ddregister

This code provides Dynamic DNS Registration for any hosts within your domain, which is registered through Google Domains. The code should be run as a daemon, as it checks the IP address of your NAT domain using ipify and re-registers with Google if your IP address has changed. You can set the interval for the registration. To use,

bash% go get -u github.com/djthorpe/ddregister
bash% ddregister -help
Usage of ddregister:
  -debug
    	Set debugging mode
  -dns.passwd string
    	DNS registry password
  -dns.user string
    	DNS registry username
  -host string
    	Hostname to register
  -interval duration
    	IP address discovery interval (default 1h0m0s)
  -log.append
    	When writing log to file, append output to end of file
  -log.file string
    	File for logging (default: log to stderr)
  -verbose
    	Verbose logging

The -dns.user and -dns.passwd flags are required and can be retrieved as per these intructions. For example,

bash% ddregister \
  -dns.user   XXXXXXXXXXXXXXX \
  -dns.passwd XXXXXXXXXXXXXXX \
  -host       XXXXXXXXXXXXXXX.mydomain.com \
  -interval 15s

Will run the code in the foreground and re-register your dynamic DNS entry every 15 minutes.
