在Python中对服务器进行ping测试

在Windows或Linux中全部ping一遍，返回排序后的列表。这是对@Ahmed Essam和@Arno回答的混合/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))

很多答案都忽略了一件事情（至少在Windows中），即ping命令如果收到“目标主机不可达”的回复，则返回0（表示成功）。
以下是我的代码，它检查响应中是否存在b'TTL='，因为只有当ping到达主机时才会出现这个。注意：这段代码大部分基于其他答案。

import platform
import subprocess

def ping(ipAddr, timeout=100):
    '''
    Send a ping packet to the specified host, using the system ping command.
    Accepts ipAddr as string for the ping destination.
    Accepts timeout in ms for the ping timeout.
    Returns True if ping succeeds otherwise Returns False.
        Ping succeeds if it returns 0 and the output includes b'TTL='
    '''
    if platform.system().lower() == 'windows':
        numFlag = '-n'
    else:
        numFlag = '-c'
    completedPing = subprocess.run(['ping', numFlag, '1', '-w', str(timeout), ipAddr],
                                   stdout=subprocess.PIPE,    # Capture standard out
                                   stderr=subprocess.STDOUT)  # Capture standard error
    # print(completedPing.stdout)
    return (completedPing.returncode == 0) and (b'TTL=' in completedPing.stdout)

print(ping('google.com'))

注意：这里捕获的是输出而不是打印，因此如果您想要看到ping的输出，您需要在返回之前打印completedPing.stdout。

我在一分钟内编写的一个简单程序..使用icmp库需要root权限，下面的代码运行得非常好！HTH
