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

#!/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 !")

import subprocess
ping_response = subprocess.Popen(["/bin/ping", "-c1", "-w100", "192.168.0.1"], stdout=subprocess.PIPE).stdout.read()

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

WINDOWS ONLY -不敢相信没有人破解Win32_PingStatus 使用一个简单的WMI查询,我们可以免费返回一个包含非常详细信息的对象

import wmi


# new WMI object
c = wmi.WMI()

# here is where the ping actually is triggered
x = c.Win32_PingStatus(Address='google.com')

# how big is this thing? - 1 element
print 'length x: ' ,len(x)


#lets look at the object 'WMI Object:\n'
print x


#print out the whole returned object
# only x[0] element has values in it
print '\nPrint Whole Object - can directly reference the field names:\n'
for i in x:
    print i



#just a single field in the object - Method 1
print 'Method 1 ( i is actually x[0] ) :'
for i in x:
    print 'Response:\t', i.ResponseTime, 'ms'
    print 'TTL:\t', i.TimeToLive


#or better yet directly access the field you want
print '\npinged ', x[0].ProtocolAddress, ' and got reply in ', x[0].ResponseTime, 'ms'

样例输出

此函数适用于任何操作系统(Unix、Linux、macOS和Windows) Python 2和Python 3

编辑: @radato os。System被subprocess.call取代。这避免了在没有验证主机名字符串的情况下shell注入漏洞。

import platform    # For getting the operating system name
import subprocess  # For executing a shell command

def ping(host):
    """
    Returns True if host (str) responds to a ping request.
    Remember that a host may not respond to a ping (ICMP) request even if the host name is valid.
    """

    # Option for the number of packets as a function of
    param = '-n' if platform.system().lower()=='windows' else '-c'

    # Building the command. Ex: "ping -c 1 google.com"
    command = ['ping', param, '1', host]

    return subprocess.call(command) == 0

注意,根据Windows上的@ikrase,如果你得到一个目标主机不可达错误,这个函数仍然会返回True。

解释

该命令在Windows和类unix系统中都是ping。 选项-n (Windows)或-c (Unix)控制包的数量,在本例中设置为1。

platform.system()返回平台名称。前女友。macOS上的“达尔文”。 Subprocess.call()执行一个系统调用。例如subprocess.call ([' ls ', ' - l '])。

我的解决方法是:

def ping(self, host):
    res = False

    ping_param = "-n 1" if system_name().lower() == "windows" else "-c 1"

    resultado = os.popen("ping " + ping_param + " " + host).read()

    if "TTL=" in resultado:
        res = True
    return res

“TTL”是判断ping是否正确的方法。 Saludos
