Mac OS X & Wireshark - No Interfaces Found Fix

Posted by Justin Carmony on May 12th, 2011

Alright, quick fix for a problem I always forget. When running Wireshark on OS X, when I go to select an interface to capture on, I get an error telling me there are no available interfaces to capture on. This is because Wireshark is running as a user that doesn’t have ownership on these interfaces.

Solution, open up the terminal and run the command:

sudo chown <username> /dev/bpf*

After a reboot, these permissions get reset, so you need to do it after each reset (and hence why I need this every now and then but can never remember the command).
