If you must have a console app, you might want to try ngrep, but I'm not
terribly familiar with it.
I really recommend bringing your box up to 5-Stable, cvsup your ports
tree, and install ntop-3.1_1.
It has its own web server - doesn't depend on Apache - and you'll find
lots of information there, including graphs for total bandwidth used
over the last hour with 5 minute resolution, top 3 talkers for the same
period, same for last 24 hours with 1/2 hour resolution, and lots more.
Well worth the investment of time.
