title: Format for connecting to rackspace via CyberDuck CLI
body: <p>I'm struggling to get a simple test of the cyberduck cli working from my computer to rackspace. Looking at the how-to (<a href="https://trac.cyberduck.io/wiki/help/en/howto/cli" rel="nofollow noreferrer">https://trac.cyberduck.io/wiki/help/en/howto/cli</a>) it shows this as the format: <code>rackspace://&lt;container&gt;/&lt;key&gt;.</code></p>
  
  <p>The test I am doing is as follows:</p>
  
  <pre><code>duck -username my_username -password my_api_key --list rackspace://test/my_api_key
  </code></pre>
  
  <p>"test" is a directory in the CDN off of the root. Trying this generates this message:
  Interoperability failure. Java.lang.NullPointerException. Please contact your web hosting service provider for assistance.</p>
  
  <p>I've also tried: <code>duck -username my_username -password my_api_key --list rackspace://test/</code></p>
  
  <p>and received the same results. </p>
  
  <p>What is the correct formatting? What am I doing wrong?</p>
