I am new to MQTT. I am trying to setup MQTT between 2 ubuntu 18.x hosts installed in vmware. Both of these hosts has id address and I can even ping or ssh each other successfully.
Now in first Ubuntu host (machine 1 which i am going to use as publisher) i have installed mosquitto and mosquitto-clients and i see mosquitto running (command ps -e) and same installation is done on second ubuntu machine 2 (which i am going to use subscriber).
Now when i use below commands , i dont see message in the subscriber host.
Machine2 > mosquitto_sub -h <Machine 1 IPaddress> -t test
Machine1> mosquitto_pub -h <Machine 2 IPaddress> -t test -m "first message"
Nothing shows up in subscriber machine 2.
I also used -d switch on publisher machine to see if any clue but didnt get any info.
Any help to solve this problem will be of great help
