat Linux (router) -> (6) Computers with static IP

Each of the computers has a local IP of 10.0.0.*

I live with 3 roomates and we do alot of downloading and games and surfing, hell, we goto an engineering school! Anyway, it'll all be good until we start doing uploads on file sharing and the ADSL download speeds drops by like 100k. (When we upload 13k we lose a ton of speed)

We use MRTG on the Linux machine, but it doesn't help much, it doesn't tell us where the bandwidth is coming from on the network, so all we see is that theres 10k uploads total, and 100k downloads, etc.

So what I want is a way to see how much upload/download each person is doing by IP (or by name) ... but I don't want to know about inter-network traffic, like sharing files with each other and stuff...

Any idears?

I use a product called Iris...it is an enterprise-level packet sniffer.
It normally costs around $1000.00, but right now you can download a 15 day trial version from their site(http://www.eeye.com/html/Products/Iris/Download.html) That should be long enough to figure out where you traffic is coming from!

Since you're using a linux router box, try nmap, ethereal, and etherape.
