Hi,
found Douane, a personal firewall:
http://douaneapp.com/
and thought it might be a good addition to alphaOS.
The code (GTK3):
https://github.com/Douane/Douane/wiki/Compilation
The Wiki:
https://github.com/Douane/Douane/wiki/Dependencies
The arch Linux package:
https://github.com/Douane/Douane/wiki/Archlinux-Packaging
The difference to other Linux firewalls is that it has the possibility to protect the user's privacy by allowing the user to control which applications can connect to the internet.
What do you guys/gals think?
