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 ?

WINDOWS ONLY -不敢相信没有人破解Win32_PingStatus 使用一个简单的WMI查询,我们可以免费返回一个包含非常详细信息的对象

import wmi


# new WMI object
c = wmi.WMI()

# here is where the ping actually is triggered
x = c.Win32_PingStatus(Address='google.com')

# how big is this thing? - 1 element
print 'length x: ' ,len(x)


#lets look at the object 'WMI Object:\n'
print x


#print out the whole returned object
# only x[0] element has values in it
print '\nPrint Whole Object - can directly reference the field names:\n'
for i in x:
    print i



#just a single field in the object - Method 1
print 'Method 1 ( i is actually x[0] ) :'
for i in x:
    print 'Response:\t', i.ResponseTime, 'ms'
    print 'TTL:\t', i.TimeToLive


#or better yet directly access the field you want
print '\npinged ', x[0].ProtocolAddress, ' and got reply in ', x[0].ResponseTime, 'ms'

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。

import subprocess
ping_response = subprocess.Popen(["/bin/ping", "-c1", "-w100", "192.168.0.1"], stdout=subprocess.PIPE).stdout.read()

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。
