cannot login as root /etc/passwd mistake


Hello!

I'have make a big mistake in my /etc/passwd file, i'have removed the r to root and saved the file, and.. Logged off ..

There is the currently line of the root user in my /etc/passwd
oot:x:0:0:root:/root:/bin/bash

And.. When i'want to log in root

swen@TupperWare:/etc$ su root
Unknown id: root


And, wen i'try to log as: oot

swen@TupperWare:/etc$ su oot
Password:
su: Authentication service cannot retrieve authentication info.
Sorry.


How i'can repair this without shutting down the computer, and mount the harddisk in another box?


Thanx


Swen

just reboot the machine and boot to single user mode. add "single" to the end of either the lilo boot coption, or the grub command before running it and that should log you in fine, then you can just edit passwd directly. then just run "init 3" to boot the thing all back to normal.

I tried to boot into single user mode and i didn't have any root privelages. I tried

linux single
linux -s

If i would try and log in with root, i would get asked the pass...
When i logged in with my account wouldn't have root privelages. What else do i need to do??

One more thing that i noticed is i was still able to switch about tty's but when i would log in it was like 'myname'@(none) or soemthing.

thanks
