Network Monitoring Tool

[Jon55]

We have several computers connected to a firewall (which is also acting as a DHCP server) and someone is using a lot of bandwidth. While I could certainly do some QoS, I'd like to track down the computer (and thus the user) that is using the most bandwidth. Is there a good networking program/tool for this?

SNMP is your best bet for doing this reliability and inconspicuously.

I use scrutinizer along with ddwrt and I can figure out who's doing what pretty easily on my network.

Netflow if supported will work as well.
