internal and external DNS servers: no addrs found for root NS ()

[Kamesh Patel]

Setup a root zone of type hint and specify a file. Create this file
respectively, under linux it should be stored in /var/named/ this file
should hold the addresses of all of the head dns servers such as the one
hosted by your IP!!! that should do the job!

e.g the zone in your named.conf file

zone "." {
        type hint;
        file "named.ca";
};

the contents on /var/named/named.ca

Subject: internal and external DNS servers: no addrs found for root NS
()


 First, I would like to say hello, and I hope everyone is fine.
Second, my question:

I setup a primary (root) and secondary internal BIND servers running on
Solaris 2.7.  Everything was running great until I decided I needed them to
answer requests for external hosts.  From your experiences, what would be
the best way to setup up my internal DNS servers, to query a primary and
secondary DNS server provided by our ISP (the ISP is currently hosting our
external DNS)?

I tried adding forwarders to my conf file, however I started receiving
messages because it cannot find addresses for the root servers.

>From what I understand, when named starts, it will query the forwarders for
the root servers addr first, and since the external NS do not exist in my
root.ca file, I receive these messages:

/var/adm/messages

sysquery: no addrs found for root NS ()

I guess you can see where Im going with this.  Maybe a little nudge in the
right direction will help me figure out the rest.

Thanks in advance!
