Do you enter the correct root password? roelof's password and root's password may not be the same.

roelof · 2009-08-08 19:26:42

yep, I'm shure I entered the right password.

Ok, is a roelof member of the wheel group?

FreeArtMan · 2009-08-08 19:36:42

open /etc/group file and add to line
wheel::10:root
your user name
it should be somthing like that
wheel::10:root,roelof

Hoi,

Roelof is not member of the wheel group, only member of the user group

use gpasswd to add it, don't edit /etc/group by hand

e.g.. gpasswd -a roelof wheel

and if you are not using gnome etc.

usermod -G ...

Why not edit /etc/group by hand? I always do nano /etc/group and put my user in to groups I want.

Hi Pyntux, you can do that no problem. Just that using the tools traps any typos.

roelof · 2009-08-08 19:49:12

oke,

I will try that tomorrow.
It's now around 10 o clock in the evening.
Almost time to sleep.

1. why are you doing su when you already are root?
2. You don't need to be a member or wheel to use su
3. sounds like the wrong password
4. how exactly are you trying to use su as your user?

1. why are you doing su when you already are root?

I was only trying if it works nothing else.

2. You don't need to be a member or wheel to use su

Oke

3. sounds like the wrong password

Im sure it not a wrong password.

4. how exactly are you trying to use su as your user?

Im user roelof and enter in the prompt su
then I get a message to enter the password, I enter the password of root.

After then i get a message that the password is not correct.

Sorry, wheel is not required by Arch for su. I use BSD too and should read more!

Anyway, what's the output of groups?

Maybe a wrong keyboard layout playing up, but usually it's user error and not system error . Reset your pass, check it again, type your password in the clear so you can actually see what letters it's composed of, just to make sure.

Mr.Elendig · 2009-08-08 20:51:08

There was a bug which broke su, but that was ages ago. Been long since you updated your system?

bernarcher · 2009-08-09 08:07:55

Two quick thoughts which come up to my mind:
1) Did you also try "su -" instead of plain "su"?
2) Does the same happen with another user (just for testing purposes)?

roelof · 2009-08-09 10:40:48

Hello,

That's a lot of questions.

B : I did it and when I type the password in a terminal. Everything looks allright.
Mr. Elendig : I re-installed the system by ftp, so i migt think that that's not the problem.
Beranrcher : 1) I also try su - but problem still exist.
2) Do you mean make another su by addepting visodo file ?

loafer · 2009-08-09 10:57:51

visudo has no connection to su at all. It is used to edit /etc/sudoers, the config file for sudo. Create a new user and try "su - newuser".

This one is solved.
I gave root a password and now everything is good,
