    Off hand that looks like a mess up on your part in the DNS records. All
    my computers respond, in themselves, to localhost as 127.0.0.1. The DNS
    query reports nothing found. Of course, that is on a Mandrake 10 and a
    RedHat 9 pair of machines with the DNS engine on the RedHat 9 machine.
