 |
|
Sorry im nob 
I can't poweroff or shutdown the system, not enough rights.
In sudoers file I wrote ALL=ALL NOPASSWORD:/sbin/shutdown, or something. Added me to the wheel group, let %wheel do ALL. No change.
Seems it's simple to configure but i just dont know how   |

Hi,
I assume you're trying to shutdown as a regular user and not as root. Is it working fine with root?
From my /etc/sudoers:
| Code: | # User privilege specification
root ALL=(ALL) ALL
# Uncomment to allow people in group wheel to run all commands
# %wheel ALL=(ALL) ALL
# Same thing without a password
# %wheel ALL=(ALL) NOPASSWD: ALL
# Samples
# %users ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
# %users localhost=/sbin/shutdown -h now |
I assume you'll need:
| Code: | | %wheel ALL=(ALL) NOPASSWD: ALL |
to be set 
This lets you run ALL with NOPASSWD as in %wheel, also if you want to give %wheel users just the shutdown possibility, you'll need:
| Code: | | %wheel localhost=/sbin/shutdown -h now |
Don't set all users to be able to shutdown. If you want all users (regular users), use your %users group to do it, and add every regular user to thatone.

Danger will Robinson, DANGER!
Maybe you could post that portion of sudoers so we can take a look?

Well that's my /etc/sudoers file, what I do wrong??
| Code: | # sudoers file.
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the sudoers man page for the details on how to write a sudoers file.
#
# Host alias specification
# User alias specification
# Cmnd alias specification
# Defaults specification
# User privilege specification
root ALL=(ALL) ALL
# Uncomment to allow people in group wheel to run all commands
%wheel ALL=(ALL) ALL
# Same thing without a password
# %wheel ALL=(ALL) NOPASSWD: ALL
# Samples
%users ALL=/sbin/mount /mnt/cdrom,/sbin/umount /mnt/cdrom
%users ALL=/sbin/shutdown -h now
%users ALL=/sbin/reboot
%users ALL=/sbin/poweroff |
And here's my id:
| Code: | | uid=1000(amalghama) gid=35(games) groups=10(wheel),27(video),35(games),100(users),250(portage),440(amalghama) |
 This just kills me  |

Either I'm drunk or my sudoers file MUST work that way. But it doesn't. I can sudo as it defined in /etc/sudoers, but I can't poweroff:
$poweroff: command not found
$/sbin/poweroff: you must have administrators permissions
ps of course i can poweroff as root... |

Well here is my file so you can compare, not that I see much difference though.
| Code: | # sudoers file.
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the sudoers man page for the details on how to write a sudoers file.
#
# Host alias specification
# User alias specification
# Cmnd alias specification
# Defaults specification
# User privilege specification
root ALL=(ALL) ALL
# Uncomment to allow people in group wheel to run all commands
# %wheel ALL=(ALL) ALL
# Same thing without a password
# %wheel ALL=(ALL) NOPASSWD: ALL
# Samples
# %users ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
# %users localhost=/sbin/shutdown -h now

Looks like the only line it sees is root ALL=(ALL)ALL.
Hope that helps. I can shutdown in KDE as dale but only root when in console.
Later

Don't you need to type "sudo" in front of the command?
| Code: | | $ sudo /sbin/poweroff |

That's right, but is this good?  e.g. in redhat i can only type as a user that way: poweroff, and alas! So how can i do it in Gentoo???
Thanks!
ps btw permissions on /sbin/halt are ok, 755, if its important with the problem... |

No, my /etc/sudoers seems correct.
But a user cant reboot anyway without sudoing.
But there MUST be a way out!
Which?... |

What does "ls -l /sbin/halt" show in the RedHat box? This is from a RedHat 8 box at work:
| Code: | $ ls -l /sbin/halt
-rwxr-xr-x 1 root root 12645 Jul 18 2002 /sbin/halt
$ cat /etc/redhat-release

If | Code: | | $sudo /sbin/poweroff |
works, and you just want to use All you'll need to do is add an alias in your .bashrc file. I.e.: | Code: | | alias poweroff='sudo /sbin/poweroff' |
In order to use it immediately, you'll need to
