GDYNDNS

This is a simple little application that can be set to run via whatever means you want, but all it does is simple update a synthetic dynamic dns record for a google domains domain.

Please see This URL if you don't know what I'm talking about.

Usage

Usage of ./gdyndns:
  -hostname string
        your google domains hostname to update
  -password string
        your google domains password
  -username string
        your google domains username
  -ipinfo-token string
        your IPINFO.io API Token

Installation

Prereqs:

• Go >= 1.14.0
• make

Installing:

1. clone this repo
2. cd into this repo
3. make && make install

If you use systemd (and there is a good chance you do), you can install a service for this as well using make install-service, but you will need to modify the /etc/systemd/system/gdyndns.service file with your actual information. Then, you should do a systemctl daemon-reload && systemctl restart gdyndns.timer.

Note

This uses the ipinfo.io backend to get your current IP address, so if you don't set the -ipinfo-token flag, you will be limited to 1000 requests per day (which is probably ok).

If you need up to 50,000/mo requests (which might be the case if you use this across a bunch of servers), you will need to sign up at https://ipinfo.io.

If you need more than 50,000/mo requests, you are going to have to use a paid ipinfo account 😄

Disclaimer

I am not affiliated with ipinfo.io at all, i just like their service.
