Resolve DNS issues on cpanel 11.x Beta

[jordan]

Hello,

I have come accross an issue with DNS in cpanel 11.x , where named.conf is badly configured by cpanel ,

Here is how a DNS report from dnsstuff.com would look because of this :

FAILS for SOA record
Fails for lame nameservers .

Here's how to fix it ,

SSH to server ,

Backup your named.conf file by

cp /etc/named.conf named.conf.back

then
pico /etc/named.conf

Replace

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;    
    
    // 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.

view "localhost_resolver"
{
/* This view sets up named to be a localhost resolver ( caching only nameserver ).
 * If all you want is a caching-only nameserver, then you need only define this view:
 */
    match-clients         { localhost; };
    match-destinations    { localhost; };
    recursion yes;

    zone "." IN {
        type hint;
        file "/var/named/named.ca";
    };

    /* these are zones that contain definitions for all the localhost
     * names and addresses, as recommended in RFC1912 - these names should
     * ONLY be served to localhost clients:
     */
    include "/var/named/named.rfc1912.zones";
};

view "internal"
{
/* This view will contain zones you want to serve only to "internal" clients
   that connect via your directly attached LAN interfaces - "localnets" .
 */
    match-clients        { localnets; };
    match-destinations    { localnets; };
    recursion yes;

    zone "." IN {
        type hint;
        file "/var/named/named.ca";
    };

    // include "/var/named/named.rfc1912.zones";
    // you should not serve your rfc1912 names to non-localhost clients.
 
    // These are your "authoritative" internal zones, and would probably
    // also be included in the "localhost_resolver" view above :
};

view    "external"
{
/* 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:
 */
    match-clients        { !localnets; !localhost; };
    match-destinations    { !localnets; !localhost; };

    recursion no;
    // you'd probably want to deny recursion to external clients, so you don't
    // 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

With

include "/etc/rndc.key";

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

And then goto bottom of the file and remove

}; at the bottom .

Save file and exit

then test config
service named configtest
if you have done this correctly , it should display something like this:

zone blue.xxx.com/IN: loaded serial 2007070901
zone xxx.com/IN: loaded serial 2007070906
zone ns1.xxx.com/IN: loaded serial 2007070901
zone server.xxx.com/IN: loaded serial 2007071001
zone xxx.net/IN: loaded serial 2007071001

Then restart named by

service named restart

Thats it! , your DNS should be working now .
