Monitoring Internet usage / bandwidth
Posted on 2006-07-07
I'm a network admin for a small company running 30 Win XP clients and
a few Windows 2003 server machines.
Our last few internet bills have been pretty hefty (the most recent was 10GB over our cap!!).
I'm suspecting that one or two users are abusing their internet priveleges a little.
What I'd like to do is monitor internet usage (e.g. X MB downloaded this month) on a
per user and possibly per machine basis- and impose restrictions / quotas
at the system level (if the friendly emails suggesting they cut back on downloads don't work).
It would be good to monitor usage regardless of protocol e.g. FTP, HTTP, P2P file sharing etc.
A solution that integrates fairly easily with our A.D. user accounts would be great. Has anyone experienced
the same sort of problem or aware of a suitable solution?
We're currently running a Linux distro called IPCOP for our gateway / proxy / firewall.
I would open to suggestions to either replace this or augment it with proprietary software.
