From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I got one!
What constrains access to an rpc socket in the file system? Is it just the permissions of the socket or is there more to the whole process?
E: I originally wrote port instead of socket because it was early lol.
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!
