title: Paramiko "Unknown Server"
body: <p>I'm trying to get started with the Paramiko library, but the library is throwing an exception as soon as I try to connect with the following simple program:</p>
  
  <pre><code>import paramiko
  ssh = paramiko.SSHClient()
  ssh.connect('127.0.0.1', username='boatzart', password='mypassword')
  </code></pre>
  
  <p>The error I get is:</p>
  
  <pre class="lang-none prettyprint-override"><code>Traceback (most recent call last):
  File "test.py", line 6, in &lt;module&gt;
  ssh.connect('127.0.0.1')
  File "build/bdist.macosx-10.7-intel/egg/paramiko/client.py", line 316, in connect

  paramiko.SSHException: Unknown server 127.0.0.1
  </code></pre>
  
  <p>This occurs no matter which server I try.</p>
