cname?

[Danny Mayer]

There is at least one bug here.

The error message is coming from the notify code, specifically
sysnotify_ns().  From the look of it, rip is trying to notify itself.
That's a bug, as it shouldn't try and notify itself. sysnotify_slaves()
should be skipping ns with its own name in it.

The particular reason that you see this is that rip.psg.com is not the
same as the mname listed in the SOA and tries to notify all other
nameservers listed in the zone.  I assume that you set up rip's
named.conf file to say that it's the master of the eg. domain.

I don't know why the nlookup that the code does on the NS name
results in it getting a CNAME result.  Mark may be able to say more.
Do you have any CNAME's in the zone?
