Mosquitto MQTT Broker

[Armin@netPI]

Well for a better view I recommend to all MQTT users to install the tool MQTT-Explorer http://mqtt-explorer.com/ under windows (instead of Node-RED).

This tool is for free and much better to explore a running MQTT broker since it monitors ALL topics at once.

As next I installed the same eclipse-mosquitto:latest as you did. I also mapped the ports 1883 and 9001 ... and guess what ... the MQTT broker is not reachable via MQTT Explorer. So there seems to be a general problem with the latest version

When you click on the container and watch the log file it says:

Code:

1614766138: mosquitto version 2.0.7 starting
1614766138: Config loaded from /mosquitto/config/mosquitto.conf.
1614766138: Starting in local only mode. Connections will only be possible from clients running on this machine.
1614766138: Create a configuration file which defines a listener to allow remote access.
1614766138: Opening ipv4 listen socket on port 1883.
1614766138: Opening ipv6 listen socket on port 1883.
1614766138: Error: Address not available
1614766138: mosquitto version 2.0.7 running

"Starting in local only mode .Connections will only be possible from clients running on this machine" ? I don't know what this means right now. Maybe this is the explanation why it does not reachable from remote machines. 

I think on the MQTT broker landing page https://hub.docker.com/_/eclipse-mosquit...escription you will find more about this "local" mode. At the moment I am clueless. Earlier version worked well and with no problems at all.

Thx
