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
1554356888: Config loaded from /etc/mosquitto/mosquitto.conf.

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

protocol mqtt
listener 9001 127.0.0.1
protocol websockets

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:

changing config to:

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'm in the middle of installing and configuring an XMPP server, using ejabberd on Windows server 2012, running on an EC2 box.
I have opened port 5222 within windows firewall, and added to the security group for the EC2 instance
Custom TCP Rule
TCP
5222
0.0.0.0/0
ejabberd_c2s
Custom TCP Rule
TCP
5222
::/0
ejabberd_c2s
My XMPP logins are not working, and so I've turned to telnet to try and debug - it sees that port 5222 is reporting as closed:
PS C:\WINDOWS\system32> telnet hostname.com 5222
Connecting To hostname.com...Could not open connection to the host, on port 5222: Connect failed
Any guidance or steps towards debugging would be appreciated!
The issue here was in ejabberd's default configuration of "::" as an IP to listen, which forced it to listen only to IPv6.
By updating the ejabbed config to
port: 5222
ip: "0.0.0.0"
module: ejabberd_c2s
I was able to connect via telnet, and able to access the server using XMPP.
I am running an Akka HTTP service on port 8080 in my EC2 instance. It expects web socket connections, but normal HTTP should return 400 bad request.
I use this code to start Akka service:
Http().bindAndHandle(route, "localhost", 8080)
From the remote terminal I have this expected behavior, but not from outside.
$ wget ec2-XX-XXX-XX-XXX.compute-1.amazonaws.com:8080
--2017-10-01 15:27:31-- http://ec2-XX-XXX-XX-XXX.compute-1.amazonaws.com:8080/
Resolving ec2-XX-XXX-XX-XXX.compute-1.amazonaws.com... XX.XXX.XX.XXX
Connecting to ec2-XX-XXX-XX-XXX.compute-1.amazonaws.com|XX.XXX.XX.XXX|:8080... failed: Connection refused.
Here is my inbound rules configuration:
If I do netstat --listen -p the port 8080 does not appear.
Thanks!
I found out the problem. I should be binding the service to the private IP address of the EC2 instance.
I have installed Mosquitto MQTT in one of the EC2 instance(ubuntu) and broker running fine with localhost.
I can able to publish/subscribe in the local machine and as well another EC2 instance (both EC2 in same subnet 172.31.X.X)
Now, i want to connect the broker from a PC outside for (publish/subscribe). So, i tried to configure the broker IP to EC2 instance public IP.
VirtualBox:cat /etc/mosquitto/mosquitto.conf
# Place your local configuration in /etc/mosquitto/conf.d/

# A full description of the configuration file is at

carun#carun-VirtualBox:~$
But, while restarting the broker am getting the above error "Cannot assign requested address"
Done so far,
Allowed (inboud/outbound) all access to EC2.
Disabled firewall in EC2
-Allowed all security level access to EC2 security group.
But no luck,
So question,
How to assign a EC2 Public IP to the broker?
How can I access MQTT broker out side of world?
Thanks in advance for your help!
Remove the ip address (50.24.39.66) from the end of listener line (or just remove the whole line) to allow mosquitto to bind to all available IP addresses
