No working window appaers after start.
I have successfully installed Mosquitto on a Raspberry Pi 3 B+ (Debian = stretch).
Here is the result on the Raspberry :
pi@raspberrypi:~ $ mosquitto -v 1559603778: mosquitto version 1.6.2 starting 1559603778: Using default config. 1559603778: Opening ipv4 listen socket on port 1883. 1559603778: Error: Address already in use pi@raspberrypi:~ $
Apparently runs the program but no working window appears on the screen.
What am I doing wrong?

Error: Address already in use
I do not use Mosquito, but maybe it is already running automatically after RPI starts?
Thank you for your efforts.
Apparently it doesn't matter that the port is already in use.
I can't find a forum for Mosquitto users either.

mosquitto -v #start in verbose mode
If your mosquito is already running, you cannot start it again.
First stop it:
sudo service mosquitto stop sudo systemctl stop mosquitto.service
And then try your:
I do what you says and this what happen not more.
pi@raspberrypi:~ $ sudo service mosquitto stop
pi@raspberrypi:~ $ sudo systemctl stop mosquitto.service
pi@raspberrypi:~ $ mosquitto -v

@mslv129jdg How do you have installed mosquitto? if you have installed it with the standard
sudo apt install mosquitto mosquitto-clients
then, the server starts automatically when you boot your Pi.
Mosquitto is a server program so it is normal that you don't see any new window. See this if you want to know how to test your MQTT server.
I just uninstall mosquitto... with sudo apt-get purge --remove mosquitto*
The first time i install with :
sudo wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
sudo apt-key add mosquitto-repo.gpg.key
sudo wget http://repo.mosquitto.org/debian/mosquitto-stretch.list
sudo apt-get update
sudo apt-get install mosquitto
I look and study your link.
Eureka...eureka... Mosquitto works....
Thanks to your contributions I have achieved what I wanted step by step.... for which I thank you.
Indeed Mosquitto has worked in the beginning but I am expecting an opening window.
Meanwhile, I have successfully send a message from the terminal window 1 to 2.
Thanks to all who have taken the trouble to look at my question and send me a possible solution.
See you later.
