Thanks for your help on this Harry. I cannot get 5.0.1 to return consistent results on the one computer that sometimes brings up eth0. I can ping with this computer, but it does not return results in the browser. Knoppix 5.0.1 does not work on any of the other three because it returns only lo and not eth0 on ifconfig on these. Knoppix 4.0.2 can work with three of them consistently, just not the one using a USB ethernet adapter. This was prepared using my oldest computer an Intel Mendocino 367MHz using Knoppix 4.0.2. I think this would best be closed and I will wait for 5.0.2.
