OVH dynamic DNS automation in Python. For bash script, check this repository
This is a simple script that allows you to check DNS entries for a list of subdomains and replace the record if the public IP of the network in which the script is run differs from that of the record. In short, play the role of a dynamic DNS updater. Assigned to a scheduled task exploits the full power of the script. Discord notification via webhook are implemented. Original script from this Github repo.
First, you need to clone the repo, then, install pip package discord_webhook. To get it, run this command :
pip install discord_webhookNow, you can execute it.
Some configuration is needed to make it work.
The script check the IPv4 address of the given reference domain, and compare it to the given domain. If IP's are different, all registered domains in host list will be updated with IPv4 value of reference_domain.
Modify the following lines to match your domains :
domain = 'subdomain.domain.com' # Reference domain for local / public IP check
reference_domain = 'subdomain.domain.com' # local domain to checkYou have to modify subdomain.domain.com, username and password to match your subdomain address, your DynHost id and the password assigned to it.
['subdomain.domain.com','username','password'],You can add as much domains as you want, just duplicate the line above and modify the values to match your DynHost domain entry. Host are in a list.
python3 dynhost.pyThe interest of this script is to be executed periodically. The best way to do this is to create a scheduled task with CRON, or any other task scheduler of your choice.
