regular users using halt


back a few months ago when i was running mandrake 9.1, any user on my computer was able to open a command prompt and issue the halt, reboot, and shutdown commands. after switching to debian, those commands are reserved for the su.

i tried copying "halt" and "reboot" to /usr/bin and changing the permissions (...it made since at the time) but i had no luck.

thanks for your help.

Install the SUDO package. With SUDO you can define which users/groups are allowed to run certain commands (you can specify the commands) with different (for example root) permissions. You can even specifiy whether they have to enter a password when they execute a certain command.

I had the problem that I had to switch to my root account to shutdown my pc. Now I can just type "sudo shutdown -h now" in my user account.

Do a Google search on 'sudo' to find more information.

Setting User ID for /sbin/halt, like ToniT suggests, allows you to shutdown your computer as normal user using the "halt" command (and you can reboot with Ctrl-Alt-Del). But just for the fun of it, here's how to use Sudo to achieve the same thing:

First, you'll probably want to use nano as your system's default text editor. Do "update-alternatives --config editor" and choose nano's number from the list. Then edit ~/.bash_profile and add these two lines:
Code:
EDITOR=nano
export EDITOR
And while you're editing ~/.bash_profile, you can also add some command aliases:
Code:
alias   halt="sudo /sbin/halt"
alias   reboot="sudo /sbin/reboot"
Then logout and login again so that the changes in ~/.bash_profile take effect.

Next, "su" to root, do "apt-get install sudo" to install the Sudo package, and then type "visudo". Now the /etc/sudoers file should open in nano. Type the following line to the bottom of that file (replace "username" with your username):
Code:
username   ALL = (ALL) NOPASSWD: /sbin/halt, /sbin/reboot
Then exit nano saving changes. After doing this you should be able to use the "halt" command as normal user to shutdown computer and the "reboot" command to reboot.
