php-dyndns

SchlundTech DynDNS api for PHP. Forked from martinlowinski/php-dyndns and reduced to CLI only.

The code is still ugly but does its job for now. Tested and fixed with PHP 8.2.

Installation

Prerequisites

• Contract with Schlund-Technologies and access to the XML-Gateway.
• php-cli and php-curl

Setup

1. Create a subdomain with an A-record in your domain, say home.example.com. It should have a low TTL value such that it is not cached (schlundtech only allows >=60).
2. Upload the files to your webserver. The update.php script has to be accessible from the web, for example: dyndns.example.com/update.php. HTTPS is highly recommended!
3. Copy config.example.php to config.php and adjust the settings.
4. Create the logdir and give the webserver write-access to it.
5. Set up a cron-job, fritz-box, router, ... to do a request every time the ip-address changes. The URL is http://dyndns.example.com/update.php?pass=<password>&domain=example.com&ipaddr=<ipaddr>&ip6addr=<ip6addr>

Command line

The script can also be executed from the command line:

php update.php --pass="<password>" --domain="example.com" --ipaddr="<ipaddr>" --ip6addr="<ip6addr>"
