Exploitation of back doors usually isn't necessary. Hopefully, any such weaknesses have been turned off. In any case... A number of ways exist to regain root if you have physical access to the machine. The easiest is usually to boot the system from the install media (CD, tape, etc), and once the system is up and running, go into a maintenance shell (miniroot, whatever). Just get a root prompt... Once you've got this, you should be able to mount the disk that your password file lives on, and then edit the password file to delete the encypted password. Save your changes, and boot normally. Login as root, which will then have no password. Ta-da. -- C Matthew Curtin AT&T Bell Labs - Internet Gateway Group cmcurtin@clipper.cb.att.com
