This page is a proposal for a unified chat (instant messaging) environment.
Ticket: http://jira.bluelightav.org/browse/BLUE-1038
This is work in progress!!!
XMPP seem to be an acceptable choice:
- free protocol
- free accounts with jabber.org
- vast choice of clients
- inter-compatibility with gtalk and possibly other common services
Problems:
- Google Hangout does not support XMPP
Proposition:
- anyone should have either:
- Google account (including the users in the auroville.in.org domain) without Google Hangout activated
- a jabber.org account
- client: any choice within (Adium, Chat.app, Pidgin, Android Gtalk, etc). See also http://xmpp.org/xmpp-software/clients/
Jabber server
Few notes on the installation of a ejabberd server.
Note that there are many open and free jabber servers around, so we might not want to set up one.
Server setup in Debian
Below, the steps to configure on Rose:
apt-get install ejabberd
dpkg-reconfigure -plow ejabberd
Parameters for dpkg-reconfigure:
Jabber host name: rose
Administrator user name: admin
Administrator password: bluelightav
Web admin
User: admin , password: as set during dpkg-reconfigure
Security
- A self-signed certificate is created by debconf
- Admin user is created by default, with admin privileges
- By default, registration of new users can be done only with the web admin interface, not using a Jabber client. To allow users to register in-bound:
- Edit /etc/ejabberd/ejabberd.cfg
- Change at around line 496: {access, register, [{deny, all}]}.
- by: {access, register, [{allow, all}]}
service ejabberd restart
Iptables
A rule is added in the host node in order to forward all the incoming traffic to the jabber server:
-A PREROUTING -d 176.9.70.139/32 -p tcp -m tcp --dport 5222 -j DNAT --to-destination 192.168.42.107:5222
Clients
Psi
Protocol well supported, but a bit rough interface
Gajim
Good
