i'm running docker-compose.yaml with the configuration for mosquitto:
mosquitto:
image: eclipse-mosquitto
ports:
- 1883:1883
- 9001:9001
volumes:
- ./configuration/mosquitto:/mosquitto/config/
- ./configuration/mosquitto/logs:/var/log/mosquitto
I can see the following log when I run docker-compose:
1653666208: mosquitto version 2.0.14 starting
1653666208: Config loaded from /mosquitto/config/mosquitto.conf.

1653666208: Opening ipv6 listen socket on port 1883.
1653666208: Opening websockets listen socket on port 9001.
I can access the TCP on 1883, But I can't see the WebSocket service running on the server.
I tried the
sudo netstat -lnp| grep 9001
and it didn't return me anything.
What am I missing in the configuration?

I've read all the threads with similar questions, but couldn't find an answer.
Mosquitto config:

I've tried many things but nothing helped:
Trying websockets only
Trying another port (1883 and 9001 instead of 8080)
Switching off Windows firewall
If I change the config file to:
#listener 1884 127.0.0.1
#protocol mqtt
#listener 1883 127.0.0.1
protocol websockets
Mosquitto listens for websockets on port 1883 but logfile reads:

Gives me a logfile that says:

Tried another websockets client (https://www.eclipse.org/paho/clients/js/utility/) --> Failed to connect: AMQJSC0001E Connect timed out.
I can't get websockets to work with any configuration / port...
Can anyone confirm that Websockets in Mosquitto (32bit version 1.6.2 or 1.6.4) for Win10 are working ?
Your first config file won't work because you have both native MQTT and Websockets both trying to listen on port 1883. (this is because the default listener starts on port 1883), Not 100% sure how this is possible unless it's some strange IPv6 thing on Windows.
The second, is just changing the default listener protocol to Websockets, which in theory should work, assuming you try and connect to port 1883 from the webpage.
The third one makes the default listener on port 1883 Websockets and native on 8080. Again should work assuming you are trying to connect to 1883
The simplest config to enable Websockets should look like this:
listener 9001 127.0.0.1
protocol websockets
This will leave the native default listener alone on port 1883 (listening on all interfaces, use bind_address 127.0.0.1 before the listener line to make it only listen on localhost) and start the Websocket listener on port 9001
This turned out to be quite the challenge.
First I tried to get things working using an online broker and client. Still not working. I then switched to another computer and everything was working fine.
Switching back to the original computer I decided to test if websockets where working at all by going to https://www.websocket.org/echo.html
From that moment on everything started to work. First the online broker and client and then also the local server and clients. I have no idea why...
I'm trying to connect/publish from broker to web, but it's not work.
I am already searching on the internet, but cannot find anything to solve it.
example when someone told me to untag bridge_protocol on mosquitto.conf , it's not work but get another error.
my mosquitto version is 1.4.9
I think something need to change on mosquitto.conf
When I try mosquitto -v -c mosquitto.conf
the result is :
mosquitto version 1.4.9
config loaded from mosquitto.conf
opening ipv4 and 6 socket on port 8883
new connection from :11 on port 8883.
socket error on client <unknown>, disconecting.
I can connect/publish from Broker to web.
I'm going to make a guess here...
It looks from the log that you have just changed the default port mosquitto is listening on from 1883 to 8883 most likely with the port configuration option.
You are then trying to connect to this from a webpage using the Paho JavaScript client.
This is failing because while you have changed the port you have not told mosquitto that it needs to use the websocket protocol for that port. This is because the Paho JavaScript client can only use MQTT over WebSockets not native MQTT.
The way to fix this is to reset the default port back to 1883 and then add a listener on port 8883 specifically set up to use WebSockets.
e.g. a mosquitto.conf like this:
port 1883
listener 8883
protocol websockets
I have a mosquitto broker run on a linux behind my company proxy.
I have been configured a bridge to AWS same following: (mosquitto.conf)
connection bridge
address ec2-xxx-xxx-xxx-xxx.ap-northeast-1.compute.amazonaws.com:8089
remote_username admin
remote_password password
topic abc/raspi01 both 0
bridge_cafile /etc/pki/tls/certs/nginx-selfsigned.crt
bridge_insecure false
But when I start mosquitto service with command:
service mosquitto restart
In log file, There are some errors:
1554356888: mosquitto version 1.5.5 starting

I things the cause is my company proxy.
I have tried with settings in mosquitto.service, but it not resolve.

Can any body help me? Thank so much.
You can not use a HTTP proxy for MQTT bridge connection (or any native MQTT connection). MQTT is a totally different protocol.
Only MQTT over Websockets would work via a HTTP proxy, but you can not configure mosquitto to run a bridge with MQTT over Websockets.
If one uses HTTP CONNECT before sending connect
in net_mosq.c
rc = connect(*sock, rp->ai_addr, rp->ai_addrlen);
One can accomplish this.
HTTP CONNECT is protocol agnostic, it works on underlying TCP protocol.
I'm using Thorntail 2.3.0.Final, in documentation "5.4.2. Sockets" there is an example of configuring some kind of something:
thorntail:
network:
socket-binding-groups:
standard-sockets:
http:
port: 8081
I thought it starts listening on port 8081, but it persistently continues start listening port 8080
so how to configure port binding properly?
The shortcut way is to use:
thorntail:
http:
port: 8081
I've set up a mosquitto broker but it refuses to connect over websockets
here is my conf file:
# Place your local configuration in /etc/mosquitto/conf.d/
#
# A full description of the configuration file is at
# /usr/share/doc/mosquitto/examples/mosquitto.conf.example
pid_file /var/run/mosquitto.pid
persistence true
persistence_location /var/lib/mosquitto/
log_dest file /var/log/mosquitto/mosquitto.log
include_dir /etc/mosquitto/conf.d
listener 1883 0.0.0.0
listener 8008 0.0.0.0
protocol websockets
and I don't have any conf at conf.d
Using the PAHO javascript client I get a ERR_CONNECTION_REFUSED
by the way I'm using debian jessie as OS
-------------------------------------EDIT 1----------------------------------
I've lowered the iptables and it still not working.
The usual way to connect is working (with port 1883)
Here is the output when I start mosquitto
1477788244: mosquitto version 1.4.10 (build date Thu, 25 Aug 2016 10:12:09 +0100) starting
1477788244: Using default config.
1477788244: Opening ipv4 listen socket on port 1883.
1477788244: Opening ipv6 listen socket on port 1883.
The important line in the startup output is here:
1477788244: Using default config.
This says that mosquitto is using it's built in config (only listen on 1883 for native MQTT traffic) and not even reading your config file.
If you just start mosquitto with no command line options this is what is uses, it will not look for a config file in /etc/mosquitto/.
You need to explicitly tell mosquitto where it's config file with the -c option.
mosquitto -c /etc/mosquitto/mosquitto.conf
Depending on how you installed mosquitto you may need to edit the scripts that automatically start it on boot. This is probably in here: /etc/init.d/mosquitto
