• C code for a simple client (client.c) and server (server.c) that uses streaming sockets to send a message from client to server. The code is from this socket tutorial, which discusses the individual commands/steps.
  
• Compiling:
  
• The programs should compile "as is" on Linux:
  
• cc -o client client.c
  
• cc -o server server.c
• On Sun machines (running Solaris) you need to explicitly link the socket and nls libraries:
• cc -o client client.c -lsocket -lnsl
• cc -o server server.c -lsocket
• Execution:
• The command-line interface for the server expects a port number the server will be listening on (./server <port>)
• The client expects a machine name and the listening port (./client <host> <port>).
