" Wireshark is an open source network packet analyzer. Without any special hardware or reconfiguration, it can capture live data going in and out over any of your box's network interfaces: Ethernet, WiFi, PPP, loopback, even USB. Typically it's used as a forensics tool for troubleshooting network problems like congestion, high latency, or protocol errors — but you don't want to wait until your network is in trouble to learn how to use it. This weekend, why not take a look at your network traffic, and learn how to use Wireshark to your advantage?

"Wireshark is a GTK+ application, although the project also includes a console-based front end named TShark that features most of the functionality found in the GUI version. Considering its reputation as a useful administration tool, you will probably find it in your distribution's package repositories. If not, you can download packages for several distributions on wireshark.org, along with the source. The current release is 1.4.1. Mac OS X and Windows binaries are available as well, which you may need to analyze machines running those operating systems (more on that later)."
