Perhaps Wireshark?  Per that program's Web site, "Wireshark is the world's
foremost network protocol analyzer, and is the de facto (and often de jure)
standard across many industries and educational institutions."

See http://www.wireshark.org/about.html

I run Wireshark under Ubuntu Feisty.  One can configure bespoke Wireshark
capture sessions to capture and filter network traffic from one or more
network interfaces.  Filtering, especially, enables you to focus on specific
types of traffic...

Cheers & hope this helps,
