Gandi Dynamic DNS

Cron job to auto update a DNS record when WAN IP changes using Gandi Live DNS API on Debian GNU/Linux

To install

git clone https://gitlab.com/lab.8916100448256/gandi-dynamic-dns.git ./gandi-dynamic-dns
cd ./gandi-dynamic-dns
sudo bash ./install.sh

Then configure DNS record info and API key in file /etc/live-dns/live-dns.conf

How it works

/etc/cron.d/live-dns-update

Cron job definition to check for WAN IP change and call Live DNS API to update the DNS record if necessary. By default runs the check/update script 2 times per hour, at every hour past 12 and 42 minutes.

/etc/live-dns/live-dns.conf

Configuration file for the check/update script Needs to contains 3 environment variable definitions

DOMAIN="domain.tld" : Replace domain.tld with your domain name
RECORD="host" : Replace host with the sub domain you want to update when WAN IP changes
APIKEY="Your-API-Key" : Replace with you API key generated on the Gandi web interface.

Check this page if you don't know your APIKey : https://docs.gandi.net/en/domain_names/advanced_users/api.html

/usr/local/bin/live-dns-update.sh

This the script that is called by the cron job.

This script is based on the sample provided on Gandi GitHub : mywanip.sh
