Are there any plans to make PAHO proxy aware so that MQTT messages can cross an enterprise firewall to brokers hosted in the internet?
Thanks, Walt

Hi Walt,

we don't have plans for that right now. But I was just wondering this morning what other requirements there might be.

I don't have a good understanding of what making a client library "proxy aware" would entail. Can you expand?

Do you have an interest in a particular client (Java, C/C++, Python Javascript)?

Ian

Hi Ian,
I'm interested to have this capability in the java client and like to configure the proxy details (e.g. SOCKS4/5, HTTP, and port) when defining a client connection.

For illustration purpose see for example how this is solved with the SMACK XMPP client:

www.igniterealtime.org/builds/smack/docs/latest/javadoc/org/jivesoftware/smack/proxy/ProxyInfo.html

Thanks,
Walt

Does the use of an HTTP proxy imply WebSockets?

This document: http://docs.oracle.com/javase/7/docs/technotes/guides/net/proxies.html
says that you should be able to set a socks proxy with system properties (see section 2.4).

I realize that this is a setting for the whole JVM, so I'll add a feature request to our plans.

Hi Ian,
i want to know how to add and where to add proxy settings in paho-mqtt.

I guess my organization's proxy settings are blocking the request, so please guide me so that MQTT messages can cross an enterprise firewall to broker on internet.

Hi Saurabh,

If you have a socks proxy then you could follow the link posted in this answer: http://stackoverflow.com/questions/27834468/how-to-add-proxy-settings-in-paho-mqtt

If you have an http proxy then you've almost certainly got no hope, unless your proxy supports websockets and you configure your broker to support it. The Paho Python client won't work with websockets though.

Regards,

Roger

I'm interested in this, is there any development since 2013? specifically using a SOCKS5 proxy.

links to documentation?
links to issue/feature requests?

Hi,
I had the same problem; I wanted to connect with the Java MQTT Paho version to a public MQTT Broker through a Socks5 Proxy.

I solved the problem by using the following SocketFactory: https://github.com/greenaddress/GreenBits/blob/master/app/src/main/java/com/greenaddress/greenbits/spv/Socks5SocketFactory.java

Here is a example code snippet for using Socks5 Proxy with MQTT Paho:
String brokerUrl = "iot.eclipse.org"
String proxyHost = "localhost";
String proxyPort = "1080";
MqttClient mqttClient = new MqttClient(brokerUrl, MqttClient.generateClientId());
MqttConnectOptions conOptions = new MqttConnectOptions();
Socks5SocketFactory factory = new Socks5SocketFactory(proxyHost, proxyPort);
conOptions.setSocketFactory(factory);
this.mqttClient.connect(conOptions);


Might not be the most beautiful solution but worked for me. Smile
