RE: Network Traffic Monitor

There are many packet capture packages, like snort on Linux. On Windows,
there are some freeware options, like Ethereal or AnalogX Packet Monitor. Of
course, you would have to place the Linux or Windows box somwehere to the
outside of the switches, with two NICs installed. You would get different IP
address info depending on whether you put it inside or outside of the
router, as the router is doing address translation.

Alternatively, your may be able to monitor traffic on your firewall or
router. E.g., a Windows freeware app called WallWatcher can monitor traffic
on a Linksys router. Some are monitorable via SNMP.

Is that too basic? That just about exhausts my knowledge in this area.

I'm curious if anyone knows of any software Windows or Linux that can
monitor all traffic going out of the network, particularly any unusual
traffic. I had a computer infected with a mass mailing program that sent out
enough traffic to lock up my firewall the other day, which is also the
firewall for all our web/mail/app servers. Any ideas would be greatly
appreciated. Thanks in advance.
