Then we copied the sshx script from the ipython1 distro into /imaging/local/linux/bin
Then we did `touch .bashrc` to stop an sshx error message.
Then (for the sake of argument) we made a tiny script to test with:

{{{#!python
controller = dict(host='l42',
                  engine_port=None, # default is 10105
                  control_port=None,
                  )

# keys are hostnames, values are the number of engine on that host
engines = dict(l31=2,
               l32=2,
               l33=2,
               l34=2,
               )
}}}

Then we ran `ipcluster -f small_cluster.py`

and got this:

{{{
Starting controller:
Starting engines:   
Sarting 2 engines on l34
Sarting 2 engines on l32
Sarting 2 engines on l33
Sarting 2 engines on l31

Your cluster is up and running.

For interactive use, you can make a MultiEngineClient with:

from ipython1.kernel import client
mec = client.MultiEngineClient(('l42',10105))

You can then cleanly stop the cluster from IPython using:

mec.kill(controller=True)
}}}
