DreamHost Dynamic DNS updater

This is a simple script to keep a domain or subdomain always pointing to your current IP, basically turning DreamHost into a dynamic DNS provider - similar to no-ip.com or dyn.com.

It uses the dreamhost package to connect to DreamHost's API and http://ip.nfriedly.com/ to determine your IP address.

Usage

First install it globally

npm install --global node-dreamhost-dns-updater

Now get a DreamHost API key with "All dns functions" from https://panel.dreamhost.com/?tree=home.api

Run it once to make sure it works:

update-dreamhost-dns --api_key YOUR_DH_API_KEY --domain my-computer.example.com

Assuming that went well, set it in a cronjob and forget about it. Here's an example that runs the script every 5 minutes:

# Minute   Hour   Day of Month       Month          Day of Week        Command    
# (0-59)  (0-23)     (1-31)    (1-12 or Jan-Dec)  (0-6 or Sun-Sat)                
	*/5      *         *              *               *                update-dreamhost-dns --api_key YOUR_DH_API_KEY --domain my-computer.example.com

On Windows, you can set up a Scheduled Task with the same command.

On Mac you can alternatively download the excellent SleepWatcher and make it run any time you computer wakes from sleep.

Note: it currently only works on IPv4 addresses. PRs are welcome to add IPv6 Support.
