A simple PHP script to update Amazon's Route 53 with a new IP

php-ddns53

A simple PHP script to update Amazon's Route 53 with a new public IP.

This is a simple hack to use Route 53 as a dynamic DNS host. This is a version based on Holger Eilhard work.

Usage

It requires Dan Myers's Amazon Route 53 PHP Class to work. A version of this class is provided here.

Fill the details of your AWS account in ddns-change.php

$awsKey = "AWS-KEY";
$awsId = "AWS-ID";
$hostedZoneId = "HOSTED-ZONE-ID";
$hostNameToChangeIp = "HOST-NAME-TO-CHANGE-AS-LISTED";

Put ddns-change.php, Route53DynDns.php and r53.php files in the same folder. For a basic usage just run

php ddns-change.php

If you want to use this as a cron job with output to a log file, a basic utility script is provided for that. Fill the full path of the PHP script (and log file) in ddns-cron.sh

FULL_SCRIPT_PATH=/path/to/script

FULL_LOG_PATH=/path/to/logs
...

Now you can create an entry in crontab with the full path for ddns-cron.sh script or execute

./cron-installer.sh /path/to/ddns-cron.sh "0 0 * * *"

which will install a cron job for the user which will execute the script every day at midnight (change the cron pattern accordingly).
