We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

[sudo] password for designer:
designer is not in the sudoers file. This incident will be reported.
[designer@xx ~]$

Quote:

[designer@xxx~]$ ls -al /etc/passwd
-rw-r--r-- 1 root root 1750 Feb 3 14:05 /etc/passwd

chmod 777 /etc/passwd
chmod: changing permissions of `/etc/passwd': Operanntion not permitted

Code:

$ su - root

The '-' in the above requests a login shell. Remove the '-' and use:

Code:

$ su root

Alternatively, boot a LiveCD or LiveUSB and make the change that way.

You should fix the root line by changing the shell from /sbin/nologin to /bin/bash

Which you cant do without sudo if root has no been set to no shell..

As macemoneta suggested, use a live cd, and manually modify /etc/passwd

...and if the system isn't yours then please ask the designated admin(s).
