When i tried to run a python script( exists in the controller node ) remotely on an openstack instance using this command.

root@controller:~# ssh -i mykey.pem ubuntu@192.168.x.x python < /root/application/DockerProgramming.py

I received these errors:

Traceback (most recent call last):

File "<stdin>", line 22, in <module>

requests.exceptions.ConnectionError: ('Connection aborted.', error(13, 'Permission denied'))

Where is the problem and how can i solve it ?
