 Many people communicate on a day to day basis using tools like Google Hangouts, Skype, Whatsapp and what have you. What do most of these tools have in common? Well, though they're meant to communicate, they're only open as long as you communicate with other people who make use of the same proprietary solution, i.e. they don't support open standards like XMPP or SIP. Google used to support XMPP in Google Talk, however XMPP isn't supported anymore since they moved to the current Google Hangouts.

 After installation of the ejabberd server, several TCP-ports will be opened up on the server. It's advisable to only allow external traffic to and from the following ports (as long as you don't change the default values):
-==public==
-  * port 5222  # allow XMPP-client traffic
-  * port 5269  # allow XMPP-server traffic
-  * port 5275  # allow XMPP-filetransfer traffic
-  * port 7777  # allow file transfer via mod_proxy65 ([[http://xmpp.org/extensions/xep-0065.html|SOCKS5 bytestreams]])
+==allow for public==
+  * tcp/5222  # XMPP-client traffic

+  * tcp/7777  # XMPP-filetransfer traffic (via mod_proxy65 ([[http://xmpp.org/extensions/xep-0065.html|SOCKS5 bytestreams]])
-==admin==

-  * port 4369  # don't allow external access to epmd, though we need it locally for the ejabberdctl tool

 You can create and register a new user like so:
-  ejabberdctl register user1 jabber.example.com 'h1spassw00rd'
+  ejabberdctl register fred  jabber.example.com 'h1spassw00rd'

 There is also 'Web Admin', a small admin webinterface you can check out at:
-  http://example.com:5280/admin
+  http://jabber.example.com:5280/admin
 More information on 'Web Admin' is available at [[http://www.process-one.net/docs/ejabberd/guide_en.html#htoc75|http://www.process-one.net/docs/ejabberd/guide_en.html#htoc75]]
 However, we prefer the cli anyway :-)
+====video-bridge====
+For conferencing by using a central-server, with all clients connected to this in a star-topology, a bridge is available from jitsi. It is named 'video-bridge'.
+===installation===
+Get the software from https://download.jitsi.org/jitsi-videobridge/linux/
+Create a useraccount:
+  groupadd jitsi
+  useradd -d /opt/jitsi-videobridge-linux-x64 -s /bin/bash -g jitsi jitsi
+  chown -R jitsi.jitsi /opt/jitsi-videobridge-linux-x64
+Add an entry to /etc/hosts
+  ...
+.2.3.4 yourhostname.example.com yourhostname  jitsi-videobridge.jabber.example.com
+  ...
+Install software from the debian-repository:
+  apt-get install  unzip  default-jre-headless
+Install the video-bridge:
+  su - jitsi
+  unzip /tmp/jitsi-videobridge-linux-x64-65.zip
+  mv jitsi-videobridge-linux-x64-65/lib .
+  mv jitsi-videobridge-linux-x64-65/jvb.sh .
+  mv jitsi-videobridge-linux-x64-65/jitsi-videobridge.jar jitsi-videobridge-v65.jar
+Create a start-script /opt/jitsi-videobridge-linux-x64/start-bridge with content:
+  #!/bin/bash
+  HOME="/opt/jitsi-videobridge-linux-x64-63"
+  ${HOME}/jvb.sh --secret=VerySecretpw --domain='jabber.example.com' --host='localhost' --port=5275
+Set the properties:
+  chmod 700 start-bridge
+Now we have to make some additions/changes to the /etc/ejabberd/ejabberd.cfg
+Add a listener in the ejabberd Use the same port as mentioned above.
