# Simple Server - Chapter 1 - server.py

import socket

host = ''                               # Bind to all interfaces

port = 51423

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)  #SO_REUSEADDR为可服用选项

s.bind((host, port))

s.listen(1)

print "Server is running on port %d; press Ctrl-C to terminate." \

      % port

while 1:

    clientsock, clientaddr = s.accept()

    clientfile = clientsock.makefile('rw', 0)

    clientfile.write("Welcome, " + str(clientaddr) + "\n")

    clientfile.write("Please enter a string: ")

    line = clientfile.readline().strip()

    clientfile.write("You entered %d characters.\n" % len(line))

    clientfile.close()

    clientsock.close()

客户端只要用telnet登录就可以:

$ telnet localhost 51423

Trying 127.0.0.1...

Connect to localhost
