Requirements
============

- Twisted Core >= 2.0.0
- Twisted Words >= 0.4.0
- uuid.py (http://ofxsuite.berlios.de/uuid.py)
- A jabber server that supports the component protocol (JEP-0114)

For the PostgreSQL backend, the following is also required:

- PostgreSQL
- pyPgSQL

Installation
============

Run:

  python setup.py install

Configuration
=============

The configuration file is created using Twisted's mktap, which needs a number
of parameters:

 --jid: The Jabber ID the component will assume.
 --rport: the port number of the Jabber server to connect to
 --secret: the secret used to authenticate with the Jabber server.
 --backend: the backend storage facility to be used (memory or PostgreSQL).

The default settings of mktap for Idavoll use the memory database and assume
the default settings of jabberd 2.x for --rport and --secret.

jabberd 2.x
===========
You can use the 'legacy' component support that defaults to port 5347 with
secret 'secret'. You do not need to add anything specific for this service.

jabberd 1.4.x
=============

Put the following in the jabber.xml configuration file of jabberd:

  <service id='pubsub.localhost'>
    <accept>
      <ip>127.0.0.1</ip>
      <port>5347</port>
      <secret>secret</secret>
    </accept>
  </service>

and restart jabberd. Unlike jabber 2.x, you can only have one component per
port, so the port number may need to be changed.

For other server implementations, please refer to its documentation on
how to interact with server side components using the protocol defined in
JEP-0114.

Then, in the same directory as this file run:

  mktap idavoll --rport=5347 --jid=pubsub.localhost --secret=secret

This uses the (default) memory based backend.

For using the PostgreSQL backend, create a database (for example named pubsub)
like so:

  createdb pubsub
  psql pubsub <db/pubsub.sql

To use this backend, add the --backend=pgsql parameter to mktap.

For viewing all options, run:

  mktap idavoll --help

The generated file idavoll.tap now holds the configuration.

Running
=======

Using the configuration file idavoll.tap, run:

  twistd -of idavoll.tap

This will start the service and run it in the background. It generates a
file twistd.pid that holds the PID of the service and a log file twistd.log.
The twistd utility has a fair number of options that might be useful, and
can be viewed with:

  twistd --help
