NodeDynDNS

Motivation

I was looking for a way to have a dynamic DNS service to my home router so I could make a game server (ARK: Survival Evolved) easily accessible to non-CS people. There already was a server I could use and after quickly searching for dynamic DNS software I decided I could develop something with appropriate use application of OOP myself. So I started this project

Project Summary

• JavaScript on node.js
• RFC 1035 compliant
• API with http basic authentication to update

Setup Instructions

• Have node.js installed
• run: npm install
• Rename conf.example.json to conf.json and make your settings (pretty self-explanatory)
• DO NOT enter the password in clear text. Instead call npm run hash. You will see what it does

Additional Notes

• Make sure you have the correct records DNS record set, so this DNS server will actually be accessed
• You can of course add multiple domains
• App must be run with root privileges to be able to bind to dns port 53/udp
• The app will drop privileges to user and group defined in the "system" dict
• If you want no http or https server just remove it from the config file
• The dot at the end of the of the domain IS REQUIRED
• The app will save the set records in storage.json
• DO NOT TOUCH storage.json, except if you want to set a specific init IP
• EXCEPT maybe to clear dns data, you can delete it

Running the app

• node .
