TCP实现时间戳服务器和客户端

[python]代码库

#! /usr/bin/env python
#服务器（tsTserv.py）
from socket import *
from time import ctime
HOST = ''
PORT = 21567
BUFSIZ = 1024
ADDR = (HOST,PORT)
tcpSerSock = socket(AF_INET,SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(5)
while True:
    print 'Waiting for connection...'
    tcpCliSock,addr = tcpSerSock.accept()
    print '...connection from:',addr
    while True:
        data = tcpCliSock.recv(BUFSIZ)
        if not data:
            break
        tcpCliSock.send('[%s] %s' % (ctime(),data))
        #tcpCliSock.close()  不关掉会报错
tcpSerSock.close()
=====================================================
#! /usr/bin/env python
#客户端（tsTclnt.py）
from socket import *
