 Setting Up and Managing iChat Service

 

Opening Firewall Ports for iChat Service

iChat requires specific ports to be open on your server. If you have a firewall configured 
or you are using the Mac OS X Server firewall, you must enable these ports before you 
can use iChat.

Depending on the iChat functions you require, make sure the following ports are open.

If you run iChat service on a secure network behind a firewall, you don’t need to 
configure firewall settings as long as communication between users is within the 
network. Firewall settings are required when communicating outside the firewall.

For more information about the Firewall service and settings, see Network Services 
Administration.

Turning iChat Service On

Before you can configure iChat settings, you must turn the iChat service on in Server 
Admin.

Open Server Admin and connect to the server.

Click Settings, then click Services.

Select the iChat checkbox.

Click Save.

You can also start iChat service using the 

serveradmin

 command in Terminal. For more 

information, see Command-Line Administration.
