More Networking
Here are some more networking tips and tricks that I’ve found helpful.
List out the current ports that processes are listening to
To see a list of all processes, and the network ports they are listening to, you can run this command:
sudo lsof -nP | grep LISTEN
That will output a list of running process, and the ports they are currently listening to (the far right column):
