看起来很简单，但却让我头疼。我一直得到“icmp打开套接字操作不允许”，否则解决方案将挂起，如果服务器离线。然而，如果你想知道的是服务器是活的，并且你在该服务器上运行一个web服务器，那么curl将完成这项工作。如果您有ssh和证书，那么ssh和一个简单的命令就足够了。代码如下:

from easyprocess import EasyProcess # as root: pip install EasyProcess
def ping(ip):
    ping="ssh %s date;exit"%(ip) # test ssh alive or
    ping="curl -IL %s"%(ip)      # test if http alive
    response=len(EasyProcess(ping).call(timeout=2).stdout)
    return response #integer 0 if no response in 2 seconds

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"))

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")

我使用这篇文章中回答的想法，但只使用更新的推荐子进程模块和python3:

import subprocess
import platform

operating_sys = platform.system()
nas = '192.168.0.10'

def ping(ip):
    # ping_command = ['ping', ip, '-n', '1'] instead of ping_command = ['ping', ip, '-n 1'] for Windows
    ping_command = ['ping', ip, '-n', '1'] if operating_sys == 'Windows' else ['ping', ip, '-c 1']
    shell_needed = True if operating_sys == 'Windows' else False

    ping_output = subprocess.run(ping_command,shell=shell_needed,stdout=subprocess.PIPE)
    success = ping_output.returncode
    return True if success == 0 else False

out = ping(nas)
print(out)

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!

下面是一个使用Python的子进程模块和底层操作系统提供的ping CLI工具的解决方案。在Windows和Linux上测试。支持设置网络超时。不需要根权限(至少在Windows和Linux上)。

import platform
import subprocess

def ping(host, network_timeout=3):
    """Send a ping packet to the specified host, using the system "ping" command."""
    args = [
        'ping'
    ]

    platform_os = platform.system().lower()

    if platform_os == 'windows':
        args.extend(['-n', '1'])
        args.extend(['-w', str(network_timeout * 1000)])
    elif platform_os in ('linux', 'darwin'):
        args.extend(['-c', '1'])
        args.extend(['-W', str(network_timeout)])
    else:
        raise NotImplemented('Unsupported OS: {}'.format(platform_os))

    args.append(host)

    try:
        if platform_os == 'windows':
            output = subprocess.run(args, check=True, universal_newlines=True).stdout

            if output and 'TTL' not in output:
                return False
        else:
            subprocess.run(args, check=True)

        return True
    except (subprocess.CalledProcessError, subprocess.TimeoutExpired):
        return False
