Hi all,
I need help (at lest a link) as to how to recover my root password.
I'm using SL6.2. The password I remember by heart is no longer
accepted, neither for the su command nor for sudo.
Thx
While you cannot "recover" the root password, if you have physical access
to the machine, you can bypass it, login as root and reset the password:
remove the boot disk from problem machine, attach it to a 2nd computer,
mount the root partition, go to root/.ssh and install your ssh key. unmount,
reassemble problem computer, boot, ssh into root, done. While the boot disk
is mounted on the 2nd computer, in addition to installing the ssh key,
you can also reset the password (edit /etc/shadow) or setup "sudo" for
password-less "sudo root" (recent Ubuntu are setup this way, you never actually
use the root password to login into root).
If you remember the BIOS password, or never set one,
you can boot from an install or rescue disk/memory stick,
and do that "second computer" stuff without moving the
disk to another machine.
