Configuring Wireshark

Non-root users haven't enough rights to capture packets. To allow non-root users to do that in BackBox Linux, just open a terminal and run:

$ sudo dpkg-reconfigure wireshark-common # then enter YES

$ sudo usermod -a -G wireshark $USER

Logout from the system and then login again.

The user is now allowed to capture traffic from all the devices the BackBox machine has.
