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 ?

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

import subprocess
ping_response = subprocess.Popen(["/bin/ping", "-c1", "-w100", "192.168.0.1"], stdout=subprocess.PIPE).stdout.read()
我自己的方法结合了上面的几个答案:
def ping(host, show_log=False, package_count=1):
ping.param = "-n" if platform.system().lower() == 'windows' else "-c"
result = subprocess.run(['ping', ping.param, str(package_count), host],
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT)
output = result.stdout
if show_log:
print('return code: ', result.returncode)
print(output.decode("utf-8"))
return result.returncode == 0 and (b'TTL=' in output or b'ttl=' in output)
在OSX Monterey上测试。
确保安装了pyping或安装它
#!/usr/bin/python
import pyping
response = pyping.ping('Your IP')
if response.ret_code == 0:
print("reachable")
else:
print("unreachable")
#!/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 !")
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"))
