I know there are some tools including firejail and bindtointerface on standard Linux Distros, but they don’t run in userland, so whenever the deck updates they will be overwritten.
Anyone have any ideas how to block access on a Steam Deck?
Have you tried OpenSnitch
Thanks for the suggestion, I think the main issue is doing it on the Steam Deck. On a native Linux machine it’s easier. I don’t see a way to install OpenSnitch on the Steam Deck with the read-only file system and whatnot. I think a pi-hole and block DNS might be easier than trying to mess with SteamOS.
Uh, under Windows use NetLimiter. Under Linux? Try AppArmor based policies, otherwise… No idea.
Hmm, I wonder if SteamOS has AppArmor by default so I can tinker with it.
IIRC it is based on Ubuntu, so yes.
