Knoppix 3.9 from CD works well (including my scanner that did not run with 3.8.1).
But after installation (Debian like option) on the HD with knoppix-installer my connection to the local area does no longer work.

When I try to set up my printer I get a message "unable to run cups".
I checked cups with KSysV; it seems working.

What can I do to correct it?
