Hey! I found the answer!

The daemon sysklogd wasn't running!

In fact I found (via the webmin)

-> sysklogd
-> crond
-> inetd
-> klogd

and others daemon, who are not started when the system boots!

Is there a list of daemon to start at boot?

Ok, now I continue to fine tuning my Knoppix Box!!!

Ciao from Italy!

Marco.
