========= server ==================

import socket

HOST = '127.0.01'                 # Symbolic name meaning the local host

PORT = 50007              # Arbitrary non-privileged port

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

s.bind((HOST, PORT))

s.listen(1)

conn, addr = s.accept()

print 'Connected by', addr

while 1:

    data = conn.recv(1024)

    if not data: break

    conn.send('server: ' + data)

conn.close()

========= client =====================

# Echo client program

import socket

HOST = '127.0.0.1'    # The remote host

PORT = 50007              # The same port as used by the server

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

s.connect((HOST, PORT))

while(1):

s.send('Hello, world')

data = s.recv(1024)

print 'Received', repr(data)

s.close()
