Recover root password

[Ataraxos]

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

http://www.debianadmin.com/forgot-ro...in-debian.html should work for you, I believe.

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

init=/bin/sh

And use

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.

Which Ubuntu is it?

I don't know... How i can see this?
Surely must be a very old version.

Run this from a terminal

lsb_release -a

Run this from a terminal

lsb_release -a

I don't have access on a terminal...
No user or root account on the machine

boot with a live cd and do what is described in the link posted by agillator.
