title: Can't access http://localhost:3000 after setting up webrick server with rails
body: <p>I followed this tutorial: <a href="http://guides.rubyonrails.org/getting_started.html" rel="nofollow">http://guides.rubyonrails.org/getting_started.html</a> and I get to the part where you write:</p>
  
  <pre><code>rails server
  </code></pre>
  
  <p>Then, when I tried to access http:/localhost:3000 I had an "access denied" error. I already tried:</p>
  
  <ul>
  <li>accessing http:// my-ip:3000, http:// 127.0.0.1:3000, http:// 0.0.0.0:3000 (the spaces are because I'm not allowed to post links)</li>
  <li>opening the 3000 port in the firewall settings</li>
  <li>trying again from a different browser/computer</li>
  </ul>
  
  <p>What can I do to make it work?</p>
  
  <p>Thanks.</p>
