Question:
Rush not working on my Orion Context Broker

Description:
I have deployed an Orion Context Broker v0.20.0 instance using AWS. I'm trying to show an entity from it on the MapViewer widget of the Fiware Lab Wirecloud Mashup.

It seems like I'm having some kind of trouble with the NGSI source operator. I have configured it with:

NGSI server URL: http://MyORionInstanceIP:1026
NGSI proxy URL: https://ngsiproxy.lab.fi-ware.org (I have also tried ngsiproxy.lab.fiware.org)

I run my Conntext broker instance like this: contextBroker -port 1026 -logDir /var/log/contextBroker -pidpath /var/run/contextBroker/contextBroker.pid -dbhost localhost -db orion -t 0-255 -rush localhost:5001, and it works, but when I accept the operator configuration to create the subscription, this is what I read on my Context Broker:

DEBUG@12:07:40 senderThread.cpp[47]: sending to: host='ngsiproxy.lab.fi-ware.org', port=443, verb=POST, tenant='', service-path: '', xauthToken: '', path='/callbacks/14:27:47-1:15:08:34-1', content-type: application/xml

I know there is a similar question here, but it hasn't solved my problem so far, neither the Orion documentation.

I really appreciate any help you can provide.

EDIT:

It looks like that rush wasn't event installed, so I did it.

But everytime I try to run the listener it gives me this error:

Now, when I accept the operator, this are the traces:

-ORION:

Any ideas, please?

EDIT 2:

I've manage to get it working thanks to the responses. The problem was that I was using redis 2.4, and it's required the 2.6 or supperior version. Now I can see my entities in the Map Viewer.

In case someone runs with the same problem, don't forget to install Rush and follow this instructions to install Redis 2.6:

Thank you all for your assistance.
