gandyndns

The purpose of this script is to change on execution the IP address of a Gandi.net DNS record (default is to change the DNS @.example.com A record) and replacing the IP with the public IP of the machine on which the code is executed. The goal is to provide a dynamic change of DNS record like DynDNS, DuckDNS, etc for Gandi.net domains.

This script was inspired by matt1's gandi-ddns script : matt1/gandi-ddns

Each time the script runs it check if the IPs in the DNS record match the current public IP and if they dont use a PUT request to apply the new IP to the DNS.

Automation : Run the script using a cron task

sudo crontab -e

And then to execute every X minutes (where X should be an integer between 1 and 59) write in the crontab :

To set multiple domains or subdomains just add multiple lines.
