Net usage

[Geoff Shang]

Hi:

I was looking at the various plans offered by our major phone company for
their cable service, and I began to wonder just how much data do I send and
receive via PPP per month?  Would a volume-based account be OK if I didn't
exceed 500 MB?  I guess I want to know if its possible to log data
transfered by an interface over a month or several in order to determin how
much I use.

Geoff.
