Wireshark

Hi every one
I needed to download wireshark, so I looked for an ubuntu version and I found it.
All you have to do is to open your "Synaptic Package Manager" and type wireshark, download it.

Well, If you faced this problem when you start "capture"
There are no interfaces on which a capture can be done.

That's because only root user can access network interfaces, so you need to run wireshark as a root user
Press          ALT + F2 

Then type        gksudo wireshark 

Good luck
