</code>

Add this code to ''/opt/hostinggl/update_cluodns.sh'' and ''chmod +x /opt/hostinggl/update_cluodns.sh''
<code>
#!/bin/bash

HOSTNAME=`hostname`
URL="https://hosting.gl/modules/servers/cloudns/api.php?action=update%26host=${HOSTNAME}"

if [ "/opt/named.conf.updatetime" -ot "/etc/named.conf" ]; then
        curl $URL && touch -r /etc/named.conf /opt/named.conf.updatetime
fi
</code>

Add cronjob
<code>
# Sync DNS to master.ns.gl
* * * * *       sh /opt/hostinggl/update_cluodns.sh
</code>

== DNSSEC ==
Add hook to unset NSEC3 when DNSSEC is enabled, because otherwise it cannot be transferred to the DNS slave server.

Put script in ''/opt/hostinggl/unset_nsec3.php''
<code>
#!/usr/local/cpanel/3rdparty/bin/php -q
<?php

// Get decoded input.
$input = get_passed_data();

// Declare return variables and set their values.
list($result_result, $result_message) = unset_nsec3($input);

// Return the return variables.
echo "$result_result $result_message";

// Perform the hooks action, using the decoded input.
function unset_nsec3($input = array()) {
    // Insert your actions here.
    $domain = $input['data']['args']['domain'];
    system("whmapi1 unset_nsec3_for_domains domain=$domain");

// Set success and failure messages.
    $result = "1";                            // This Boolean value is set to fail.    
    $message = "This is an error message.";   // This string is a reason for $result.

// Return the hook result and message.
    return array($result, $message);
}

// Process data from STDIN.
function get_passed_data() {

// Get input from STDIN.
    $raw_data;
    $stdin_fh = fopen('php://stdin', 'r');
    if ( is_resource($stdin_fh) ) {
        stream_set_blocking($stdin_fh, 0);
        while ( ($line = fgets( $stdin_fh, 1024 )) !== false ) {
            $raw_data .= trim($line);
        }
        fclose($stdin_fh);
    }

// Process and JSON-decode the raw output.
    if ($raw_data) {
        $input_data = json_decode($raw_data, true);
    } else {
        $input_data = array('context'=>array(),'data'=>array(), 'hook'=>array());
    }

// Return the output.
    return $input_data;
}
</code>

Run command to add the hook
<code>
/usr/local/cpanel/bin/manage_hooks add script /opt/hostinggl/unset_nsec3.php --stage post --category Cpanel --event UAPI::DNSSEC::enable_dnssec --manual
</code>
