The "etherman" tool suite out of Curtin University in Austalia is a free
start.

I just recently snagged MRTG, a freeware SMNP package that will poll a router
allowing snmp access. It seems like a simple traffic monitoring/averaging/history
program that is too simple to use, but provides easy to understand information
in a visual context. Cisco's are really easy to configure for snmp polling
by MRTG.

I'm sorry I can't post the ftp sites. Can't think of them off the top
of my head and too late to search. Apologies. Maybe someone else knows
firsthand?
