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 ?

import os #to get clear screen
import subprocess as sp #to get system ping
os.system("clear") #clear screen
print('Wait or Press Ctrl+Z to Terminate\n') #notice to terminate or wait
for i in range(255): #0 to 255 loop
    ip='192.168.1.'+str(i) #concatenating str and int
    s,r=sp.getstatusoutput("ping -c1 -w2 " + ip) #ping and store status in s
    if s==0: #if status is 0 equal to pass
        print(ip+" is UP ✓ ") #output
    else: #if status is not 0 equal to fail
        pass #skip and try next ip from loop

#!/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 !")

使用Multi-ping (pip install multiPing),我做了这个简单的代码(简单地复制和粘贴,如果你愿意!):

from multiping import MultiPing

def ping(host,n = 0):
    if(n>0):
        avg = 0
        for i in range (n):
            avg += ping(host)
        avg = avg/n
    # Create a MultiPing object to test hosts / addresses
    mp = MultiPing([host])

    # Send the pings to those addresses
    mp.send()

    # With a 1 second timout, wait for responses (may return sooner if all
    # results are received).
    responses, no_responses = mp.receive(1)


    for addr, rtt in responses.items():
        RTT = rtt


    if no_responses:
        # Sending pings once more, but just to those addresses that have not
        # responded, yet.
        mp.send()
        responses, no_responses = mp.receive(1)
        RTT = -1

    return RTT

用法:

#Getting the latency average (in seconds) of host '192.168.0.123' using 10 samples
ping('192.168.0.123',10)

如果你想要一个单一的样本,第二个参数“10”可以忽略!

希望能有所帮助!

在windows或linux中Ping它们,返回一个排序的列表。这是@Ahmed Essam和@Arno回复的混合/修正。

import asyncio
import re

import platform
isWindows = platform.system()


async def ping(host):
    cmd = 'ping {} {} 1'.format(host, '-n' if isWindows else '-c')
    ping_proc = \
        await asyncio.create_subprocess_shell(cmd, stdout=asyncio.subprocess.PIPE,
                                                      stderr=asyncio.subprocess.PIPE)
    stdout, stderr = await ping_proc.communicate()
    outstr = stdout.decode()

    if ping_proc.returncode == 0:
        delay = int(re.search(r'(?:time=)([\d]*)', outstr).group(1)) if 'time=' in outstr else -1
        if delay >= 0:
            # print('{} {}ms'.format(host, delay))
            return [host, delay]

    return [host, None]


async def ping_all():
    tasks = []

    for i in range(1, 256):
        ip = "192.168.1.{}".format(i)
        task = asyncio.ensure_future(ping(ip))
        tasks.append(task)

    retList = await asyncio.gather(*tasks, return_exceptions=True)
    retList = [x for x in retList if x[1] is not None]
    retList.sort(key=lambda x: int(x[0].split('.')[-1]))

    return retList


loop = asyncio.ProactorEventLoop()
asyncio.set_event_loop(loop)
pingRet = loop.run_until_complete(ping_all())

for ip, d in pingRet:
    print('{:<16s} {}ms'.format(ip, d))

因为我喜欢让我的Python程序在2.7和3版本上通用。在Linux, Mac OS和Windows平台上,我必须修改现有的示例。

# shebang does not work over all platforms
# ping.py  2016-02-25 Rudolf
# subprocess.call() is preferred to os.system()
# works under Python 2.7 and 3.4
# works under Linux, Mac OS, Windows

def ping(host):
    """
    Returns True if host responds to a ping request
    """
    import subprocess, platform

    # Ping parameters as function of OS
    ping_str = "-n 1" if  platform.system().lower()=="windows" else "-c 1"
    args = "ping " + " " + ping_str + " " + host
    need_sh = False if  platform.system().lower()=="windows" else True

    # Ping
    return subprocess.call(args, shell=need_sh) == 0

# test call
print(ping("192.168.17.142"))

如果你不需要支持Windows,这里有一个非常简洁的方法:

import os
hostname = "google.com" #example
response = os.system("ping -c 1 " + hostname)

#and then check the response...
if response == 0:
  print hostname, 'is up!'
else:
  print hostname, 'is down!'

这是因为如果连接失败,ping将返回一个非零值。(实际返回值因网络错误而异。)您还可以使用'-t'选项更改ping超时(以秒为单位)。注意,这将向控制台输出文本。
