Websockets Listener on Windows permanently bound to localhost - V1.5.3

[firegood]

Hello,

I just did a fresh install on a Windows server 2016 box and I am having an issue with the websockets functionality. I did install openSSL Light (x64) per the readme - and I also installed Visual studio 2013 redist (x64)

My config is default, with the following additions:

port 1883
protocol mqtt
listener 1884
protocol websockets

The program starts and shows that it is listening:

c:\Program Files\mosquitto>mosquitto.exe -v -c mosquitto.conf
1540920694: mosquitto version 1.5.3 starting
1540920694: Config loaded from mosquitto.conf.
1540920694: Opening websockets listen socket on port 1884.
1540920694: Opening ipv4 listen socket on port 1883.

Netstat -a shows that 1883 is listening on all ip addresses, but 1884 is only listening on localhost. This is confirmed by my web application that is only able to connect to port 1884 via localhost.

Proto Local Address Foreign Address State
TCP 0.0.0.0:1883 HOME:0 LISTENING
TCP [::]:1883 HOME:0 LISTENING
TCP [::]:1884 HOME:0 LISTENING

I also tried the following in my mosquitto config:

bind_address 192.168.10.10
port 1883
protocol mqtt

listener 1884 192.168.10.10
protocol websockets

But that dosent seem to work

Proto Local Address Foreign Address State
TCP 192.168.10.10:1883 HOME:0 LISTENING
TCP [::]:1884 HOME:0 LISTENING

I have encountered this problem, but I don't know how to solve it.

you can run the program like the following in the command line，try Netstat -a again
mosquitto -p 1884

the port 1884 will be opened, but my client couldn't connect to the broker~

This seems like a duplicate to #1004

[ralight]

I don't think it is necessarily a duplicate. This is Windows, 1004 isn't. 1004 is using libwebsockets 3.0.0, we have 2.4.2 on Windows. It might be that they are a duplicate after all, but for the moment I'd prefer to keep this open and separate.

[ralight]

In particular, Windows is not supported by the libwebsockets author, he relies entirely on contributions which means there is a reasonable amount of difference in behaviour between Windows/other systems.

i have the same issue, i just able to make conection over the websokects this way:
---------------------- Js------------------------------
var reconnectTimeout = 2000;
var host = "localhost";
var port = 9001;

var mqtt = new Paho.Client(host,port, "Clientjs");

if i use as host the ip address (192.168.1.101) or (127.0.0.1), it doesn't connect
i am not a native speaker english so forgive me for my mistake

Could you please try with this file?

https://mosquitto.org/files/binary/win32/mosquitto-1.5.3a-install-windows-x64.exe

It seems as though if libwebsockets is compiled with IPv6 support then it binds to localhost. That installer has no mosquitto changes, but has a libwebsockets without IPv6 support. It works for me.

[joseguatume]

there is this file but for windows x86 ?

[realgsg]

@ralight thank you so much! file mosquitto-1.5.3a, it works for me! can you share the version for windows x86 please?

[ralight]

There is now 1.5.4 available with both x86 and x64.

[joseguatume]

i still have the same issue, i cant change the ip address of websockets

[realgsg]

I have updated the version 1.5.4 x86, but I still have the same problem.

[satsdeva]

updated the version to 1. 5.4..

Config file:

port 8883
protocol mqtt
cafile C:\Program Files (x86)\mosquitto\certs\ca.crt
keyfile C:\Program Files (x86)\mosquitto\certs\server.key
certfile C:\Program Files (x86)\mosquitto\certs\server.crt
require_certificate false
tls_version tlsv1

listener 9883
protocol websockets
cafile C:\Program Files (x86)\mosquitto\certs\ca.crt
keyfile C:\Program Files (x86)\mosquitto\certs\server.key
certfile C:\Program Files (x86)\mosquitto\certs\server.crt
require_certificate false
tls_version tlsv1

log_type all
websockets_log_level 255

Getting below error :

I believe this should work on the upcoming 1.5.5 if you use:

socket_domain ipv4

in your config file.
