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.

||||

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.
|
||||
|
||||
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.
|
||||
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'):
|
||||
|
||||
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.
