I've noticed a few trends in my visitor lists. One is people looking for information about Knoppix version 6 and ssh.
As I've said before I like my Gnu/Linux a little harder. I installed Knoppix 6 on a laptop at work and ssh was not included. No server, no client.
It is included on the Live CD, and can be ran from the live cd. However when I did the install, it was not there. To get it, I had to do the following:
root@Microknoppix:~# apt-cache search ssh
root@Microknoppix:~# apt-get install openssh-client
The above commands are tested from the live cd. On an installed system your milage may vary.

I've revisited this. Running Knoppix on VirtualBox.
Knoppix 6.2, LXDE. Click the desktop menu button, and under preferences Start SSH.
Aptitude had the ssh server listed when I searched for ssh, with the sourcelist that was installed from the LiveCD
