So I am currently trying to get an MQTT client up and running to run TCP/IP, SSL and TLS-PSK with mosquitto on an intel galileo gen 2 board. I have been following this tutorial (https://www.codeproject.com/Articles/993790/Using-Edison-Securely-connect-IoT-Sensor-to-the-In) administered by Intel. What I am unsure about is how to implement the configuration directives as shown in the attached picture. Must I create a new .conf file or edit an existing one? Or has it got nothing to do with configuration files? Just not sure what to do or how to implement them. Any help on the subject would be appreciated.
