title: paramiko Incompatible ssh peer (no acceptable kex algorithm)
body: <p>I'm getting the following error when trying to ssh to a Cisco ACS device using the paramiko library.  I've used paramiko in python without issue, and I can ssh to this box from the command line, or using putty without issue.  I've turned on debugging and copied the info here.  Please let me know if you can help me out.</p>
  
  <pre><code>import paramiko
  import sys
  import socket
  
  try:
      paramiko.common.logging.basicConfig(level=paramiko.common.DEBUG)
      sshConnection = paramiko.SSHClient()
      sshConnection.set_missing_host_key_policy(paramiko.AutoAddPolicy())
      sshConnection.connect('server',username='username',password='password')
  except paramiko.BadAuthenticationType:
      sys.stdout.write('Bad Password!\n')     
      sys.exit()
  except paramiko.SSHException, sshFail:
      sys.stdout.write('Connection Failed!\n')
      sys.stdout.write('%s\n' % sshFail)
      sys.exit()
  except socket.error, socketFail:
      sys.stdout.write('Failed to open socket\n')
      sys.stdout.write('%s\n' % socketFail)
      sys.exit()

  <p>I've made sure I have the most recent versions of pycrypto and paramiko installed.</p>
