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 ?
当前回答
#!/usr/bin/python3
import subprocess as sp
def ipcheck():
status,result = sp.getstatusoutput("ping -c1 -w2 " + str(pop))
if status == 0:
print("System " + str(pop) + " is UP !")
else:
print("System " + str(pop) + " is DOWN !")
pop = input("Enter the ip address: ")
ipcheck()

import subprocess
ping_response = subprocess.Popen(["/bin/ping", "-c1", "-w100", "192.168.0.1"], stdout=subprocess.PIPE).stdout.read()
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
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'
样例输出
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"))
这个脚本适用于Windows,也适用于其他操作系统: 它可以在Windows, Debian和macosx上工作,需要在solaris上测试。
import os
import platform
def isUp(hostname):
giveFeedback = False
if platform.system() == "Windows":
response = os.system("ping "+hostname+" -n 1")
else:
response = os.system("ping -c 1 " + hostname)
isUpBool = False
if response == 0:
if giveFeedback:
print hostname, 'is up!'
isUpBool = True
else:
if giveFeedback:
print hostname, 'is down!'
return isUpBool
print(isUp("example.com")) #Example domain
print(isUp("localhost")) #Your computer
print(isUp("invalid.example.com")) #Unresolvable hostname: https://tools.ietf.org/html/rfc6761
print(isUp("192.168.1.1")) #Pings local router
print(isUp("192.168.1.135")) #Pings a local computer - will differ for your network
