Nosocks

Control access to the internet for non-static apps on Linux.

what is nosocks?

Nosocks uses library preloading to limit access to the internet for apps that are dynamically linked to libc - or do not have libc statically linked.

---

usage

1. Download zip file from github to Archlinux.
2. Unzip, cd to zipped directory, in the terminal run makepkg, and then pacman -U nosocks-*
3. As root user edit app names in the /etc/nosocks/nosocks.conf. Use - instead of a space for app names with spaces. For example "python3 script.py" should be "python3-script.py".
4. Close and restart apps to check internet access. nosocks does not apply to the root user
5. For wine apps you need to add /usr/bin/wineserver, and the exe name separately
