Linux ejabberd

ejabberd is an open source platform built on Jabber/XMPP.

XMPP (Extensible Messaging and Presence Protocol)

Startup

To start, stop, status, restart

 # ejabberdctl start

Host - Updated the host to include my domain.

 {hosts, ["localhost", "johnfreier.com"]}.

Turned off the web admin interface

 %%web_admin

Turned off user registration. Switch 'allow' to 'deny'. You will need to register users before turning this off.

 {access, register, [{deny, all}]}.

TTLS - I needed to enable TTLS to be able to communicate between servers. To get this working correctly I also needed to uncomment out the pem cert.

 {s2s_use_starttls, true}.
  
 {s2s_certfile, "/etc/ejabberd/ejabberd.pem"}

This is how you register an account.

 # ejabberdctl register myuser johnfreier.com password
