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.
Doesn't flatpak use bubblewrap for it's permissions? Otherwise would those programs work in distrobox?
I read an earlier Lemmy post where someone suggested setting the WINE proxy settings to some invalid setting for the game as a work around. I need to test it and see if it works.
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.
You can't install applications on steam deck and there is a read only file system???? Whaaaatttt???????
Edit: I asked a friend that has a steam deck, he explained you can easily disable the read-only system, do whatever you want on a Linux system and reenable it afterwards.
From what i understand any changes to the system outside of the userland will be overwritten after a SteamOS update.
That is correct. The best case is to write a script to make your desired changes, and then run it after each system update.
My own use-case is that I have a NFS mount-point for my Steam Deck to use extra storage on my NAS. After the first time I figured out how to get it mounted, I made a script to disable read-only filesystem, make all the changes to the system, and then re-enable read-only filesystem. After every system update, I just run that script once.
Thanks for the reply!
I can find my way around bash, but the most advanced script I've personally authored it probably "Hello World." Would you be willing to share the script from pastebin or github? IDK, I guess you could copy and paste it posted on Lemmy.
I think I need to do exactly what you recommended, but I may need some help setting it up. So are an update, you simply run the script to get the system changes re-applied?
This is the script. /home/deck/scripts/fstab contains my customised fstab file.
Yes, after an update, I just run this script once.
#!/bin/bash
if [ ! -f ~/.config/kdesurc ];then
touch ~/.config/kdesurc
echo "[super-user-command]" > ~/.config/kdesurc
echo "super-user-command=sudo" >> ~/.config/kdesurc
fi
if [ ! -f /var/mnt/nas ];then
sudo -c 'sudo mkdir "/var/mnt/nas"'
fi
sudo cp -a /home/deck/scripts/fstab /etc/fstab
sudo steamos-readonly disable
sudo pacman -Syy
sudo pacman-key --init
sudo pacman-key --populate
sudo pacman -S --overwrite "*" nfs-utils
sudo steamos-readonly enable
sudo mount -a
Thank you. I really appreciate you sharing, this helps a lot!
No you can install them persistent and update your OS
