The overall use of C / S framework, the main server -side and client into two parts , set ip and port number , and Linux, compile and debug procedures to achieve client and server connections each client side , and then as the server -side following transfer to achieve communication between client end . Since only one server -side , and you can have multiple client end , so the server side using a single list to manage multiple client side information , client side encapsulated for transmission of information sent through the body in the socket structure . This design uses the TCP / IP protocol ,so you can ensure reliable connection, but also preclude the use of project management in a popular linux gcc and makefile to compile, compile and debug greatly improved efficiency , improve the efficiency of the completion of the project, but due to simulate multiple client end Therefore, in the operating environment need to install a virtual system on the PC to operate multiple client side . The chat tool designed for full-duplex communication using communication , to achieve the five main functions: to-peer chat between new user registration and login, user , group ch
