Janus - SPDY Privacy Proxy

Requirements

• Node.js v10.0

Installation

Janus is not published on NPM, so you need to get the code first.

git clone https://github.com/mozilla/node-janus

Next, use NPM to install all the dependencies.

cd node-janus  
npm install

Configuration and Usage

Janus

You can find the default Janus configuration in config/default.yml. All settings are exposed and documented there.

You may edit the settings directly in the default configuration file or preferably override some of settings using a custom configuration file, see the node-config documentation for more details about the configuration system.

To start the proxy, just run

./janus

The only command-line arguments supported are -h for help and -v for showing the version.

Firefox

You need Firefox Nightly for SPDY proxy support. When using self-signed certificates, you need to add it to Firefox first. To do this, use Firefox to call the proxy via its host-port combination.

https://<proxy-host>:<proxy-port>/

This should prompt you to add an exception for the self-signed certificate.

Desktop

Now, you can configure the secure proxy in Preferences/Advanced/Network/Settings. Select Automatic proxy configuration URL and set it to your custom PAC file or use the default configuration served by Janus.

http://<janus-host>:<pac-server-port>

This will serve a suitable PAC file with the proper host and ports set.

Android

For Fennec the steps are similar. Open about:config and set network.proxy.autoconfig_url to the location of your PAC file or the Janus PAC server. To load the PAC file and activate the proxy, set network.proxy.type to 2.
