How to run

1. first run the server

    ruby simple_server.rb
   

2. then run the client

    ruby simple_client.rb
   

simple_client.rb

require 'socket'      # Sockets are in standard library

hostname = 'localhost'
port = 2000

s = TCPSocket.open(host, port)

while line = s.gets   # Read lines from the socket
  puts line.chop      # And print with platform line terminator
end
s.close               # Close the socket when done

simple_server.rb

require 'socket'               # Get sockets from stdlib

server = TCPServer.open(2000)  # Socket to listen on port 2000
loop {                         # Servers run forever
  client = server.accept       # Wait for a client to connect
  client.puts(Time.now.ctime)  # Send the time to the client
  client.puts "Closing the connection. Bye!"
  client.close                 # Disconnect from the client
}
