Looking for a packet sniffer? Need to check out your network. Wondering, what is happening on your local VPN? Check out Wireshark. (Previously named Ethereal.)
Just put you network card into promiscuous mode.
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.
= Besides, free, Open Source, Windows, Linux, and Mac OS X.
