Accessing internet, not neighborhood -???

Howdy! I'm somewhat new to Knoppix, and Linux as a whole. As I explore the OS further, I find myself digging a hole through cement with a shovel. Anyway, I installed the OS to my harddrive, and it boots great. I open Konqueror, and I access the internet no problem, but I'm having trouble setting up the network. How do I change the name of the computer(not user)? (at the bootmenu, computer name is displayed). And how do I assign (or create) a workgroup to browse from/within?

You could try Kmenu -> Internet -> Linneighborhood. To change hostname edit the file /etc/hostname as root.
