If there were every cracker in the world would have a field day.



Your only option is to reinstall the operating system from scratch.

Answer 6

Boot into the system at the physical console. Go into single user mode (check the documentation for your distro).



Make your way to the command prompt. Again consult the specifics for your distro.



Once there you should be able to run "passwd root" or similar to reset the password.



The physical console it ultimate power.



NOTE:



Some distros do not have a root account per se (Ubuntu comes to mind). Regular accounts are put in a super user list that are allowed to "su" or "sudo". In this case the password in question is the password of the account you are already logged in to. If you are allowed to "go super" you will temporarily assume "root" powers.
