Exercises

  • Develop a concurrent TCP server that generates random numbers in a predefined range.
  • Develop a concurrent TCP server that generates random numbers in a range that is given by the TCP client. This can be used as a way of randomly picking values from a set.
  • Add UNIX signal processing to the concurrent TCP server developed in this chapter to gracefully stop the server process when a given signal is received.
  • Develop a UNIX domain socket server that generates random numbers. After that, program a client for that server.
  • Develop a WebSocket server that creates a variable number of random integers that are sent to the client. The number of random integers is specified by the client at the initial client message.
