root password recovery - Suse 10.2.1
 

Hope you can help

Short version:

Ex employee logged into to box and changed the root password, trued to start in single user mode, but not coming right

Long version:

* Loaded up grub
* Typed the following in Boot Options:
init=/bin/sh
* Takes me to a prompt where I then enter the command "passwd"
* Returns with a "command could not be found" output

Tried changing the directories to /usr/bin and /sbin but didn't work either, any ideas?

Not sure what you mean by "not coming right", but instead of going through Grub, boot from your CD/DVD media. Go into "Rescue" mode. From there, you'll be able to mount the hard drive. You can try to run the "passwd" command from there (you'll be in as root at that point), or you can manually edit the /etc/shadow file, and remove the password for root.

And alternative is to find said ex-employee, and threaten them with bodily harm, until they tell you the password. :)

First things first, I'd specify
...as the shell. Be explicit. the system knows very little about itself at this stage.

That gives you a shell, and virtually nothing else, but the filesystem is still mounted read-only. So, next do this:
That remounts the filesystem read/write.

Now
Set you password, and (important) remount as read-only:
Hit the reset button.

Another option is to boot with a live cd, mount the partition your system is on in a folder somewhere and then chroot into it.
That suggests that /usr is on a separate partition that has not been mounted. Mount everything in /etc/fstab with mount -a
