NAME:        tcpServer0 
SYNOPSIS:    tcpServer0 
DESCRIPTION:    The program creates a tcp socket in the inet 
                domain, binds it to port 10111, listen and accept 
                a connection from tcpClient0, and receives any message
                arrived to the socket and prints it out
