Hetzner DynDNS

A tool for updating Hetzner DNS with your external IP.

IP Scraping

This program uses a random list of 'what-is-my-ip' providers to cut down on errors.

Install

Install binaries for your system from the release page or use the install script:

# Local (current directory)
curl -s https://raw.githubusercontent.com/Mario-F/hetzner-dyndns/master/install.sh | BINDIR=./ bash

# Global
curl -s https://raw.githubusercontent.com/Mario-F/hetzner-dyndns/master/install.sh | sudo BINDIR=/usr/local/bin bash

Usage

1. Test external IP with: ./hetzner-dyndns myip
2. Obtain your API-Token from Hetzner DNS managment site.
3. Fetch your domain record ids with: ./hetzner-dyndns --token 'your-api-token' records
4. Call update with record ID: ./hetzner-dyndns --token 'your-api-token' --record 'domain-record-id' update

There is also a docker image available: docker run --rm -it ghcr.io/mario-f/hetzner-dyndns:latest myip

IPv6 (Experimental)

IPv6 support can activated with --version ipv6, with flag set all commands will work with IPv6.

Due the lack of testing possibilities this mode is considered experimental at this moment!

Development / Debugging

There a serveral ways to easy start development and using live debugging provided by delve

VSCode integrated Console

The provided launch.json has a debug task Launch File predefined, just hit start and it should run with the args provided in launch.json.

VSCode external Terminal

A more advanced way to test in an external Terminal is provided by the External Debugging launch config and ./debug script:

1. Execute debug script with optional arguments: ./debug --token super-secret-token records
2. Start the External Debugging session in vscode

Unfortunately the order is importend because vscode does not try to automatically connect after start.
