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
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。

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
#!/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()
#!/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"))
