在Python中,是否有一种方法可以通过ICMP来ping服务器,如果服务器响应则返回TRUE,如果没有响应则返回FALSE ?


当前回答

我在类似的情况下找到了这个问题。我尝试了pyping,但Naveen给出的例子在Python 2.7下的Windows中对我不起作用。

一个对我有用的例子是:

import pyping

response = pyping.send('Your IP')

if response['ret_code'] == 0:
    print("reachable")
else:
    print("unreachable")

使用这个,它在python 2.7上测试过,工作很好,如果成功,它返回以毫秒为单位的ping时间,失败时返回False。

import platform,subproccess,re
def Ping(hostname,timeout):
    if platform.system() == "Windows":
        command="ping "+hostname+" -n 1 -w "+str(timeout*1000)
    else:
        command="ping -i "+str(timeout)+" -c 1 " + hostname
    proccess = subprocess.Popen(command, stdout=subprocess.PIPE)
    matches=re.match('.*time=([0-9]+)ms.*', proccess.stdout.read(),re.DOTALL)
    if matches:
        return matches.group(1)
    else: 
        return False

我有类似的要求,所以我实现它如下所示。它在Windows 64位和Linux上进行了测试。

import subprocess
def systemCommand(Command):
    Output = ""
    Error = ""     
    try:
        Output = subprocess.check_output(Command,stderr = subprocess.STDOUT,shell='True')
    except subprocess.CalledProcessError as e:
        #Invalid command raises this exception
        Error =  e.output 

    if Output:
        Stdout = Output.split("\n")
    else:
        Stdout = []
    if Error:
        Stderr = Error.split("\n")
    else:
        Stderr = []

    return (Stdout,Stderr)

#in main
Host = "ip to ping"
NoOfPackets = 2
Timeout = 5000 #in milliseconds
#Command for windows
Command = 'ping -n {0} -w {1} {2}'.format(NoOfPackets,Timeout,Host)
#Command for linux 
#Command = 'ping -c {0} -w {1} {2}'.format(NoOfPackets,Timeout,Host)
Stdout,Stderr = systemCommand(Command)
if Stdout:
   print("Host [{}] is reachable.".format(Host))
else:
   print("Host [{}] is unreachable.".format(Host))

当IP不可达时,subprocess.check_output()将引发异常。额外的验证可以通过从输出行“Packets: Sent = 2, Received = 2, Lost = 0 (0% loss)”中提取信息来完成。

确保安装了pyping或安装它

#!/usr/bin/python
import pyping

response = pyping.ping('Your IP')

if response.ret_code == 0:
    print("reachable")
else:
    print("unreachable")
  1 #!/usr/bin/python
  2
  3 import os
  4 import sys
  5 import time
  6
  7 os.system("clear")
  8 home_network = "172.16.23."
  9 mine = []
 10
 11 for i in range(1, 256):
 12         z =  home_network + str(i)
 13         result = os.system("ping -c 1 "+ str(z))
 14         os.system("clear")
 15         if result == 0:
 16                 mine.append(z)
 17
 18 for j in mine:
 19         print "host ", j ," is up"

一个简单的我只是在一分钟内煮出来的..使用icmplib需要根privs下面的工作非常好! HTH

#!/usr/bin/python3

import subprocess as sp

ip = "192.168.122.60"
status,result = sp.getstatusoutput("ping -c1 -w2 " + ip)

if status == 0: 
    print("System " + ip + " is UP !")
else:
    print("System " + ip + " is DOWN !")
