Is there a firewall solution for Linux that will notify me of any connections that other processes try to establish, and let me allow/deny each connection manually?
I would like to get more concious about which tools are connecting to the internet, and how often.
You could drop all and use the log function to see all traffic denied
Thanks, I’m aware, but I’m looking for an interactive application that lets me create rules on the fly. I don’t want to have a one-time session where I check which tools connect to what, but rather something that interrupts me throughout the day…
If such a thing doesn’t exist, tipps on how to build it are welcome too though.
