hover-ddns

⚠️ hover-ddns currently doesn't work because hover is now enforcing the use of a second factor when logging in. See this issue for more information.

hover-ddns is a DDNS client that will update DNS A and/or AAAA records at hover with the current public IP address(es) of the machine.

This is an unofficial client using the non-supported Hover API.

It will:

1. Determine the current public IP address of the host machine
2. Authenticate against the Hover API
3. Create or update the DNS entry for the specified domain(s) and hostname(s)

It doesn't do anything beyond that and if you need more features or different services, I suggest to look at tools like lexicon.

Features

• IPv4 and IPv6 supported
• Supports public IP lookup by:
  • Using the ipify API (v4 only)
  • Using Amazon's checkip API (v4 only)
  • Using icanhazip.com (v4 and v6)
  • Extracting the address from a local network interface
• Cron syntax can be used to schedule periodic updates (first update will always be immediate after start)
• Multiple domains and hostnames can be specified. All will be updated with the same IP address info

Usage

Create a config file with your credentials and domain info (see the provided example.yaml).

For the configuration of the provider of your current IP address, you have the following options:

1. Use the ipify API:

   public_ip_provider:
     service: ipify

2. Use the Amazon API:

   public_ip_provider:
     service: amazon

3. Use icanhazip:

   public_ip_provider:
     service: icanhazip

4. Extract the addresses from a local WAN interface:

   public_ip_provider:
     service: local_interface
     interface_name: en0

Afterwards, either manually run hover-ddns:

$ hover-ddns --config config.yaml

or use the provided systemd service file:

$ sudo systemctl start hover-ddns.service

Installation

Docker
