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 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
