sudo: What's the output of "cat /etc/hostname" and "cat /etc/hosts"? static/dhcp: Do you have a dhcp server on which you can set reservations and other options? If, yes, you can either specify that the dhcp server hands out a specific address to valhalla or set valhalla up with a static ip address and specify that the dhcp server not hand out that address. (If you use a static ip address you also have to set a default route for it to be able to access the internet.) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
