I have been using Wireshark for some time on my Vista laptop but I couldn’t get it to work on my smaller Ubuntu laptop. When an update was installed today for Wireshark on my Windows machine I decided that now was the time to fix the problem on my old Ubuntu laptop.
It was a simple fix that was documented in the wiki. All I had to do was run this command to have WireShark detect the interfaces.
sudo setcap ‘CAP_NET_RAW+eip CAP_NET_ADMIN+eip’ /usr/bin/dumpcap
