Halt and reboot permissons for normal user

Hi

On my box, if I want to reboot/halt I have to issue this command as a superuser which is quite annoying. Which user group has these permissions and how do I grant these permissions to a particular group?

Thanks

do a ls -l /sbin/shutdown and see which group has permissions. it's root on my pc. just add the user name you want to be able to issue the shutdown command in /etc/group on the first line like this:
root:x:0:root,<username>

This may not be a "perfect" solution, but it is one possible option:

Find and modify the 'ctrlaltdel' line in your '/etc/inittab' file to something like:

Code:

---

ca::ctrlaltdel:/sbin/shutdown -r -t 5 now

---

Create a new group for the users you wish to have this privilege (For this example, I will use 'shutdown'.)

Change the ownership of '/sbin/shutdown':

Code:

---

chown root:shutdown /sbin/shutdown

---

Change the permissions of '/sbin/shutdown':

Code:

---

chmod 750 /sbin/shutdown

---

Add 'shutdown' to the group list of each user who is to have this privilege.

I tried this thing but now I get this error:

Code:

---

apoorv@chandraghanta ~ $ halt
sudo: can't open /etc/sudoers: Permission denied
apoorv@chandraghanta ~ $ sendmail: Cannot open mail:25

---

I even tried changing the permissions of /etc/sudoers but nothing worked out.

did you do this step?

Code:

---

chmod +s /usr/bin/sudo

---

if so then try manually modifying permissions for /etc/sudoers

chmod 777 /etc/sudoers

or 755 to deny write access but allow read for group and others.
