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
我使用这篇文章中回答的想法,但只使用更新的推荐子进程模块和python3:
import subprocess
import platform
operating_sys = platform.system()
nas = '192.168.0.10'
def ping(ip):
# ping_command = ['ping', ip, '-n', '1'] instead of ping_command = ['ping', ip, '-n 1'] for Windows
ping_command = ['ping', ip, '-n', '1'] if operating_sys == 'Windows' else ['ping', ip, '-c 1']
shell_needed = True if operating_sys == 'Windows' else False
ping_output = subprocess.run(ping_command,shell=shell_needed,stdout=subprocess.PIPE)
success = ping_output.returncode
return True if success == 0 else False
out = ping(nas)
print(out)

看起来很简单,但却让我头疼。我一直得到“icmp打开套接字操作不允许”,否则解决方案将挂起,如果服务器离线。然而,如果你想知道的是服务器是活的,并且你在该服务器上运行一个web服务器,那么curl将完成这项工作。如果您有ssh和证书,那么ssh和一个简单的命令就足够了。代码如下:
from easyprocess import EasyProcess # as root: pip install EasyProcess
def ping(ip):
ping="ssh %s date;exit"%(ip) # test ssh alive or
ping="curl -IL %s"%(ip) # test if http alive
response=len(EasyProcess(ping).call(timeout=2).stdout)
return response #integer 0 if no response in 2 seconds
我的解决方法是:
def ping(self, host):
res = False
ping_param = "-n 1" if system_name().lower() == "windows" else "-c 1"
resultado = os.popen("ping " + ping_param + " " + host).read()
if "TTL=" in resultado:
res = True
return res
“TTL”是判断ping是否正确的方法。 Saludos
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!
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
我在类似的情况下找到了这个问题。我尝试了pyping,但Naveen给出的例子在Python 2.7下的Windows中对我不起作用。
一个对我有用的例子是:
import pyping
response = pyping.send('Your IP')
if response['ret_code'] == 0:
print("reachable")
else:
print("unreachable")
