title: How to use client id in Mosquitto MQTT?
body: <p>I am new to Mosquitto. I have installed Mosquitto and Mosquitto Client in Ubuntu. I am trying to subscribe with client-id also publish with client-id, please look the command that I have run in console, but unfortunately, the subscriber is not receiving the message.</p>
  
  <p>Subscription
