win8.1怎么升级win10,紫藤家园spank,调教美少女

复制代码 代码如下:

# -*- coding: cp936 -*-
import socket
from threading import thread,activecount,lock
from time import ctime
mutex = lock()

class loop(thread):
    def __init__(self,ip,port,que):
        thread.__init__(self)
        self.ip     = ip
        self.port   = port
        self.que    = que

    def run(self):
        global mutex
        try:
            client = socket.socket()
            indicator = client.connect_ex((self.ip,self.port))
            if mutex.acquire(1):
                if indicator == 0:
                    que.append(self.ip+'\t'+str(self.port))
                else:
                    print self.ip,'\t',str(self.port),'不可达'
                mutex.release()
        except:
            if mutex.acquire(1):
                print self.ip,'\t',str(self.port),'不可达'
                mutex.release()

class main(thread):
    def __init__(self,ip,que):
        thread.__init__(self)
        self.ip  = ip
        self.que = que

    def run(self):
        i = 0
        while i < 65536:
            if activecount() <= 200:
                loop(ip=self.ip,port=i,que=self.que).start()
                i = i + 1

if __name__ == '__main__':
    que = []
    ip = raw_input('ip=')

    main = main(ip = ip,que = que)
    main.start()

    while true:
        if activecount() <= 1 and main.isalive() == false:
            break

    print ''
    f = open('portopen.py','a')
    f.write("'''")
    f.write(ctime()+'\n')
    f.flush()
    for i in range(0,len(que)):
        print que[i]
        f.write('\t'+que[i]+'\n')
        f.flush()
