I found XMonitor and am using it now. It is a very primitive app, but it seems to show some sort of a network activity counter.

It counts MB in and out. The interface is seriously flawed, though.

I'm no hardliner on interface, but the XMonitor interface is below par.

It's shocking to see how much data I download each day!

Anyway, it'll do untill I find something more specific.

There should be a program that counts each bit in and out of every port of the machine and stores the data numerically for inspection. Also to be able to measure amount of data from date X to date Y. Like how much from 9/1 to 10/1 2002.

It's a simple thing but I don't see XMonitor do it.

It only keeps record of the data I/O since the machine was started. Ah, well....
