I assume they're using private addresses? If so, just use static IP's on the
client machines, and keep a record of who has what IP.
Then its simply a matter of analysing the logs, since the IP address is
captured by Squid when the client makes a request.
You would have to block port 80 at the ISDN, or make it company policy that
all clients use the proxy.
However, this won't show what the clients are sending, only receiving.
Other suggestions:
- use a switch with SNMP capability, and snarf the octets using something
like MrTG.
- Use NAT with a Linux box as a gateway and get reports from the accounting
module.
On a side note, if you think that Squid & email are bandwidth hogs,
just wait till Joe User finds out about Napster... ;-)
