Small DynDNS script for domains registered at inwx.de

INWX DynDNS Script

This is a small bash script, which works as a DynDNS updater. It works only with domains which are registered at inwx.de. It only updates the ip record, if the ip has changed.

##Requirements

This script does not require any additional tools. All tools should be available on a regular linux system:

• curl
• sed

##Installation

• 1. Create a new directory in your home folder. E.g. dyndns.

mkdir ~/dyndns
cd ~/dyndns

• 2. Clone the files from github

git clone [e-mail]:gehaxelt/Bash-INWX-DynDNS.git .

• 3. Edit the dnsupdate.sh and fill in your login credentials.

nano dnsupdate.sh

• 4. Get the wished dns entry id from the inwx website and set it in the script. See below how to get the ID.
• 5. Edit your crontab. For a 5-minutes update use: */5 * * * * cd /home/$USER/dyndns && bash dnsupdate.sh

crontab -e

How to obtain the DNS entry ID?

First, login to the inwx website. Navigate to "Nameserver" section:

Then open the DNS entries for your domain and right-click on the entry you'd like to dynamically update. Choose the "inspect element" menue entry.

Now you should see the developer tools and a <div>-element. The number in the id-attribute's value after record_div_ is the wanted number.

Copy this ID (here: 206895961) into your script.

Alternatively you can use the INWX API to obtain the record id.
