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.

Elevate privileges between Python program ( and Inter-process_communication ) (programming.dev)

Hi everyone,

I have a Python program (A) that run under a regular user account. (good)

When some events occur in (A) I need to modify my nftables and only the root is allowed to do so.

I've come up with 3 ways to do that (if you know other please share) but I don't which would be the best.

Make a sudo call from (A) with from subprocess import run but I will need to store the password ! and I don't think is possible to keep it encrypted and decrypted when need it (it's a flaw)
.
Make (A) writing a file with the requests. Create a (B) daemon (that run as root) that check that file every X and do the necessary
.
Make (A) do an IPC ( Linux socket ) to (B) daemon (that run as root) and does the necessary.

I suppose that the solution 2 is less heavy that the 3 ? But if I'm not mistaken it will react also slower ?

Thanks.

It's a good way of solving it. It's not scriptable though as it requires user-input.

indeed I need it to be scriptable.

Then implement polkit perhaps? https://polkit.pages.freedesktop.org/polkit/polkit-apps.html

Basically the root using bit is handled via polkit. Three unprivileged bit calls the privileged bit via polkit.
