Re: Need Help Configuring Wireshark
I've recently installed Ubuntu 12.04 and Wireshark. Due to issues with a video driver I had to install Ubuntu again. Both times I used the following procedure to fix the permissions issues with Wireshark:

After following the procedure and logging out/in Wireshark runs without error and I can capture on my Ethernet and WiFi interfaces.
Good luck!

Re: Need Help Configuring Wireshark
Hey colo, I actually got it working after trying out the instructions that CyberpathicGhost posted.
BTW- thanks to CyberpathicGhost for that! I basically ran the commands like it was the first time and that did it. No error messages and I didn't even have to do a fresh install :guitar:
Re: Need Help Configuring Wireshark
I faced the same problems (on Xubuntu 11.10) as the OP. The original blog those instructions are from (https://blog.wireshark.org/2010/02/r...eshark-as-you/) has two unfortunate errors in the section of how to set up dumpcap using Linux capabilities, rather than making dumpcap as setuid.
Error 1: forgot to chgrp of /usr/bin/dumpcap to the wireshark group
Error 2: didn't add 'eip' to both capability settings.
Here's how the instructions should read:
$ sudo su - root
# sudo apt-get install libcap2-bin
# groupadd wireshark
# usermod -a -G wireshark gerald
# chmod 750 /usr/bin/dumpcap
# chgrp wireshark /usr/bin/dumpcap
# setcap 'CAP_NET_RAW+eip CAP_NET_ADMIN+eip' /usr/bin/dumpcap
Note: on modern Ubuntu's you probably don't need to install libcap2-bin. I already had it.
