Well, here's the thing. When someone tries to ping acampbell.org.uk, which one of those machines do you want the ping to use? While I suppose that I could tell two machines that they have the same name, and then only refer to one of them by that name externally, it sounds like a mess to me. I would look in /etc/hosts for both machines and see what is defined for both 127.0.0.1 and for the "real" IP address of the machine. Note: I am by no means a DNS expert. It just seems awfully strange to me to have two machines believing they have the same name. While I can't think of any exact reason this would cause trouble, I have this gut feeling that it would. -- monique -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
