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:
administrator@nagios:/win/pexpect$ ./ping.py
