Which machine ? OS ? Rev version ?

It would be interesting to see the output from
   put the hostname  && ":" && hostnametoaddress(the hostname)

to see whether the hostname has been set properly (and then to see 
whether the host name to address mapping is OK).

if you're on a Mac, try opening a terminal window, and look at the 
output from
    echo $HOSTNAME
if you're on a PC, ummmm .... I forget :-) - but look at what the system 
thinks the hostname is.
