I'm new to Knoppix and am a Linux novice although I've played with various distros off and on for over 10 years.

I am running Knoppix 5.1.1 Live on a Gateway MX6931 laptop. My network card is recognized and apparently DHCP works as well. The problem is that I can ping IP addresses on my network and on the Internet just fine. However, I can't get name resolution. This occurs both on my network at the office and on my network at home. The networks are functioning fine for all other OSs and distros. Other OSs and distros work fine on this laptop.

When I look at all the items I know to look at, all is well.

Can someone tell me what's wrong with any of this? It all looks fine to me. It's as if there is some service that isn't running that uses the values in the resolv.conf.

The symptoms are the same on both networks. All values in various configurations appear fine. If I was using Windows, I'd do something like "ipconfig /renew". I assumed "pump -R" was similar but that doesn't work. I get an "Operation failed" message.

When I ping "www.google.com" or other known hosts, I get the "Unknown host or host unreachable"-type message.

Any help would be appreciated.
