Hi, im new here and I've got a big problem!
(I'm from Austria and so my English isn't perfect and so, please don't wonder !)
Yesterday I found my old Knoppix 3.1 and I had to run it immediately. 5 Minutes later i recognized, that I can't get superuser access!
I tried: sudo su
Answer: knoppix is not in the sudoers file. This incident will be reported.
I tried: su
password: root
result: su: Authentication failure
Sorry.
I tried: su
password --> I tried all possible passwords which could be correct! Allways the
same error.
I searched for the answer in more than ....ähm.... (i don't really know how many forums i had visited, but I know that it might be a number of at least (!) 20) forums. Now I'm here and hope getting the answer for my problem! (Was that correct English? , i hope so!)
You Linux guys are really nice and i hope you can help me ot get out of that mess!
Distribution: Slackware 11, Solaris 10, Solaris 9, Sourcemage 0.9.6

Hello!
I'm not so familiar with Knoppix 3.1 (you should download one of the latest ones 3.8, 3.9), but if I remember correctly, there should be a knoppix menu in K-menu or next to K-menu. If you find the menu, there should be a root console or root shell button there. (I think it's the first one from the bottom) when you get that console you get immediate root access. If that doesn't work, try:
Knoppix root password:
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." http://www.knoppix.net/oldwiki/?pid=273
