Wireshark Fix for Error No Protocol Specified

Working through a pen testing lab, was getting access denied when trying to capture.

Tried running sudo and it doesn't let you cause it's a security risk.

But when we're in a pen test lab, i'm ok with that risk.

But I was still getting this error "no protocol specified"

> sudo wireshark
No protocol specified

(wireshark:3962): Gtk-WARNING **: cannot open display: :0.0

The fix I found

> export XAUTHORITY=/home/mooreted/.Xauthority 

> sudo wireshark
