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
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

#!/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 !")

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
有一个名为pyping的模块可以做到这一点。可以用pip安装
pip install pyping
它使用起来非常简单,但是,当使用这个模块时,您需要root访问权限,因为它在底层制作原始数据包。
import pyping
r = pyping.ping('google.com')
if r.ret_code == 0:
print("Success")
else:
print("Failed with {}".format(r.ret_code))
下面是一个使用Python的子进程模块和底层操作系统提供的ping CLI工具的解决方案。在Windows和Linux上测试。支持设置网络超时。不需要根权限(至少在Windows和Linux上)。
import platform
import subprocess
def ping(host, network_timeout=3):
"""Send a ping packet to the specified host, using the system "ping" command."""
args = [
'ping'
]
platform_os = platform.system().lower()
if platform_os == 'windows':
args.extend(['-n', '1'])
args.extend(['-w', str(network_timeout * 1000)])
elif platform_os in ('linux', 'darwin'):
args.extend(['-c', '1'])
args.extend(['-W', str(network_timeout)])
else:
raise NotImplemented('Unsupported OS: {}'.format(platform_os))
args.append(host)
try:
if platform_os == 'windows':
output = subprocess.run(args, check=True, universal_newlines=True).stdout
if output and 'TTL' not in output:
return False
else:
subprocess.run(args, check=True)
return True
except (subprocess.CalledProcessError, subprocess.TimeoutExpired):
return False
使用Multi-ping (pip install multiPing),我做了这个简单的代码(简单地复制和粘贴,如果你愿意!):
from multiping import MultiPing
def ping(host,n = 0):
if(n>0):
avg = 0
for i in range (n):
avg += ping(host)
avg = avg/n
# Create a MultiPing object to test hosts / addresses
mp = MultiPing([host])
# Send the pings to those addresses
mp.send()
# With a 1 second timout, wait for responses (may return sooner if all
# results are received).
responses, no_responses = mp.receive(1)
for addr, rtt in responses.items():
RTT = rtt
if no_responses:
# Sending pings once more, but just to those addresses that have not
# responded, yet.
mp.send()
responses, no_responses = mp.receive(1)
RTT = -1
return RTT
用法:
#Getting the latency average (in seconds) of host '192.168.0.123' using 10 samples
ping('192.168.0.123',10)
如果你想要一个单一的样本,第二个参数“10”可以忽略!
希望能有所帮助!
