    Exclamation Recover root password

    Hi all!

    I am trying to access an old ubuntu server machine but I don't know the root pass.
    I tried to hold shift while opening and then it gave me the Lilo boot console with no recovery options so I wrote "Linux single" but nothing happened. It opens but I don't have user/pass info.
    Any clue what can I do? I don't have cd or any other info about ubuntu version etc.
    Physical access to machine is my only path.

    Thanks in advance

    I'm not gonna give hacking instructions, only use this when you really forgot your OWN root password.
    I'm not responsible for any consequences.

    Boot with in the grub cmdline
    Code:
    init=/bin/sh
    And use
    Code:
    passwd root
    to change the pass.

    you can reset the password but not recover it. The encryption is one-way.

    @agillator
    boot: Linux init=/bin/sh didn't work
    It returns me not such an image
    It boots only with "Linux" but this is a normal boot.
    The machine runs Ubuntu and has LILO boot manager.
    Any ideas how to reset the root password?

    Which Ubuntu is it? You can try and boot with one of LiveCD distros, mount root partition and change hash in /etc/shadow file for root user.

    Surely must be a very old version.

    No user or root account on the machine
