Hello All:
           My problem is as follows: when I enter the command hosts
ns1.moontech.org I receive the message, not found 2(serverFail).  Also,
when I execute the command rndc reload, I get the response: connect:
connection refused.

Note: I registered my domainname with netsol.com.  I setup my primary
and secondary servers,forward mapping and reverse mapping zones.  I have
no idea how to get named working.  Also, I'm runnign RedHat Linux 7.1.
Named is installed on my two servers.

If you need more info let me know

Thanks Ezra Taylor

make sure your "firewall" settings allow incoming dns queries (port 53 tcp
and udp).

rndc works over port 953, so one would need to open that one as well.

1. DNS forwarding query from DNS newbie !

Hola from Barcelona,

I'm pretty new to the DNS scene and am after a little bit of advice on
an issue I have (using Solaris 8, BIND version 8.2.2-P5)

I have a DNS primary (HOST1) with connections both to the external
internet and an internal intranet.  Everything is working fine both
for internal and external name queries when all zones are served from
this nameserver.

However I am trying to configure one particular external zone so that
the zone database is held on another internal host (HOST2 - There is
no external connection on this host).  The theory is that an external
query for this zone will come to HOST1, which in turn will query HOST2
for the name resolution.

To do this I have setup a 'type forward' on HOST1 for this domain,
syntax is below:

zone "bluefish.com" in {
        type forward; forward only;
        forwarders { 192.168.20.20; };

This seemed to be working fine, name resolutions appeared to be
successful until I came across a slight problem.  The external
resolution only works when the information is cached on HOST1.  Once
the entry has expired (TTL has been reached), external name resolution
fails.  The only way to get it working again is to run a nslookup for
the domain directly on HOST1 (recaching the information), then
external resolution works again until the next expiration.

The TTL is currently set at 100 (Low for testing purposes).  

Can anybody advise me how I can set this up so that an external query
is resolved through HOST1 querying HOST2 when there is no name
information in HOST1 cache ?  Should I be using a different 'type'
from forward ? Or is the only way to get around this problem to set up
HOST1 as a secondary to HOST2 for this domain.

Any help on this much appreciated !

Gracias,

Don Robn
