User Permissions

[F_]

Hi Everyone,

I have a computer that has several normal users (i.e., not root). I would like each of these users -- who all use the Xfce desktop -- to be able to do the following things without having to use root privileges:

• Power-off the computer
  
• Adjust wifi-settings (e.g., anything iwconfig and wpa_supplicant/wpa_passphrase can do)
  
• Mount USB sticks and CD-ROMs
  

Can someone let me know what I need to do in order to be able to have my normal users do these things?


Thanks in advance,
-F.

If you are using wpa_supplicant, you can use wpa_gui to set the settings of the WiFi without root rights.

If users should be able to use e.g. "halt" or similar to power-off the PC, the sudoers file (man sudoers) should be helpful for you.

Xfce used to have simple setuid helpers for shutdown/etc. Those have been removed; you have to use policykit now.
