I have installed knoppix 3.8 to my harddisk.
I would like to change the user passwords (knoppix & root).
When i try to change the knoppix password:
passwd knoppix
The system want the old password but i don't know the old password from user knoppix.
(I installed knoppix new as live cd version. I don't set a any password. Exist an default passwort?)

many thanks
