As already mentioned you should really create a new topic. It will increase your chances of getting a helpful answer.
But I'll give you a hint: you probably don't need the username and password. And did you want to publish or subscribe?
To subscribe:

Code: Select all

mosquitto_sub -d -t dev/test

This will only work if you're running it on the computer that runs the mosquitto daemon. If that's on a different computer you will have to use the -h parameter (https://mosquitto.org/man/mosquitto_sub-1.html)

Test this and if you have problems start a new topic describing in detail the problems you are seeing.
