What can I do to recover root password if I forget it.

**lakerdonald** · 01-04-2005

well, you can always:
1)boot a livecd like gentoo, knoppix, etc.
2)become root on the livecd
3)mount your hard drive

Code:

mount /dev/hda1 /mnt/hda1

replacing hda1 with the appropriate drive and mountpoint
4)chroot into your linux distro's environment

Code:

chroot /mnt/hda1 /bin/bash

replacing hda1 with the correct mountpoint
5)then do:

Code:

passwd

and whabam you should be set

Or you can boot into single-user mode. On grub do this by appending 'single' to the kernel line. This puts you directly into root without a password. All the more reason to password-protect grub.

thats why physical access to any machine must be protected if the machine is important, like a server. Mac OSX is just as easy to crack into. XP you need boot media, but with physical access anything is possible

on the grub interface highkight ur linux distro
press 'e' on the key board
u will be taken to the sub menu
here select the line that starts with the word kernel and hit 'e' again
the line will now appear in editable mode
donot delete anything from the line... go to the end of the line and add '1' without the quotes to it
"kernel ***** ro root=LABEL=/ 1"
hit enter
now u will be taken back to the sub menu
