KunalSin9h / _Example polkit rules_.md
Created September 10, 2023 14:26 — forked from grawity/_Example polkit rules_.md

These are only examples, for a few very common actions. You are expected to write your own rules for the rest. The syntax is regular JavaScript, but see the polkit(8) manpage for the object structure and available API. These examples are for polkit versions 106 and later, with the JS interpreter. They won't work with Debian's polkit v105.

  • If you don't know the action name, run pkaction:

    pkaction | grep cups

  • The possible results are YES, AUTH_SELF(_KEEP), AUTH_ADMIN(_KEEP), NO. Returning a result is final. Returning null will continue checking other rules.

  • Put your rules in /etc/polkit-1/rules.d/*.rules. (You can check everything in one giant addRule, or you can have a separate file and separate addRule for each program; it doesn't matter.)

KunalSin9h / X11 Forwarding.md
Created August 17, 2023 11:20

Tech-savvy users know you can easily connect to a Linux server using various secure shell (SSH) clients. If you prefer – or are required – to use a tool with a graphical user interface (GUI), the solution is X11 forwarding.

What is X11 forwarding?

X11 forwarding is a mechanism that allows a user to start up remote applications, and then forward the application display to their local Windows machine. It enables you to run GUIs from a local server. It’s essentially remote desktop software that looks better on your screen and is easier to work with.
