I remember before Little Snitch there was ZoneAlarm for Windows[0] (here is a good screenshot[1]). No clue if the current version of ZoneAlarm does anything like that (have not used it in 2 decades). I always found it weird that Linux never really had anything like it. [0]: https://en.wikipedia.org/wiki/ZoneAlarm [1]: https://d2nwkt1g6n1fev.cloudfront.net/helpmax/wp-content/upl...

It's interesting hw lng it took for linux to get a user friendly application firewall like OpenSnitch

I just tried littlesnitch and it did not resolve very many ips to domains, which is pretty basic. It also failed to identify most processes, and they were grouped under "Not Identified".

I know it sounds crazy at this point, but with popular YouTubers switching to Linux, gamers overall well-aware of Steam on Linux advantages and switching as well, plus popular software like LittleSnitch getting ported, 2026 can without irony be named as Year of Linux Desktop, right?

I think there is a lot of talk (and this is good), but very little action. Market share is still incredibly low for LNX. I believe only a small subset of people actually attempt the jump from WIN to LNX (since most just want to play their games and run their programs without hassle) and then quickly realize that its tougher than they anticipated and swiftly return to WIN.

This is what I used! At some point I managed to block DHCP lease renewals on my computer, and Internet would always stop working after a given timespan. Took a good while to figure out I caused the problem myself.

and that's how you learn... Shooting yourself in the foot really helps to built intuition!
