Thanks for the tip about the hosts file.  Will start fiddling with that 

As it works out I run a nameserver so I can make all the zones I want 
for my domains.

I'm actually in charge of the wiring for the Terwilliker institute.  
That fool plumber Zabladowski thinks HE's got an important job ... ?  In 
the 21st century a solid Internet connection is more important than 
installing sinks.
