在日常的工作中,我们通常会有去探测目标主机是否存活的应用场景,单个的服务器主机可以通过计算机自带的DOS命令来执行,但是业务的存在往往不是单个存在的,通常都是需要去探测C段的主机(同一个网段下的存活主机),这样使用DOS来进行操作是不可取,探测的速度太慢了,不满足实际需要。一般批量的操作需要使用脚本进行一键部署执行,本文主要通过使用Python语言来实现批量ping的操作(使用多线程实现Python批量处理)
Python版本 :Python3
使用的第三方库:subprocess, logging, threading, queue
日志导出模块功能:
def set_logging_format():
logging.basicConfig(level=logging.INFO,
format='%(message)s',
filename='ping_host.log',
filemode='w'
)
console = logging.StreamHandler()
console.setLevel(logging.INFO)
formatter = logging.Formatter('%(message)s')
console.setFormatter(formatter)
logging.getLogger('').addHandler(console)
多线程实现批量操作:
threads = []
THREAD_NUM = 20
user_iput = input('please input modren: ')
if user_iput == 'addr':
IP_L = IP_LIST
if user_iput == 'file':
IP_L = IP_QUEUE
for i in range (THREAD_NUM):
t = threading.Thread(target = ping_IP,args = (IP_L,))
threads.append(t)
for i in range (THREAD_NUM):
threads[i].start()
for i in range (THREAD_NUM):
threads[i].join()
完整代码部分:

import logging
import datetime
import time

# 实现日志导出
def set_logging_format():
logging.basicConfig(level=logging.INFO,
format='%(message)s',
filename='ping_host.log',
filemode='w'
)
console = logging.StreamHandler()
console.setLevel(logging.INFO)
formatter = logging.Formatter('%(message)s')
console.setFormatter(formatter)
logging.getLogger('').addHandler(console)
# 将需要ping 连接的IP加入队列
def insert_ip_queue(ip_list_path):
IP_QUEUE = Queue()
with open (ip_list_path,'r') as f:
for ip in f.readlines():
IP_QUEUE.put(ip)
f.close()
return IP_QUEUE
def IP_list ():
ip_list = Queue()
for i in range (1,255):
ip = '192.168.1.' + str(i)
ip_list.put(ip)
return ip_list
# print (IP_list())
#print (IP_list())
#定义 ping 函数
def ping_IP (IP_QUEUE):
while not IP_QUEUE.empty():
ip = IP_QUEUE.get().strip('\n')
#print (ip)
res = subprocess.call('ping -w 1000 -n 1 %s' % ip , stdout=subprocess.PIPE,shell=True)
#print (res)
if res == 0:
h =subprocess.getoutput('ping' + ' ' + ip)
#print (h)
if 'TTL=' in h:
res = ('网络可以正常连通平均延时 = %s' % h.split('平均 = ')[1])
else:
res = '网络连接失败!'
today = datetime.datetime.now().strftime("%Y - %m - %d %H : %M : %S")
logging.info("%s IP = %s %s" % (today,ip,res))
def main ():
set_logging_format()
ip_list_path = './hostip.txt'
IP_QUEUE = insert_ip_queue(ip_list_path)
IP_LIST = IP_list()
threads = []
THREAD_NUM = 20
user_iput = input('please input modren: ')
if user_iput == 'addr':
IP_L = IP_LIST
if user_iput == 'file':
IP_L = IP_QUEUE
for i in range (THREAD_NUM):
t = threading.Thread(target = ping_IP,args = (IP_L,))
threads.append(t)
for i in range (THREAD_NUM):
threads[i].start()
for i in range (THREAD_NUM):
threads[i].join()
if __name__ == '__main__':
