在日常的工作中,我們通常會有去探測目標主機是否存活的應用場景,單個的服務器主機可以通過計算機自帶的DOS命令來執行,但是業務的存在往往不是單個存在的,通常都是需要去探測C段的主機(同一個網段下的存活主機),這樣使用DOS來進行操作是不可取,探測的速度太慢了,不滿足實際需要。一般批量的操作需要使用腳本進行一鍵部署執行,本文主要通過使用Python語言來實現批量ping的操作(使用多線程實現Python批量處理)
Python版本 :Python3
使用的第三方庫:subprocess, logging, threading, queue
日志導出模塊功能:
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)
多線程實現批量操作:
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()

)
console = logging.StreamHandler()
console.setLevel(logging.INFO)
formatter = logging.Formatter('%(message)s')
console.setFormatter(formatter)
logging.getLogger('').addHandler(console)
# 將需要ping 連接的IP加入隊列

# print (IP_list())

#print (ip)

#print (res)
if res == 0:
h =subprocess.getoutput('ping' + ' ' + ip)
#print (h)
if 'TTL=' in h:
res = ('網絡可以正常連通平均延時 = %s' % h.split('平均 = ')[1])
else:
res = '網絡連接失敗!'
today = datetime.datetime.now().strftime("%Y - %m - %d %H : %M : %S")
logging.info("%s IP = %s %s" % (today,ip,res))
