    @nixCraft OpenSnitch is open front to back.
    Maybe not as nice but is doing the job for years.

      @regendans @squalouJenkins @nixCraft I have also been a happy OpenSnitch user, see no reason to recommend something with proprietary crap when there are good alternatives, if it is not full free software that is a huge disadvantage compared with OpenSnitch

        I bought a license for a MacBook many years ago, but I no longer use it. Now I only use Ubuntu. I wonder if the license is compatible with Little Snitch for Linux.

        @x or you can use little snitch to forbid access to its own license-check server. Used to work on macos 🙂

          @nixCraft Instead of adding a small comment that most people probably won't see, the original post should include a big warning that this app is not open-source and so there is no way of knowing what it will do on your system.

                      I miss that see-which-app-opens-which-connection-when and filter it on Linux.
                      (I remember having a program on Windows 2000 which did exactly that: a personal firewall with a GUI).

                        @nixCraft And OpenSnitch makes things actually have to get permission to do it. (You can set it to always allow/reject/drop or to do so for an interval.)

                        I've found a surprising number of things making connections they really shouldn't be. One that scares me is many thumbnail engines will open URLs inside things... (They're not browsers. They're not up on the latest security issues/etc, they don't have ad blockers or privacy guards, etc etc. They should not be allowed to go online ever!)

                        Kind of bugs me how many things just don't even try to hide telemetries that the user doesn't get to opt out of. Many game engines are bad about this for example. They just phone home and there is no setting in the game to turn it off.

                              @randomdaz @p3ter @nixCraft is that the thing that you could install stuff and do whatever you wanted and upon restart it was back to pristine install? I remember folks losing their minds when AOL instant messenger disappeared on high school computer lab PC restarts. Also, remember computer labs? Ha!

                                Actually it looks like my memory is failing. It was an inbound firewall that allowed you to easily block based on events
