I've found that iftop and ntop are both pretty useful tools. Relatively 
simple to figure out too - you can apt-get them both.

ntop provides you with a web based interface to tell you all kinds of 
stuff about where traffic is going.
iftop shows you a real-time usage of your interfaces (rather like top does).
