[Solved] Add group to Sudoers file

pedro_sland · 2011-05-20 12:08:26

Hi everyone,

I feel this is a very stupid newbie question. I am trying to give a user access to sudo. I have two lines uncommented in /etc/sudoers:

root ALL=(ALL) ALL
%wheel ALL=(ALL) ALL

I am using visudo but it edits with nano.

I have tried to add this user to the wheel group (usermod -G wheel -a peter).

Do I need to run a command or reboot?

This is the result of the groups command so I think I have added the user to the group.

# groups peter
wheel peter

you have to use

gpasswd -a peter wheel

. after that you have to log out / in.

To be precise: Peter has to log out and in again.

Thanks! That worked great.

I'm confused now though. What exactly does "usermod -G" do and what does "gpasswd -a" do? I did man and google it but I wasn't any clearer about the difference.

hcjl · 2011-05-20 12:55:26

in your first post your wrote groupadd -G.

for the rest

man gpasswd
man groupadd
man usermod

and this https://wiki.archlinux.org/index.php/Us … management

I did write groupadd! I know what that does. Man tells me there is no -G for groupadd so I'm certain I didn't do that. I meant usermod -G. I've read the man pages again but as far as I can understand, "usermod -G wheel -a peter" should have worked. What am I missing?

problem is solved, please mark as [SOLVED]

@roygbiv
While the problem is solved I refrained from marking it as such as I was hoping someone would answer my question in #6 (it was a deliberate choice not to mark it as solved).

The command is correct and should have worked as expected.
