这篇文章主要介绍了Python基于多线程实现ping扫描功能,结合实例形式分析了Python多线程与进程相关模块调用操作技巧,需要的朋友可以参考下

本文实例讲述了Python基于多线程实现ping扫描功能。分享给大家供大家参考，具体如下：

									# -*- coding:utf-8 -*-

									#! python2

									import subprocess

									from Queue import Queue

									import threading

									class Pinger(object):

									  def __init__(self, ip_list, thread_num=2):

									    self._ip_list = ip_list

									    self._thread_num = thread_num

									    self._queue = Queue(len(ip_list))

									  def ping(self, thread_id):

									    while True:

									      if self._queue.empty():

									        break

									      addr = self._queue.get()

									      print 'Thread %s: Ping %s' % (thread_id, addr)

									      ret = subprocess.call('ping -c 1 %s' % (addr),

									                 shell=True,

									                 stdout=open("/dev/null", 'w'),

									                 stderr=subprocess.STDOUT)

									      if ret == 0:

									        print '%s: is still alive' % addr

									      else:

									        print '%s: did not respond ' % addr

									      self._queue.task_done() #unfinished tasks -= 1

									  def run(self):

									    for ip in self._ip_list:

									      self._queue.put(ip) #unfinished_tasks += 1

									    print '---------------------task begin------------------'

									    for i in range(self._thread_num):

									      thrd = threading.Thread(target=self.ping, args=(i + 1,))

									      #thrd.setDaemon(True)

									      thrd.start()

									    self._queue.join() # 主线程一直阻塞，一直等到Queue.unfiinshed_tasks == 0

									    print '---------------------task done-------------------'
