Hi,
I use a headless server on which sometime, for maintenance purposes, I need to boot from a recovery or Live CD like Knoppix. Is it possible with Knoppix to activate a serial console or the ssh server at boot time?
Thanks in advance.

If your serial console is hooked up to COM1, for instance, you just use the standard kernel parameters to set the console to output to the serial console, just add:
console=tty0 console=ttyS0,9600n8
as "cheat codes".
To add the ssh server at boot, you would need to either set up a persistent image to start it, or add a knoppix.sh to the KNOPPIX/ directory on the cd that would start the ssh service and set the root password.

In order to use this option I would need the boot screen on the serial console, that it is not activated by default. I must look if there is a grub or lilo menu file to add the option to.
To add the ssh server at boot, you would need to either set up a persistent image to start it, or add a knoppix.sh to the KNOPPIX/ directory on the cd that would start the ssh service and set the root password.
This seems easier: I will test it and come back with a feedback.
