You will need to add your user to the "wireshark" group:
sudo usermod -a -G wireshark username
Then logout and log back in. Run wireshark. There should be a list
of interfaces. Double click on your ethernet one.
Done.
I double clicked "eno1".
Yow! There's an incredible amount of activity! What is all that?
Everything! :-)
If you hit the stop button, you can check out various packets to see
what's happening. But yes, particularly since you're directly connected
to the internet, there's going to be a lot of random stuff besides what
your computer is doing. In general, port 80 or 443 is http(s) traffic,
22 is ssh, 25 is email, 53 is DNS. Beyond that, you'll have to do some
research.
