Dear all



I have a local dns server for resolving my local web servers. and also i want the local dns server should able to act as dns server for resolving public domains also.


My problem is the named gets hanged, i mean it no longer resolves local domains . and it resolve only public domains . Please help me..

Below is my setup


I am having a system with Redhat Linux 9 installed and installed bind rpm

and my /etc/named.conf file looks like this

// generated by named-bootconf.pl

options {
directory "/var/named";
forwarders { to public dns server ip; };
forward only;

/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};

//
// a caching only nameserver config
//
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." IN {
type hint;
file "named.ca";
};

zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};

zone "mydomain.ernet.in" IN {
type master;
file "mydomain.ernet.in.zone";
allow-query { any; };
};

zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};

include "/etc/rndc.key";


and it has only zone file for my local domains

mydomain.ernet.in.zone

the contents of zone file are

$TTL 86400
@ IN SOA mydomain.ernet.in. root.mydomain.ernet.in. (
2005080202 ; serial number
28800 ; refresh H=hours
14400 ; retry M = minutes
3600000 ; expiration W=weeks
0 )


@ IN NS mydomain.ernet.in.

@ IN A 172.16.7.11
www IN A 172.16.1.100
maths IN A 172.16.16.9

Your DNS is configured to forward all requests to the forwarder IPs and never to use the local resolver.

If you want to use forwarding to resolve unknown domains, add

to each zone in /etc/named.conf. This will disable forwarding for the zones you have hosted on your local DNS server. if you want to disable forwarding entirely, remove the forward and forwarders entries from the options {} clause.
