That may cause problems.  Eric and others can correct if I'm wrong,, but
I think you may need some of the system files that the above step will
set up in the /home/space1/aips/DA00/DIZZY/ directory in order for the
TPMON daemon to run on Dizzy.

Remember to check TPHOSTS too; this is where you define who's allowed to
connect to your TPMON daemons on Dizzy and other machines.

Check your /etc/nsswitch.conf on dizzy.  What's the order for services?
It should be:

   services:	files nis

in your case (assuming you're not using nis+).
