Is there a relatively simple way to block network access to a program? Avoiding the command line ideally.
Heroic Launcher has a “run game offline” toggle for games that are installed/added through it, but I am trying to cut out the middle man and install non-steam games directly through Steam.
Steam launch commands? Any built in firewall?
Thanks in advance!
Haven’t tried it on Deck, but iptables can do a per-uid based rule which I’ve used in the past
I.E. login+run restricted games under a particular login, OR sudo to that user for running but allow X-forwarding+PulseAudio to my current login
OpenSnitch is a solid option, but I don’t find it that reliable to install on Arch. Instead I’d suggest looking at Safing’s Portmaster.
I don’t know if it works as I think it does, but you can try relaunching steam in offline mode
