Solving the No interfaces problem with Wireshark in Ubuntu 10.10

Run the following in the Terminal:

sudo addgroup -quiet -system wireshark
sudo chown root:wireshark /usr/bin/dumpcap
sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap

Then run the following changing YOUR_USER_NAME onto your user name:

sudo usermod -a -G wireshark YOUR_USER_NAME

That's it. No need to restart or even log off. Just start Wireshark and select the network interface.

I just went to Capture -> Interfacess... and clicked the Start button for eth0:
