Hardware Requirements

123 Web Messenger Chat 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 Web Messenger.


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 Web Messenger. 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 Web Messenger Chat Software now include Sun J2SDK 5.0, so it won't be necessary to install JDK again.

Port Requirements

123 Web Messenger Chat Software needs at least ONE free port. The default port is: 1558.

123 Web Messenger Chat Software can listen to two ports simultaneously to guarantee the accessibility:

A low one (<1025) and a high one (1025~65535)

To ensure your users not have to configure a firewall before accessing 123 Web Messenger, the low port can be set to 80 or 443, since it is allowed by most users' firewalls.

But remember, ports below 1025 can only be accessed using flash player 7 or 8. That's why you may set a high port (1025~65535) 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 1560.

Note: In Linux, only root user can start the ports below 1025.
