Logging off from bash

[Salzi]

Hello everybody,
is there a way to log off root from bash (text-console) so that nobody else can get access to the local system. Using exit or logout command doesn't have any effect.
I run Knoppix from CD with a permanent home-dir and custumized knoppix configuration.
Passwords for user root and knoppix are set.
Thanks for answers

Try man securetty since this restricts which terminals that root can be accessed.
I hope this helps.
