Hardware Requirements
123 Flash Chat Server Software will be compatible with most server hardware.

The minimum hardware requirements are as follows:

1 GHz or faster processor
256 MB of RAM or more
100 MB free hard disk space or more
Dedicated Intel® Core™2 Duo Processor with 2048MB RAM is eligible to handle 1000 or more concurrent users.
Adding extra RAM and processors will improve the performance of 123 Flash Chat.

Java Virtual Machine(JVM) Requirements
A Java Virtual Machine (JVM), or a Java Developer Kit (JDK), fully compliant with the Sun J2SDK 5.0 is required to run the 123 Flash Chat server. We recommend J2SDK 5.0 or a higher version.

For the current version of JDK, visit http://java.sun.com/.

Note: The Windows and Linux versions of 123 Flash Chat Server Software now include Sun J2SDK 5.0 so it won't be necessary to install JDK again.

Port Requirements
123 Flash Chat Server Software needs at least ONE free port. The default port is: 51127

123 Flash Chat Server Software can listen to two ports simultaneously to guarantee the accessibility:
a low one (<1024) and a high one (1024~65535).

To ensure your users don't have to configure a firewall before accessing 123 Flash Chat, the low port can be set to 95 or 443, since it is allowed by most users' firewalls.

But remember, ports below 1024 can only be accessed using flash player 7 or 8. That's why you may set a high port (1024~65535) to serve lower version flash player.

123 Flash Chat Server Software has a built-in web server JUST for testing purpose. The default port value for this web server is 35555.

Note: In Linux, only root user can start the ports below 1024.
