MQTT keine Verbindung

[Limbi]

Hallo zusammen,

ich habe gerade OH 3.2 neu installiert und über die Konsole auch Mosquitto installiert.

Der Dienst scheint auch zu laufen. Passwort ist keines verwendet worden.

Per MQTT.fx kann ich nun aber keine Verbindung bekommen.

Ich sitze nun echt schon mehrere Stunden dran und finde keine Lösung....

Bin für jede Hilfe dankbar.

Hier noch die MQTT.fx Einstellungen:

Gerade herausgefunden das irgendetwas den Port 1883 bereits blockiert.
Habe das in einem anderen Thema schon mal gelesen. Da konnte aber keine Lösung gefunden werden.

Wie kann ich heraus finden wodurch der Port blockiert wird?

Es handelt sich um eine frische 3.2.0. Installation.

Wie kann ich heraus finden wodurch der Port blockiert wird?

sudo lsof -i -P -n | grep LISTEN

liefert alle Ports, auf denen gelauscht wird

Mmmmm. Anscheinend nur Mosquitto

[HiG]

Da ich letztens auch das mqtt.fx nicht zum laufen bekommen habe....bin ich auf die rudimentären Befehle ausgewichen.

Versuch doch einfach mal auf der Konsole

Code: Alles auswählen

mosquitto_sub -h 192.xxx.xxx.xxx  -t xxmqtt/kanal/#

und sende Dir mit

Code: Alles auswählen

mosquitto_pub -h 192.xxx.xxx.xxx   -t xxmqtt/kanal -m "test123"

ne Nachricht

Dann weisst Du zumindest das es funktionieren müsste. Ich nutzte die beiden mittlerweile nur noch

[peter-pan]

Schau mal in diesen Thread rein. Da wirst du sicher fündig. Vor allem wirst du am Anfang deiner "/etc/mosquitto/mosquitto.conf" noch diese Zeilen eintragen müssen:

Code: Alles auswählen

listener 1883
allow_anonymous true

Himmeldonnerkeil!!! Es funktioniert!!!!
Was mich nur wundert. Es kommt immer noch die Fehlermeldung dass der Port belegt ist:
