Self signed SSL certificates for a fixed IP to use with Beremiz/Bananapi (PYRO)

[r_usso]

I have searched for this everywhere but was unable to find the answer.

I am using Beremiz (https://www.beremiz.org/). It uses PYRO to communicate between the server and client. The server is executed in a linux PC system and the client is executed in a Banana Pi. The client declares itself in the following address:

pi@bananapi:~/Beremiz/beremiz$ python Beremiz_service.py -i 192.168.2.6
WAMP import failed : No module named autobahn.twisted
Http interface port : 8009
Pyro port : 3000
Pyro object's uri : 
PYRO://192.168.2.6:3000/7f00010104be63eb2d0a9b6573161fc2
Current working directory : /home/pi/Beremiz/beremiz

The server connects to that address. Now I have to secure the connection so I have to use:

PYROS://192.168.2.6:3000

I have checked the source code of Beremiz and saw that it only checks "client.key" and "client.crt" for the ssl verification. I have created certificates and tried with common name "192.168.2.6" and "192.168.2.6:3000".

But whenever I try to connect using this certificates I get the following error from the server side:

PYRO connecting to URI : PYROS://192.168.2.6:3000

Any help, suggestions, or link to answer is highly appreciated.
