RE: Network Traffic Monitor

Looking at all the replies to date, I feel the stress of all the replies
was more on *packet capturing* which is a bit different than *traffic
monitoring*, which Jason is looking for. I had faced the similar type of
issues in the past where ethernet of some machines looked extremely busy
and generating a lot of traffic even when all the usual services and
applications were stopped. 

For monitoring purposes I prefer sysinternals' utilities available at
http://www.sysinternals.com/ntw2k/utilities.shtml on windows platform
which can provide you the details of your machine utilization in many
different ways. For tracking the inbound and outbound traffic with
source destination address and ports info, I recommend installing some
host based firewall on Windows machines, like Tiny Personal Firewall.
Its status window provides all the information which you need to know
about the network traffic of your machine.

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.
