title: Python Pysftp Error
body: <p>My code:</p>
  
  <pre><code>import pysftp 
  s = pysftp.Connection(host='test.rebex.net', username='demo', password='password') 
  data = s.listdir() 
  s.close() 
  for i in data: 
      print i
  </code></pre>
  
  <p>I'm getting an error trying to connect to a SFTP server using pysftp.</p>
  
  <p>This should be straight forward enough but I get the error below:</p>
  
  <pre class="lang-none prettyprint-override"><code>Traceback (most recent call last):

  <p>I've tried using different versions of python (mostly 2.7), I have all dependencies installed and I tried numerous sftp connections.
  I'm using OS X 10.9.1.</p>
