Re: Network Traffic Monitor

I think that better solution is sniffing all packets which remote point are
port 109, 110 and 25 (pop2, pop3 and smtp ports). One of your host have a
lot of conections, this is the host infected, but if you try this method,
the sniffer needs to be instaled between firewall and switches:

T1's > Router > Firewall > Switches > All servers and PC's
                                      ^ Sniffer.

Subject: Network Traffic Monitor


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.
