    Resolve DNS issues on cpanel 11.x Beta


    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 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

    pico /etc/named.conf

    HTML Code:
    include "/etc/rndc.key";
    controls {
            inet allow { localhost; } keys { "rndc-key"; };
        /* 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";
    /*      If you want to enable debugging, eg. using the 'rndc trace' command,
     *      named will try to write the '' 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/";
                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/";
        /* 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/";
        // 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/";
        // These are your "authoritative" external zones, and would probably
        // contain entries for just your web and mail servers:
        // BEGIN external zone entries
    HTML Code:
    include "/etc/rndc.key";
    controls {
            inet 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 loaded serial 2007070901
    zone loaded serial 2007070906
    zone loaded serial 2007070901
    zone loaded serial 2007071001
    zone loaded serial 2007071001

    Then restart named by

    service named restart

    Thats it! , your DNS should be working now .
