Re: DNS: named ignores "forwarders"

Glynn,

One of the the named.boot file I tried is like this.
;+++++++
directory /var/named
cache . named.ca
primary 0.0.127.in-addr.arpa named.local
forwarders 192.168.168.102
;+++++++

The named.ca file has nothing in it:
;+++++++
; cleared for testing
;+++++++

resolv.conf has:
;+++++++
nameserver 127.0.0.1
;+++++++

Is there any other things that I should check?

Thanks for your help.

Andy

Yes, it works.

Are the names which are missing from the 5.1 box in one of the domains
for which it is authoritative?

The `forwarders' directive won't have any effect upon these. If named
receives a query regarding a zone for which it is authoritative it
will provide a definite answer. If the name isn't in the zone file, it
will return a negative response; it won't try to forward the query
elsewhere.
