MQTT Gateway

[tiana]

I try to make raspberry pi 3 to work like a mqtt gateway according to this tutorial, but something is wrong.
https://www.mysensors.org/build/raspberry

1.How to check condition on the gateway working,not working, what sending, what receiving?

2.how to st my openhab to work with this gateway, i type this before "sudo make install"

./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1

and what port should set on my opehnab config?

I successful tested my gateway, the gateway receives commands from nodes, but something missing the OpenHAB not receive commands from the gateway i install mosquitto but missing a lot of information:
How to configure openhab to connect to the mosquitto ?

in openhab.cfg i put this

mqtt:mysensor.url=tcp://localhost:1883
mqtt:mysensor.clientId=MyMQTT
and other option is commented

my binding is

{mqtt="<[mysensor:MyMQTT/21/1/V_TEMP:state:default]"}

What this "MyMQTT means is this related to some setting in mosquitto?
