这篇文章主要介绍了Python实现快速多线程ping的方法,实例分析了Python多线程及ICMP数据包的发送技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了Python实现快速多线程 ping的方法。分享给大家供大家参考。具体如下：

									#!/usr/bin/python

									#_*_coding:utf-8_*_

									#

									'''

									名称：快速多线程ping程序

									开发：gyhong gyh9711

									日期：20:51 2011-04-25

									'''

									import pexpect

									import datetime

									from threading import Thread

									host=["192.168.1.1","192.168.1.123","192.168.2.1",

									"192.168.1.1","192.168.1.123","192.168.2.1",

									"192.168.1.1","192.168.1.123","192.168.2.1",

									"192.168.1.1","192.168.1.123","192.168.2.1",

									"192.168.1.1"]

									report_ok=[]

									report_error=[]

									class PING(Thread):

									  def __init__(self,ip):

									    Thread.__init__(self)

									    self.ip=ip

									  def run(self):

									    Curtime = datetime.datetime.now()  

									    #Scrtime = Curtime + datetime.timedelta(0,minute,0) 

									    #print("[%s]主机[%s]" % (Curtime,self.ip))

									    ping=pexpect.spawn("ping -c1 %s" % (self.ip))

									    check=ping.expect([pexpect.TIMEOUT,"1 packets transmitted, 1 received, 0% packet loss"],2)

									    if check == 0:

									      print("[%s] 超时 %s" % (Curtime,self.ip))

									    elif check == 1:

									      print ("[%s] %s 可达" % (Curtime,self.ip))

									    else:

									      print("[%s] 主机%s 不可达" % (Curtime,self.ip))

									#多线程同时执行

									T_thread=[]

									for i in host:

									  t=PING(i)

									  T_thread.append(t)

									for i in range(len(T_thread)):

									  T_thread[i].start()

									#

									#print ("\n=========问题主机情况如下==========\n")

									#output(report_error)

									#print ("\n=========正常主机情况如下==========\n")

									#output(report_ok)

执行结果：
