Nothing Earth-shattering here, but this one always trips me up and I spend 10-15 minutes trying to remember how to set it up so that I can wireshark as a non-root user.  Works like a charm under Ubuntu, Xubuntu, and Debian 6.x.  Prolly works under all Deb derivatives, but I won’t stake my career on that 🙂

Anyhoo, here is the code:

sudo setcap cap_net_raw=+ep /usr/bin/dumpcap

Sweet! Props to the folks on the Ubuntu forums: http://ubuntuforums.org/showthread.php?t=1086288
