dynhost

dynhost is a tiny CLI that updates a dynamic DNS record (DynHost) for a domain hosted by OVH. It relies on icanhazip.com to retrieve the public IP and calls the OVH "API" to perform the update.

Usage

This tool expects the following environment variables:

DYNHOST_USERNAME: DynHost username
DYNHOST_PASSWORD: DynHost password
DYNHOST_HOSTNAME: the domain to update

To update the dynamic DNS record, run:

dynhost

That's it!

Other commands

You can print the version by running:

dynhost -V

Systemd integration

You can find two configuration files for systemd to automatically run dynhost (every hour by default).
