As sad as it is, I had to bring work home the other night. I had some network packet sniffing traces to work through. There’s one tool that stands head and shoulders above the rest when it comes to this type of thing, so I installed Wireshark onto my PC. It is listed in the Ubuntu Software Centre.
I only had to analyse the traces, I didn’t need to do a new capture. I did still notice that the interface list in Wireshark was empty. This usually lists the network interfaces that Wireshark has found. You can then select the interface you want to do a traffic capture on and away you go.
As I say, I didn’t need to do a new capture so it didn’t affect me, but it left me wondering how you get the interfaces to show up in Wireshark in Ubuntu. The trick is to start Wireshark as a super-user. You can do this by opening a terminal window and typing:
You will then be prompted for your password.
Wireshark will then display all of the network interfaces it can find. Business as usual.
