Ever had a question about Linux but felt too afraid to ask? Well now’s your chance, ask any question about Linux, no matter how noob or repeated it is, and I and others will help answer them.
Previous noob question thread: https://lemmy.ml/post/14261893
What’s an rpc port anyway? Do you mean DBus? Then FS perms of the socket. Perhaps also something in the protocol itself.
I meant to write socket instead of port because I was tired.
If for example a program can take rpc over a socket which is a file somewhere is it just the filesystem permissions that determine what can be done or is there more at play?
FS permissions are the main thing, yes. One can build more systems around it (don’t mount the socket into a Flatpak container, if you don’t want the Flatpak to talk to DBus) or (implement some sort of auth protocol like TLS does).
Ty!
