[IPython-dev] IPython Parallel Ports

[Dave Hirschfeld]

In my ipcontroller-client.json file it appears that I've got 6 ports 
defined:

{
  "control": <PORT1>, 
  "task": <PORT2>, 
  "notification": <PORT3>, 
  "exec_key": "secret_code", 
  "task_scheme": "leastload", 
  "mux": <PORT4>, 
  "iopub": <PORT5>, 
  "ssh": "", 
  "registration": <PORT6>, 
  "interface": "tcp://ipaddress", 
  "pack": "json", 
  "unpack": "json", 
  "location": "ipaddress"
}

The controller is running on the same grid as the engines but I need to 
communicate with it from outside i.e. without opening a remote desktop on 
the server to run my code.

I assume that some of these ports are only used for talking to the engines 
and aren't required to be open to the outside world? If so, which ports do I 
need to open so that I can talk to the controller from outside the closed 
grid network?

Thanks,
Dave

ipython-user. Apologies if this turns up twice.
