Can someone help me by explaining how I can overcome the following error message:- Could not look up internet address for x1-6-00-11-2f-35-38-bf. This will prevent GNOME from operating correctly. It may be possible to correct the problem by adding x1-6-00-11-2f-35-38-bf to the file /etc/hosts. It's my first day using Fedora and i'm totally new to Linux. Thanks, Chris
