One of the first things I do when having a problem like this is try to
telnet to the port of the service I'm having trouble with, so in windows
try "telnet knoppix-host-or-ip 22", you should get the something like:
Escape character is '^]'.
SSH-2.0-OpenSSH_3.8p1 Debian 1:3.8p1-2

You should also be looking in /var/log/auth.log to see if you can see
anything. Failing that, try running sshd in debug mode - 
"sshd -d -p 2000" on the knoppix box, then use another box to ssh to
port 2000 of the knoppix box.

Cheers
