Installation and configuration guide
====================================

I assume that you have a basic understanding of XMPP and the the concept
of a XMPP component/transport. If not, please get a book about Jabber
or read the standards.

transWhat is a XMPP transport. By this means it extends the
functionallity of an existing XMPP server. It acts as a gateway between
the XMPP and WhatsApp networks. It receives WhatsApp messages and
forwards them to your XMPP client (and vice-versa).

The implementation of transWhat is based on the `Spectrum 2`_ framework
and the `Yowsup 2`_ library to interface with WhatsApp.

The following chart summarizes the involved components and the protocols
they use to communicate.

Prosody
-------

Installation
~~~~~~~~~~~~

I will not cover the installation of Prosody in this guide. Please look
for some other tutorials on how to do that.

Configuration
~~~~~~~~~~~~~

The only important thing for us is the configuration of a XMPP component
(Spectrum 2 in our case). See http://prosody.im/doc/components.

Append the following at the end of ``/etc/prosody/conf.d/transwhat.cfg.lua``

::

    Component "whatsapp.0l.de"
        component_secret = "whatsappsucks"
        component_ports = { 5221 }
        component_interface = "127.0.0.1"

Spectrum 2
----------

Installation
~~~~~~~~~~~~

Manual compile latest version from `Github`_. You can use the following
guide:
http://spectrum.im/documentation/installation/from\_source\_code.html.

Configuration
~~~~~~~~~~~~~

Create a new file ``/etc/spectrum2/transports/transwhat.cfg`` with the
following content:

::

    [service]
    user = spectrum
    group = spectrum

    jid = whatsapp.0l.de

    server = localhost
    password = whatsappsucks
    port = 5221

    backend_host = localhost
    backend = /usr/bin/transwhat

    users_per_backend = 10
    more_resources = 1

    admin_jid = your@jid.example

    [identity]
    name = transWhat
    type = xmpp
    category = gateway

    [logging]
    config = /etc/spectrum2/logging.cfg
    backend_config = /etc/spectrum2/backend-logging.cfg

    [database]
    type = sqlite3

transWhat
