There is plenty of ways, how to recover forgotten Linux password. My method is:
1. Burn Knoppix Linux CD (See www.Knoppix.org website)
2. Start the system useing just burned CD.
3. In console window type:
[code]sudo mount -o remount,rw [/code]
4. Navigate to your Linux system folder – /etc/
5. Open the file named shadow and delete hashed password data from the Root user record or copy some known hashed password from some known user record to the Root user record.
