如果您的服务器不支持ICMP(防火墙可能会阻止它)，它很可能仍然在TCP端口上提供服务。在这种情况下，你可以像这样执行TCP ping1(平台独立，无需安装额外的python模块):

import socket

def isReachable(ipOrName, port, timeout=2):
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.settimeout(timeout)
    try:
        s.connect((ipOrName, int(port)))
        s.shutdown(socket.SHUT_RDWR)
        return True
    except:
        return False
    finally:
        s.close()

代码从这里开始只做了轻微的修改。

1 TCP ping并不真正存在，因为ping是在ISO/OSI第三层用ICMP执行的。TCP ping在ISO/OSI第4层执行。它只是试图以最基本的方式连接到TCP端口，即不传输任何数据，而是在连接后立即关闭连接。

我的版本的ping函数:

适用于Python 3.5及更高版本，适用于Windows和Linux。 在Windows上，如果ping命令失败且“目标主机不可达”，则返回False。 并且不显示任何输出，无论是弹出窗口还是命令行。

import platform, subprocess

def ping(host_or_ip, packets=1, timeout=1000):
    ''' Calls system "ping" command, returns True if ping succeeds.
    Required parameter: host_or_ip (str, address of host to ping)
    Optional parameters: packets (int, number of retries), timeout (int, ms to wait for response)
    Does not show any output, either as popup window or in command line.
    Python 3.5+, Windows and Linux compatible
    '''
    # The ping command is the same for Windows and Linux, except for the "number of packets" flag.
    if platform.system().lower() == 'windows':
        command = ['ping', '-n', str(packets), '-w', str(timeout), host_or_ip]
        # run parameters: capture output, discard error messages, do not show window
        result = subprocess.run(command, stdin=subprocess.DEVNULL, stdout=subprocess.PIPE, stderr=subprocess.DEVNULL, creationflags=0x08000000)
        # 0x0800000 is a windows-only Popen flag to specify that a new process will not create a window.
        # On Python 3.7+, you can use a subprocess constant:
        #   result = subprocess.run(command, capture_output=True, creationflags=subprocess.CREATE_NO_WINDOW)
        # On windows 7+, ping returns 0 (ok) when host is not reachable; to be sure host is responding,
        # we search the text "TTL=" on the command output. If it's there, the ping really had a response.
        return result.returncode == 0 and b'TTL=' in result.stdout
    else:
        command = ['ping', '-c', str(packets), '-w', str(timeout), host_or_ip]
        # run parameters: discard output and error messages
        result = subprocess.run(command, stdin=subprocess.DEVNULL, stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)
        return result.returncode == 0

你想怎么用就怎么用。

#!/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 !")

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

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
