"OpenSnitch also has a nice graphical user interface that lets you see at a glance:
What applications are accessing the web
What IP address they are using
What User owns it
What port is being used"
I used Wireshark twice but it was too much over my head. Like completely over. I've used every netstat
-like CLI program and too many columns for me foe the basic info. This program (opensnitch) looks like takes a layman approach because I am a layman.
Opensnitch is a firewall. I LOVE ufw but its GUI does nothing for me. Have tried/installed this from source? What's it like?
