Elastix includes an Instant Messenger server called OpenFire. While not enabled by default it is very easy to enable.
What’s not so obvious is how to disable OpenFire if you decide, once you’ve had a look at it, you don’t want/need to run it. You might want to do this as OpenFire runs on Java which can be quite memory hungry, also it opens another point of attack to your server.
The easiest way to disable it is via the command prompt by running –
chkconfig openfire off
This will also stop it starting automatically when the server is rebooted.
