How to run Wireshark from Ubuntu Command Line
I have installed wireshark to my Ubuntu server but when running from the command line using this simple example:
wireshark -k -a duration:120 -w wireshark_results
I get a display error:
** (wireshark:32689): WARNING **: Could not open X display (wireshark:32689): Gtk-WARNING **: cannot open display: :0.0
This was after running:
DISPLAY=:0.0; export DISPLAY
What do I need to do to setup Wireshark on Ubuntu on DigitalOcean to capture packet data to file?
