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 [email protected]: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.
• 5. Edit your crontab. For a 5-minutes update use: */5 * * * * cd /home/$USER/dyndns && bash dnsupdate.sh

crontab -e
