RPI mqtt gateway not working with user/password authentication

[piotrraczynski]

I'm unable to connect to mqtt server (based on mosquitto 1.5.7) with user/password authentication. Passwordless connection works fine. At the same time I'm able to connect to the same broker with mosquitto_sub client.

I checked development branch, 2.3.1 and 2.2.0 tags.

gateway config:

./configure --my-transport=rfm69 --my-rfm69-frequency=868 --my-is-rfm69hw --my-gateway=mqtt --my-controller-ip-address=192.168.1.45 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mosquitto --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18 --extra-cxxflags="-DMY_RFM69_NETWORKID=(100)" --my-mqtt-username=mosquitto --my-mqtt-password=123456

debug output:

Also tried 2.0.14 mosquitto from source. On that version, with some debugging logs I got (from the broker):

1648458618: New connection from 192.168.1.105:57522 on port 1883. 1648458618: Sending CONNACK to mosquitto (0, 5) 1648458618: Client mosquitto disconnected, not authorised. 1648458618: New connection from 192.168.1.105:57524 on port 1883. 1648458618: Sending CONNACK to mosquitto (0, 5) 1648458618: Client mosquitto disconnected, not authorised.

the password I provide is correct.

Is the password as simple as 123456, or does it contain any special characters that might become mangled by the shell or the configure script?

[piotrraczynski]

I was not able to get any password working. I started with more complicated one but then settled with 123456. I also printed username and password from mysgw itself as debug strings. They do not look mangled in any way.

Anyway, at least temporary I started to use mqtt with no password but actually setup my external gateways in zerotier network.

@piotrraczynski I think I found the problem. The parameter to ./configure is --my-mqtt-user, not --my-mqtt-username

[mfalkvidd]

The configure command actually outputs this when inputting my-mqtt-username:

[WARNING] Unknown option detected:--my-mqtt-username=mosquitto, ignored

But the warning is very easy to miss, I missed it myself.

[mfalkvidd]

@piotrraczynski have you had a chance to verify the suggested solution?

Closing due to inactivity and what (probably) was a configuration error. Feel free to reopen.
