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

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

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

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)

  1 #!/usr/bin/python
  2
  3 import os
  4 import sys
  5 import time
  6
  7 os.system("clear")
  8 home_network = "172.16.23."
  9 mine = []
 10
 11 for i in range(1, 256):
 12         z =  home_network + str(i)
 13         result = os.system("ping -c 1 "+ str(z))
 14         os.system("clear")
 15         if result == 0:
 16                 mine.append(z)
 17
 18 for j in mine:
 19         print "host ", j ," is up"

一个简单的我只是在一分钟内煮出来的..使用icmplib需要根privs下面的工作非常好! HTH

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。
