<p>Over the past year and a half, I have been hacking my way around the undocumented <a href="https://devrant.com">devRant</a> 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 <a href="https://devrant.com/collabs/2163502">devDNS</a> over the past few days that uses this undocumented API. Why must I be so bad at writing intros?</p>
|
||
|
||
<h2 id="what-is-devdns">What is devDNS</h2>
|
||
<p>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:</p>
|
||
<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>@devDNS example.com
|
||
</code></pre></div></div>
|
||
<p>or</p>
|
||
<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>@devDNS MX example.com
|
||
</code></pre></div></div>
|
||
<p>Of course, <code class="highlighter-rouge">MX</code> and <code class="highlighter-rouge">example.com</code> are to be replaced with the domain and entry of your choosing.</p>
|
||
|
||
<p>devDNS was inspired by <a href="https://twitter.com/1111resolver">@1111Resolver</a>, and the source is available on <a href="https://github.com/Ewpratten/devDNS">GitHub</a>.</p>
|
||
|
||
<h2 id="how-it-works">How it works</h2>
|
||
<p>The Python script behind devDNS is very simple. devDNS does the following every 10 seconds:</p>
|
||
<ul>
|
||
<li>Fetch all new notifs</li>
|
||
<li>Find only mentions</li>
|
||
<li>Spin off a thread for each mention that passes a basic parser (Is the message 2 or 3 words long)</li>
|
||
<li>In the thread, check if the message is a control message (allows me to view the status of the bot via devRant)</li>
|
||
<li>Check if the request matches a required pattern</li>
|
||
<li>Call <code class="highlighter-rouge">dnspython</code> with requested record and domain</li>
|
||
<li>Receive answer from a custom <a href="https://pi-hole.net/">PIHole</a> server with caching and super low latency</li>
|
||
<li>Send a comment with the results to the requester</li>
|
||
</ul>
|
||
|
||
<p>Thats it! Super simple, and only two days from concept to reality.</p>
|
||
|
||
<h2 id="where-is-this-hosted">Where is this hosted?</h2>
|
||
<p>This program is hosted on a raspberry pi laying in my room running docker. I also have <a href="https://www.portainer.io/">Portainer</a> set up so I can easily monitor the bot from my phone over my VPN.</p>
