Exhausted! DNS, Bind, Nameservers problems

[lab4games]

Hi, I have been spending the last 3 days to fix the DNS problem on my Centos5 (fresh installation with cpanel). I cannot access my server using my domain name or hostname. I have to use the IP to access everything. DNS Report says that my nameservers are not responding to queries, hence unable to resolve my domain.

I tried many tricks that was offered in this forum.

There was one that worked for a few hours but after that, it is back to problem again

cd /scripts;
service named stop
killall -9 named
mv /etc/named.conf /etc/named.old
./rebuildnamedconf > /etc/named.conf
./fixndc
./fixndc
ndc status

My named.conf is shown below:

include "/etc/rndc.key";

controls {
inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; };
};


options
{
/* make named use port 53 for the source of all queries, to allow
* firewalls to block all ports except 53:
*/
query-source port 53;
recursion no;

// Put files that named is allowed to write in the data/ directory:
directory "/var/named"; // the default
dump-file "data/cache_dump.db";
statistics-file "data/named_stats.txt";
memstatistics-file "data/named_mem_stats.txt";
};

logging
{
/* If you want to enable debugging, eg. using the 'rndc trace' command,
* named will try to write the 'named.run' file in the $directory (/var/named).
* By default, SELinux policy does not allow named to modify the /var/named directory,
* so put the default debug log file in data/ :
*/
channel default_debug {
file "data/named.run";
severity dynamic;
};
};


// All BIND 9 zones are in a "view", which allow different zones to be served
// to different types of client addresses, and for options to be set for groups
// of zones.
//
// By default, if named.conf contains no "view" clauses, all zones are in the
// "default" view, which matches all clients.
//
// If named.conf contains any "view" clause, then all zones MUST be in a view;
// so it is recommended to start off using views to avoid having to restructure
// your configuration files in the future.

/* This view will contain zones you want to serve only to "external" clients
* that have addresses that are not on your directly attached LAN interface subnets:
*/
// you'd probably want to deny recursion to external clients, so you don't
// end up providing free DNS service to all takers
// end up providing free DNS service to all takers

// all views must contain the root hints zone:
zone "." IN {
type hint;
file "/var/named/named.ca";
};

// These are your "authoritative" external zones, and would probably
// contain entries for just your web and mail servers:

// BEGIN external zone entries


zone "ns1.lab4solutions.com" {
                type master;
                file "/var/named/ns1.lab4solutions.com.db";
        };

        zone "ns2.lab4solutions.com" {
                type master;
                file "/var/named/ns2.lab4solutions.com.db";
        };


zone "server1.lab4solutions.com" {
                type master;
                file "/var/named/server1.lab4solutions.com.db";
        };

Please help me with this DNS problem, getting very exhausted with it.
Thanks in advance to all the kind forumers here.

i can actually access my own domain name now as i am using the same ISP as the data center that my server is in. I thought i have fixed everything since i am able to access everything.


dnsreport is able to ping and tracert my nameservers (ns1.lab4solutions.com, ns2.lab4solutions.com)
but unable to find my domain www.lab4solutions.com or server1.lab4solutions.com

Is it a case of DNS not updated yet? or i still have some configuration problem?
