DDnsLight

This is a little class that allows you to use a webserver to be a dynamic dns server.

Installation

Create a index.php in a folder you want to use for the update process like '/dns'. Copy the class to the folder and edit the index.php like

<?php
include_once("DDnsLight.php");

$dns = new DDnsLight();
$dns->run();

The first time you run the script, it will create a folder "storage" including a "dns.ini.php" and a ".htaccess" file. Open the ini.php file and set a password. The password will be used to authorize the update-ip process.

The second time you call the script, it will do what it was written for.

Call the dynamic ip

For simple website applications it will use the location header to redirect to a dynamic ip. To do so you need to call the site like

http://my-static-site.com/?/
http://my-static-site.com/?/a/deep/link

to simply receive the current dynamic ip, simply call

http://my-static-site.com/

this can be used for other scripts that redirect other services

Config to update dyndns as well

The class has some constants. You should only change the following to make the script also update your dyndns account

const DYN_DNS_ACCOUNT_UPDATE = FALSE;
const DYN_DNS_ACCOUNT_USER = "";
const DYN_DNS_ACCOUNT_PASSWORD = "";
const DYN_DNS_ACCOUNT_HOST = "";

Licence

Use the script as you like on your own risk.

The script originally came from here.
