Thanks for the detailed reply. However, I get the following error:

   File 
"/nfs/02/reckoner/lib/python2.6/site-packages/IPython/zmq/session.py", 
line 725, in unserialize
     raise ValueError("Invalid Signature: %r"%signature)
ValueError: Invalid Signature: '5f4c8fc192935e9c612c61660ead7e7a'

I followed your instructions exactly. What am I missing here?

Thanks!
