Select Files and Service

To start the service, Computer Management (right-click on My Computer, Manage) -> Services and Applications->Services->Mosquitto Broker->right click->Start

(You can also set the service to Automatic in right click on the service->Properties->Startup type)

If not run as a service, you can start it with
C:\”Program Files”\mosquitto\mosquitto.exe -v -c “C:\Program Files\mosquitto\mosquitto.conf”

To test, run:
C:\Program Files\mosquitto\mosquitto_sub -h localhost -v -t “TxNamib/#”

If the service is not running or accessible, the error wil show:
Error: No connection could be made because the target machine actively refused it.

Else, you will only see a message if it was “retained”, or you publish something to TxNamib now
C:\”Program Files”\mosquitto\mosquitto_pub -h localhost -t “TxNamib/servo.2003/03” -r -m “CLOSED”
C:\”Program Files”\mosquitto\mosquitto_pub -h localhost -t “TxNamib/servo.2003/03” -r -m “THROWN”
