It really messes up the inbox for people that prefer threaded views. As for software recommendations, have you looked at tcpdump? Its a lot of manual labour, but with some simple scripting you should be able to easily figure out what kind of traffic is eating your pipe. If you dont mind a buggy, resource eating hog with lots of security issues you could look at ntop. It has a webinterface that draws very pretty graphs and diagrams with all the information you could possibly want. But as I said, it will eat resources and dont blame me if youre hacked while running it. Just install it, fire it up and let it run for a few hours and you will have enough data to work with I think. If you like it you can keep it running, but as I said, dont blame me. -- R
