Has anybody successfully run mosquitto on the openshift online version in a free account ? There are two SO questions relevant but not really solve all the questions: "How to connect to my MQTT Broker in Openshift" . It runs JBoss Fuse and needs either the SNI feature on the server or the port-forwarding on the client. "How can I access socket through Openshift" . The author mentions running mosquitto but there is no details as to how. Stuffs that have been done so far: I have run a python websocket server thus to have verified openshift does support websocket nicely though the DIY cartridge.

Is anyone has a logical explanation why despite I have the clear session flage = false I do not receive the updated published message I am subscribed to while i am not connected to the broker? With the aorementioned flag set to false I ran my App, And i kept publishing to a topic some values (from the PC to the broker not from the Android device to the broker). And then I unpluged the usb of the Android Device frm the pc, and kept publishing some values again. When I plugged the usb to the pc again, i expected to see the values I recently published to that topic, but I did not receive any. The

1.下载apache apollo apache-apollo-1.7.1-windows-istro.zip安装包，直接解压可使用 2.打开CMD命令窗口，管理员运行 3.进入到D:\apache-apollo-1.7.1\bin（解压之后的bin目录） 4.执行命令 apollo create myapollo D :/mybroker（ myapollo是broker实例名称，D:\mybroker是broker实例目录） 5.进入到mybroker\bin目录下，执行命令 　　apollo-broker run 6.将mybroker设置为windows服务： 执行命令 apollo-broker-service install 7.修改用户名密码 直接在\mybroker\etc 打开users.properties，将admin=password改为自己的用户名和密码 来源： https://www.cnblogs.com/aizj/p/11686458.html

Hi I have some code which includes publish/subscribe and actors. The generic_device class allows me to create other actors. I was wondering how do I create a specific actor from the generic_device class when I subscribe to a topic and if the topic isn't subscribed then no actor is created from the generic_device class. At the moment it is just if a specific message is received then the actor is created. All help appreciated thanks. import logging from datetime import timedelta import time from thespian.actors import * from transitions import Machine import paho.mqtt.client as mqtt class laser

I have a raspberry pi 3 with raspbian stretch as its operating system. I have installed and fully configured a MQTT broker on the raspberry pi following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-the-mosquitto-mqtt-messaging-broker-on-ubuntu-16-04 Everything works fine and well on the broker's side. The certificates get renewed after 60 days and you can only connect to port 1883 via the localhost and the other ports (8883 and 8083) are open but can only be accessed using TLS version 1.2 and for the latter also using websockets. Below you can find

I am trying to configure a Raspberry Pi (Raspbian, Jessie) to send temperature data from a DS18B20 sensor to my MQTT broker. I have installed mosquitto, mosquitto-clients, and python-mosquitto. I have also installed paho-mqtt. Mosquitto seems to be working fine; I can publish from the command line but I can not get ANY python script I've written or found to publish or subscribe. Why does this work from the command line, mosquitto_pub -h 192.168.0.21 -d -t test/test -m "Hello world!" while this script does not? #!/usr/bin/env python import paho.mqtt.client as mqtt # set up the mqtt client mqttc

Here is paho Async client: client = new MqttAsyncClient(appProps.getProperty("mqtt.broker"), appProps.getProperty("mqtt.clientId"), new MemoryPersistence()); client.setCallback(this); client.connect(null, new IMqttActionListener() { @Override public void onSuccess(IMqttToken imt) { try { client.subscribe(Constants.internalTopics, Constants.internalTopicQOS); } catch (MqttException ex) { ex.printStackTrace(); } } @Override public void onFailure(IMqttToken imt, Throwable thrwbl) { thrwbl.printStackTrace(); } }); Here I am sending messages in loop: while (iterator.hasNext()) { try { client
