The other way to do it is to not touch the shadow file.
*remove the computer from the network while doing this*
mount up the partition and add in a user to your /etc/password file
with a UID of 0 and a GID of 0 (I usually use Tux)
Then save the file and reboot.
When you are asked for the user put in the one you just created (eg
Tux)
that should let you in without a password, then since you are root you
should be able to change the root password to something you know.
Just make sure you remove the temporary user (Tux) otherwise you will
cause all sorts of security issues.
*add the computer back to the network*
Later and happy hacking

Ok.
So you locked it up :-)
check a system, where you have a known password, copy the /etc/shadow
file, it
should contain a line for root user's password, encripted :-) put it
on a
floppy ..
Get a boot-cd (from the distro, or redhat or fedora or etc...) and
reboot the
puter with it.
mount the now diabled system somewhare, the boot-disk rescue option
should
have an option to do so. If not, just choose a terminal option, and
mount it
somewhare.
edit the systems /etc/shadow file by pasting the (known but encripted)
password over the existing one. save, the reboot.
Hopefully now the system has the same password you had in the other
system.
The JohnTheRipper option, against a good password could take years :-)
