devDNS

Over the past year and a half, I have been hacking my way around the undocumented devRant auth/write API. At the request of devRant's creators, this API must not be documented due to the way logins work on the platform. That is besides the point. I have been working on a little project called devDNS over the past few days that uses this undocumented API. Why must I be so bad at writing intros?

What is devDNS

devDNS is a devRant bot written in python. It will serve any valid DNS query from any user on the platform. A query is just a comment in one of the following forms:

@devDNS example.com

or

@devDNS MX example.com

Of course, MX and example.com are to be replaced with the domain and entry of your choosing.

devDNS was inspired by @1111Resolver, and the source is available on GitHub.

How it works

The Python script behind devDNS is very simple. devDNS does the following every 10 seconds:

• Fetch all new notifs
• Find only mentions
• Spin off a thread for each mention that passes a basic parser (Is the message 2 or 3 words long)
• In the thread, check if the message is a control message (allows me to view the status of the bot via devRant)
• Check if the request matches a required pattern
• Call dnspython with requested record and domain
• Receive answer from a custom PIHole server with caching and super low latency
• Send a comment with the results to the requester

Thats it! Super simple, and only two days from concept to reality.

Where is this hosted?

This program is hosted on a raspberry pi laying in my room running docker. I also have Portainer set up so I can easily monitor the bot from my phone over my VPN.
