==== Q: What is the root password? ====

A:

'''Live CD:

From the [[Using FAQ]] : there is none; in Knoppix LiveCD all passwords are locked by default.

You can set root password by going Knoppix Menu->Root Shell and typing "'''passwd'''", then enterting a root password, also there are several sections you can read dealing with this subject in KNOPPIX/README_Security.txt. You can also type "'''sudo su'''" or "'''sudo -s'''" in any console window, or use <ctr>-<alt>-F2 to get at the text console with already opened root shell.

Apparently, however, in some versions of Knoppix, if you type 'sudo -s', it will ask for a <span class="plainlinks">[http://www.diamondlinks.net/ <span style="color:black;font-weight:normal; text-decoration:none!important; background:none!important; text-decoration:none;">link building</span>] password. If you simply press return without entering anything, it will tell you 'Authentication Failed."

'''Hard disk installation:
Open a console window (monitor icon on taskbar) and use the command su then enter the root password.

If you added a user but are unable to 'su' or 'sudo' once logged in as a user, you may not have set a 'root' password during the install process. Reboot with the KNOPPIX disc, mount the harddrive partition that contains your freshly installed KNOPPIX files:
*For me it was
**'''mount /dev/hda1
*Change root to harddisk:
**'''chroot /mnt/hda1
*Then edit the sudoers file (not 'vi /etc/sudoers' because that's the OS in RAM)
**'''visudo
*For an easier editor use:
**'''EDITOR=mcedit visudo
*Then change the line:
KNOPPIX ALL=NOPASSWD: ALL
*to the username you have set up already, example:
bob ALL=NOPASSWD: All
*Reboot from your harddrive and then create the 'root' password:
**'''sudo passwd
*done
