2. Subscribe a mqtt client: (update url/ip for host, taken from last step, localhost in case of port forward)

   Code Block
   language bash
   mqtt subscribe -h $mqttHost20.113.42.183 -p $mqttPort1883 -t '#' -q 1 -u mqtt-user-1 -pw mqtt-password-1

   Do not close this terminal session. This will allow you to see the results.

3. From a different terminal session, publish a message to the topic “test”: (update url/ip for host, taken from last step, localhost in case of port forward)

   Code Block
   language bash
   mqtt publish -h $mqttHost20.113.42.183 -p $mqttPort1883 -t topic-1 -m Hello -q 1 -u mqtt-user-2 -pw mqtt-password-2

4. If everything is correct, the subscriber will receive the message:

   Code Block
   language bash
   mqtt subscribe -h $mqttHost -p $mqttPort -t '#' -q 1 -u mqtt-user-1 -pw mqtt-password-1

   Code Block
   language bash
