Websockets - bind address/host in listener doesn't work for websockets protocol #3045

Open dchabrzyk opened 5 months ago

dchabrzyk commented 5 months ago

  1. Tested on RaspberryPi, Mosquitto version 2.0.11

  2. Application doesn't respect the bind address/host option for listener parameter when using websockets protocol. After changing protocol to MQTT everything works fine.

  3. Tested configuration entry listener 9001 127.0.0.1 protocol websockets

  4. netstat output masta@rpi-masta:/etc/mosquitto $ sudo netstat -tulnp | grep mosquitto tcp 0 0 127.0.0.1:1883 0.0.0.0: LISTEN 3583/mosquitto
    tcp6 0 0 :::9001 :::     LISTEN 3583/mosquitto

is that the whole configuration?

listener 9001 127.0.0.1
protocol websockets

running this tiny config in a container for 2.0.11 has the same issue. 2.0.12 does not. not sure if this is a libwebsockets or mosquitto issue, but you could try go up a few mosquitto versions too.

I'm facing a similar issue except that I am using 2.0.18.

config is: `allow_anonymous true listener 1883 protocol mqtt

listener 1884 protocol websockets`

netstat shows successful connections on 1883 but nothing even listening on 1884, even though the log during starting states
