My internet does not work after knoppix 3.9 install

I just installed knoppix 3.9 on my home PC; I try to do apt-get or to use kpackage, but to no avail. It would not even connect to the internet. I can not access web-pages. Is there a way to setup network such that I can get my internet up and running?

There is a switch linking my two machines. The mepis machine runs fine, but my knoppix machine doesn't. I have tried dsl linux on that machine, and even from the livecd, it accesses the network.

I am put back that there is no synaptic. kpackage is a little too difficult for me to use in terms of disabling the sources like non-us debian, that is not required.

Is there a step by step way of making network successful?

We have cautioned new users from installing Knoppix to the HD without first being aware that it might not work for them http://www.knoppix.net/wiki/Hd_Install_HowTo. You have run into a known issue with Knoppix 3.9 HD Installs in that it breaks networking.

The bug is documented as #15 http://www.knoppix.net/wiki/Bugs/3.9-2005-05-27 and can be resolved by entering the command as root user:
ln -s /etc/init.d/ifupdown-clean /etc/rcS.d/S18ifupdown-clean
