Simple DynDNS server

This is a simple DynDNS server implementation that builds on the Knot DNS server.

Features

Register a new domain:

$ curl -4 'http://localhost:3000/register?domain=myname'
{
	"domainName":"myname.test.test",
	"token":"ecf43b7659fc09d81c4b55ded31d6b0b",
	"message":"DNS record is not served until first DynDNS update."
}

Update DNS record:

curl -4 'http://localhost:3000/update?token=ecf43b7659fc09d81c4b55ded31d6b0b&ip=1.1.1.1'
{
	"message":"Updated."
}

WARNING: You need to use a proxy that handles authentication and authorization!

Dependencies

• Knot DNS server - Open source DNS server developed by the Czech domain registrar
• MongoDB - NoSQL database (unless you use the memory database, which is NOT recommended)

Running

Setup: npm install

sudo node index.js

Configuration

This software expects config in a file called config.json. In case this file not exists, it is copied from config.json.defaults. For all config options, look at config.json.defaults.

Database backend: the default database backend is "memory". It is volatile, the code contains a lot of linear searches, therefore it is suitable for testing only. To use MongoDB, change it to mongodb.
