Currently I use ufw and Firestarter, and I'm just learning how to use a firewall.
When I used windows there were a couple of firewalls that could block a process which tried to establish connection and show a dialog with the process name and buttons with preferred actions.
Is there deb package which can block connection and show which process tries to establish it, giving the user a choice what to do with the connection?
I really need it because I cannot figure out which process was blocked by Firestarter given that log entry:
