XMPP
----
XMPP (eXtended Message and Presence Protocol, <http://xmpp.org/>) is the
instant-messenger protocol that drives Jabber and GTalk IM. You can
distribute messages via XMPP using the system below; however, you
need to run the XMPP incoming daemon to allow incoming messages as
well.
1. You may want to strongly consider setting up your own XMPP server.
Ejabberd, OpenFire, and JabberD are all Open Source servers.
Jabber, Inc. provides a high-performance commercial server.
2. You must register a Jabber ID (JID) with your new server. It helps
to choose a name like "update@example.com" or "notice" or something
similar. Alternately, your "update JID" can be registered on a
publicly-available XMPP service, like jabber.org or GTalk.
StatusNet will not register the JID with your chosen XMPP server;
you need to do this manually, with an XMPP client like Gajim,
Telepathy, or Pidgin.im.
3. Configure your site's XMPP variables, as described below in the
configuration section.
On a default installation, your site can broadcast messages using
XMPP. Users won't be able to post messages using XMPP unless you've
got the XMPP daemon running. See 'Queues and daemons' below for how
to set that up. Also, once you have a sizable number of users, sending
a lot of SMS, OStatus, and XMPP messages whenever someone posts a message
can really slow down your site; it may cause posting to timeout.
NOTE: stream_select(), a crucial function for network programming, is
broken on PHP 5.2.x less than 5.2.6 on amd64-based servers. We don't
work around this bug in StatusNet; current recommendation is to move
off of amd64 to another server.
Public feed
-----------
You can send *all* messages from your social networking site to a
third-party service using XMPP. This can be useful for providing
search, indexing, bridging, or other cool services.
To configure a downstream site to receive your public stream, add
their "JID" (Jabber ID) to your config.php as follows:
$config['xmpp']['public'][] = 'downstream@example.net';
(Don't miss those square brackets at the end.) Note that your XMPP
broadcasting must be configured as mentioned above. Although you can
send out messages at "Web time", high-volume sites should strongly
consider setting up queues and daemons.
Queues and daemons
------------------
......
The XMPP plugin allows users to send and receive notices over the
XMPP/Jabber/GTalk network.
XMPP (eXtended Message and Presence Protocol, <http://xmpp.org/>) is the
federating instant-messaging protocol of the future. It is wildly used
all over the world by organisations, private individuals and everyone.
GNU social allows you to receive and distribute messages via XMPP using
this plugin. To get it running, you must also use an active XMPP account.
Installation
============
add "addPlugin('xmpp',
array('setting'=>'value', 'setting2'=>'value2', ...);"
to the bottom of your config.php
Add an addPlugin call to your config.php with your settings. Please read
the "Pre-requisites" section of what is required for this to work.
Example
-------
The example account "update@site.example" is hosted on a machine which
can be reached at the hostname "xmpp.site.example".
addPlugin('Xmpp', array(
'user' => 'update',
'server' => 'site.example',
'host' => 'xmpp.site.example',
'password' => '...',
));
Pre-requisites
==============
0. You may want to strongly consider setting up your own XMPP server.
We highly recommend the XMPP server "Prosody" <https://prosody.im/>
because it is actively developed and highly secure and efficient. It
is of course also free software under the MIT license. The following
three pages will help you get it running, even self-hosted at home:
0.1 https://prosody.im/doc/dns
0.2 https://prosody.im/doc/install
0.3 https://prosody.im/doc/configure
1. You must register an XMPP user ID (JID) which is used to send and
receive messages. Call it something like "update@site.example" or
similar to hint at what the account is made for. You may register
the account on any public server (jabber.org, jit.si, etc...) if
you cannot run one yourself.
GNU social will not register anything for you, this must be done
manually, preferrably using an XMPP client like Swift, Empathy,
Jitsi or maybe even the commandline on your own server. With
prosody, that'd be (perhaps prepended with 'sudo'):
The daemon included with this plugin must be running. It will be
started by the plugin along with their other daemons when you run
scripts/startdaemons.sh. See the section "Queues and daemons" in
INSTALL for more about queuing and daemons.
prosodyctl adduser update@site.example
2. Configure your site's XMPP variables, as described below in the
Settings section below.
3. Learn to use the GNU social daemons for processing notice queues,
background checks and other processes which would be too slow to
perform on an active site. Using XMPP requires the "imdaemon" to
run, since a long-running XMPP connection is somewhat necessary.
Settings
========
user*: user part of the jid
server*: server part of the jid
resource (gnusocial): resource part of the jid
port (5222): port on which to connect to the server
encryption (true): use encryption on the connection
host (same as server): host to connect to. Usually, you won't set this.
debug (false): log extra debug info (e.g. sent/recv XMPP stanzas)
public: list of jid's that should get the public feed (firehose)
* required
default values are in (parenthesis)
Required
--------
user User part of the jid (like 'update')
server Host part of the jid (like 'site.example')
password The account's password. (your secret string)
Note that setting 'host' is required if the XMPP service is configured
with DNS SRV records, since XMPPHP does currently not support SRV
lookups.
Optional
--------
resource JID resource. Default: 'gnusocial'
encryption TLS server? Default: true
host Hostname for XMPP server? Default: same as server
port XMPP server port. Default: 5222
debug Log extra debug info. Default: false
public JIDs that should get the public feed (see "Public feed").
Since we do not currently support DNS SRV record lookup, please note
that you may have to enter an alternative 'host' parameter. This is
the case when update@site.example is not handled by the direct _address_
"site.example" but rather something like "xmpp.site.example".
Example
=======
addPlugin('xmpp', array(
'user'=>'update',
'resource'=>'social',
'server'=>'identi.ca',
'password'=>'...',
'public'=>array('bob@aol.com', 'sue@google.com')
));
Public feed
===========
You can send *all* messages from your social networking site to a
third-party service using XMPP. This can be useful for providing
search, indexing, bridging, or other cool services. Maybe a text
display next to your coffee machine at work.
To configure a downstream site to receive your public stream, add
their "JID" (Jabber ID) in the "public" array in your addPlugin call.
For example
addPlugin(array(
[...]
'public' => array('awesomebot@site.example'),
As the Pre-requisites section says, please only try to configure this
with daemons running properly in the background.
