Update DNS settings using the Schlundtech XML-Gateway.

Project Description

This packages provides a way to update DNS records programmatically, for customers of Schlundtech, using their XML-Gateway.

Many thanks to for doing the heavy lifting of figuring out how to talk to the XML-Gateway in a way that actually makes it do what we want.


First, you need to create a subdomain with an A-record in your domain, say

Then you can use the command-line utility provided by this package, like so:

$ schlund-ddns --username USER --password PASS

(See ddns-update --help for more configuration parameters, e.g. the context that you were told to use when applying for the XML-Gateway.)

Alternatively, set up the provided cgi script schlund-ddns-cgi to provide HTTP access. You’ll need to provide username and password using a configuration file and then passing that file’s path as an environment variable. Here’s an example apache configuration snippet to do this:

ScriptAlias /dns-update /path/to/ddns/schlund-ddns-cgi
<Directory /path/to/ddns/>
  SetEnv DDNS_CONFIG /path/to/ddns/config
  SetEnv PATH_INFO /

  AuthName "Dynamic DNS"
  AuthType Basic
  AuthUserFile /path/to/ddns/htpasswd
  require valid-user

The configuration file is a standard ini file and should look like this:

username = USER
password = PASS

The HTTP protocol is modeled after the one from NoIP, that is, clients should perform a request like this to trigger a DNS update:
