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.
