It’s been a while since I looked into details of wayland, but one thing I recall is that a lot of things depend on the specific compositor / desktop environment you are using.

X is very open: you can easily query open windows etc, while on wayland things are less standardized / more hidden.

Which compositor do you use?

systemctl mark-all-as-read

Thank you! Exactly what I’m looking for.

Thanks 🙏 Opensnitch is exactly what I’m looking for

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.

FreeBSD is actually a “real unix”, in the sense that it is derived from the original source. Wikipedia has this nice ancestry tree: https://upload.wikimedia.org/wikipedia/commons/7/77/Unix_history-simple.svg

Should this go to Bun Alerts?
