Hello. I am using Knoppix 4.0.2 live CD. I want to run my DSL's cat5 cable through a manual on/off swith, so I can physically disconnect from the internet and then reconnect at will, without rebooting. Also, I want to be able to boot without an internet connection and then get Knoppix recognize the connection upon command. Whenever I boot with my DSL modem already attached it shows up as eth0. How do I get eth0 working from the command line?
