JAForbes / cf-ddns

A dynamic DNS systemd service for cloudflare.

cf-ddns

A node.js systemd service that periodically updates a DNS record to match the current external IP of the current server.

How?

Runs as a systemd timer every 5 mins.

The service simply fetches the latest ip from icanhazip.com and then creates or updates a DNS record using the Cloudflare REST API

All the credentials are stored in the .env file. A no login user will be created named cf-ddns which runs the service.

Installation

⚠ All commands should be run from the root directory of the project.

• Run sudo ./systemd/install.sh to install/refresh the service.
• Run sudo ./systemd/logs.sh to follow the service logs.

Problems?

If I canhazip.com ever goes away, this script will break - yay!
