Monitoring amount of data through network interfaces

[astaude%silas.cc.monash.edu.au@localhost (AS)]

Quick question:

Just wondering if it is possible to see the number of bytes passed through
a network interface - all would be nice but specifically dial-up interfaces
would suffice - particularly modems.
Win95 seems to do a nice job of this showing sent/received bytes - I guess
I had something like this is mind so that I could compare my figures with
what my ISP says.

Thanks!

BTW, thanks for all the replies re: NetBSD and ZIP compatiability.
Adding my ZIP was one of the easiest pieces of hardware I have ever added
to NetBSD!
