Jabber - Jabber gateways

ICQ Gateway

The best solution is PyICQ-t, other solutions are discussed on opennet.ru and kaktyc . I created binary RPMs of latest PyICQ-t for CentOS 5, so on this OS you just [[soho/prerequisites#Packaging|attach to my and dependent repositories] and install as follows:

yum install pyicq-t

You may need to rebuild source RPMs for other RedHat-based distributions.

Configure eJabberd. Edit /etc/ejabberd/ejabberd.cfg, add the following service record for ICQ transport 

{listen, [
  ...
   {5247, ejabberd_service, [
       {access, all},
       {hosts, ["icq.ourdom.com"], [{password, "somepassword"}]}
       ]}

Configure PyICQ-t. Copy default configuration file

Edit /etc/pyicq-t/config.xml and set a few parameters 

<jid>icq.ourdom.com</jid>
<mainServerJID>ourdom.com</mainServerJID>
<website>http://jabber.ourdom.com/</website>
<port>5247</port>
<secret>secretword</secret>
<encoding>windows-1251</encoding>

Restart both daemons

service ejabberd restart
service pyicq-t restart
chkconfig pyicq-t on

Open your Jabber client and register on ourdom.com. Perform service discovery and find ICQ transport. Add it to your roster, register with your ICQ UIN and password and open a connection. Your ICQ buddies will be automatically added to the roster.
