I'm running FC3. Just to experiment, I tried the latest CD of Knoppix, booting and running from a CD. However, now when I boot FC3 normally, the network host name is changed from localhost.localdomain to knoppix.twu.edu, and the system doesn't recognize that host, suggesting that I add knoppix.twu.edu to the /etc/hosts file. I don't want to do that. How did Knoppix change my network host name , and how do I change it back to localhost.localdomain? I've gone into Network Configuration, and found the localhost there, and I save. Then it shows me as localhost. However when I reboot, I'm back to knoppix.---.--- Suggestions? Jack
