I get this:

[root at dns named]# nsupdate -d
> update add superdude.twu.edu. 86400 IN A 192.66.66.65
> send

Found zone name: twu.edu
The master is: dns.twu.edu

So it's being refused.  Ok, I need to add the IP address of the primary
master to the allow-update section of the master zone file in
/etc/named.conf.  That works.  Why doesn't it allow updates from itself by
default?

What happens when you run nsupdate with the -d (debug)
command-line option?
