LAN Messenger

A LAN messenger is an instant messaging program designed for use within a single local area network (LAN). There are advantages using a LAN messenger over a normal instant messenger. The LAN messenger runs inside a company or private LAN, and so an active Internet connection or a central server is not required (P2P). Only people who are inside the firewall will have access to the system. Communication data does not leave the LAN, and also the system can not be spammed from the outside (Darknet). Many LAN messenger offer basic functionality for sending private messages, file transfer, chatrooms and graphical smileys.
