OVH DynHost Updater

This Python script updates the DynHost IP, using the OVH API.

Requirements

• ovh - https://github.com/ovh/python-ovh
• ipgetter - https://github.com/phoemur/ipgetter

Installation

It is recommended to install the script in a virtualenv.

git clone <>
virtualenv venv
. venv/bin/activate

pip install ovh ipgetter

Configuration

Subdomain

The two scripts ck.py and updater.py require subdomain data.

cp subdomain.conf.sample subdomain.conf
nano subdomain.conf

You need to change :

• the zone name
• the subdomain name
• the subdomain id

This last can be retreived from the OVH API console : https://api.ovh.com/console/

GET /domain/zone/{zoneName}/dynHost/record

Access

The ovh module uses the file ovh.conf to get the access tokens.

cp ovh.conf.sample ovh.conf
nano ovh.conf

Fill the fields application_key and application_secret with the values obtained here: https://eu.api.ovh.com/createApp/

You need to generate the consumer_key.

python ck.py

The python script asks OVH server GET and PUT access to the path /domain/zone/{zonename}/dynHost/record/{id}

Follow then the instructions of the console output.

Copy the Consumer Key into the file ovh.conf.

Automatization with cron

The script will run with current user privileges.

crontab -e

Add the following line to launch the updater.py script every five minutes.

# m   h   dom   mon   dow   command
*/5   *   *     *     *     /my_path_to/updater.sh
