title: Stop sharing a port on Ngrok
body: <p>The <a href="https://ngrok.com/usage" rel="nofollow noreferrer">Ngrok documentation</a> mentions this example to share a local port on Internet.
  Example: Open port 80 on your local machine to the internet</p>
  <pre><code>$ ngrok 80
  </code></pre>
  <p>How do I stop sharing this port if I would not want it to be accessed on the internet any more&gt;</p>
