socket服务器端链接不上。。。

[加盾男爵]

书上有个例子，上面讲了如何用python的socket建立一个服务器端和客户端，然后相互通信的例子
我系统是ubuntukylin14.04,网通50Mb网络，所有防火墙全部关闭（我能关的都关了，但不排除有漏掉的选项）
服务器端代码 TCPServe.py

#/usr/bin/env python
import socket
import time
HostName = ""
HostCode = 65535
HostInfo = (HostName,HostCode)
Buffer = 1024
ST = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
ST.bind(HostInfo)
ST.listen(5)
while True:
    print "Waiting For Connection...."
    TCPHost,addr = ST.accept()                #connect
     print "...Connect From %s"%addr 

    while True:
        Datas = TCPHost.recv(Buffer)
        if Datas == None:
            break
        Datas = time.ctime() + Datas
        TCPHost.send(Datas)
        TCPHost.close()
ST.close()

然后我先运行了下这个脚本
结果是
Waiting For Connection....
然后就么有了。。。。我只能用ctrl+c强制关闭他，然后我看代码，我估计是accept()函数出了问题，所以我加了异常代码，想看看到底是什么情况，于是脚本变成了

#/usr/bin/env python
import socket
import time
HostName = ""
HostCode = 65535
HostInfo = (HostName,HostCode)
Buffer = 1024
ST = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
ST.bind(HostInfo)
ST.listen(5)
while True:
    print "Waiting For Connection...."
    try:
        TCPHost,addr = ST.accept()                #connect
    except Exception , e:
        print e
    else:  
        print "...Connect From %s"%addr 

    while True:
        Datas = TCPHost.recv(Buffer)
        if Datas == None:
            break
        Datas = time.ctime() + Datas
        TCPHost.send(Datas)
        TCPHost.close()
ST.close()

我本以为accept()出现问题会有些异常提示，方便问题排查，但运行脚本结果还是
Waiting For Connection....
没有其他任何信息。。。。
遇到这种情况怎么处理

再开一个窗口运行客户端： client.py

#!/usr/bin/python
# -*- coding: UTF-8 -*-
import socket
HOST='127.0.0.1'
PORT=65535
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.connect((HOST,PORT))
s.close()

我擦。。。。。我使用linux的&&命令的 python Serve.py && python Clint.py 貌似这样是不行的，，，，

先开一个窗口运行python serve.py 再开一个窗口运行python clint.py 另外，你的代码里还有一些错误 serve.py

#/usr/bin/env python
# -*- coding: UTF-8 -*-
import socket
import time
HostName = ""
HostCode = 65535
HostInfo = (HostName,HostCode)
Buffer = 1024
ST = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
ST.bind(HostInfo)
ST.listen(5)
while True:
    print "Waiting For Connection...."
    TCPHost,addr = ST.accept()  #accept是阻塞的，除非接收到client的请求，才会执行下一步, 否则一直阻塞
    print "...Connect From ", addr

    while True:
        Datas = TCPHost.recv(1024)
        if Datas == None:
            break
        Datas = time.ctime() + Datas
        TCPHost.send(Datas)
        # TCPHost.close()  # 关闭了还怎么接收。。。不能关闭
ST.close()

clint.py

#/usr/bin/env python
# -*- coding: UTF-8 -*-
import socket
HOST='127.0.0.1'
PORT=65535
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.connect((HOST,PORT))

print "connect success"

while 1:
    cmd=raw_input("Please input:")
    s.sendall(cmd)
    data=s.recv(1024)
    print "recv: ", data
s.close()   #关闭连接

[Halloween10]

TCPHost,addr = ST.accept() #connect 问题出在这一行
