Launcher

Though there need several socket operations to establish a connection over TCP/IP, servers do not have any functionality for connection establishment. An application called launcher is provided to start servers and to establish connections as follows.

  1. A launcher is invoked from a client. When the launcher is invoked, the client informs the launcher of a port number for TCP/IP connection and the name of a server.
  2. The launcher and the client establish a connection with the specified port number. One time password may be used to prevent launcher spoofing.
  3. The launcher creates a process and establishes a connection to the client. Then the launcher arranges for the newly created descriptors to be 3 and 4, and executes the specified server.

After finishing the above task as a launcher, the launcher process acts as a control server and controls the server process created by itself.
