Python实现快速多线程ping的方法
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:gyhonggyh9711 日期:20:512011-04-25 ''' importpexpect importdatetime fromthreadingimportThread 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=[] classPING(Thread): def__init__(self,ip): Thread.__init__(self) self.ip=ip defrun(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,"1packetstransmitted,1received,0%packetloss"],2) ifcheck==0: print("[%s]超时%s"%(Curtime,self.ip)) elifcheck==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=[] foriinhost: t=PING(i) T_thread.append(t) foriinrange(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:
administrator@nagios:/win/pexpect$./ping.py
