Hi all,
My password is easily guessable. And that is my sudoer account.
I'm unable to chang my password is ubuntu.
Even if I print
passwd
It asks for my old password. and thn asks for the new password twice,
It says password has been changed. But when I relogin, it accepts the earlier password only.

Please how do i chang my password?

Run "ls -l /usr/bin/passwd". This is one of the few commands that has suid root permissions. This allows a regular user to change his own password, which requires editing /etc/passwd and /etc/shadow.

Also post the contents of /etc/pam.d/passwd and if it exists /etc/pam.d/password-common.

Post any /var/log/messages log message for when you ran passwd. E.G.
Jul 24 10:16:01 qosmio passwd[17818]: password changed - account=jschiwal, uid=1000, by=1000

I'm not certain what you mean by your sudoer account. A sudoer isn't root, and the root account is disabled in Ubuntu.
