lil snitch is one of the best tools out there, and it's what inspired me to never use apple software again... so I did the right thing and gave my lil snitch registration code to a friend. I'm still looking for a linux alternative to lil snitch that is just as robust and intuitive - but I'm stuck using a few different things to achieve the same effect. Anyone have a recommendation with a slick GUI (for some reason I really like a GUI for firewall management)
