我需要编写一个 Python 脚本，它可以告诉我"If I am connected to VPN or NOT"进一步使用它作为Test_Case：

Question

现在，我正在尝试编写一个python脚本，该脚本可以给出二进制结果，以检查我的计算机是连接到Corporate_VPN（Connection_Name）还是未连接到Corporate_vpn。

我尝试了很少的文章和文章，但我可以找到这些文章，但没有成功。这是一些：

我尝试了这篇文章：在Python中获得连接的VPN名称

试验：

import NetworkManager
for conn in NetworkManager.NetworkManager.ActiveConnections:
    print('Name: %s; vpn?: %s' % (conn.Id, conn.Vpn))

我遇到了这个错误：

    ImportError                               
    Traceback (most recent call last)
    <ipython-input-6-52b1e422fff2> in <module>()
    ----> 1 import NetworkManager
          2 
          3 for conn in NetworkManager.NetworkManager.ActiveConnections:
          4     print('Name: %s; vpn?: %s' % (conn.Id, conn.Vpn))
    ImportError: No module named 'NetworkManager'

当尝试" pip install python-netnemanager"时，我得到了这个错误：

稍后，当我尝试" pip install dbus python"时，我得到了这个错误：

我还尝试关注帖子，也没有帮助：https：//www.reddit.com/r/learnpython/comments/5qkpu1/python_script_to_check_check_check_connection_to_to_to_to_vpn_or_or_not/

host = *******
ping = subprocess.Popen(["ping.exe","-n","1","-w","1",host],stdout = subprocess.PIPE).communicate()[0]
if ('unreachable' in str(ping)) or ('timed' in str(ping)) or ('failure' in str(ping)):
    ping_chk = 0
else:
    ping_chk = 1 
 if ping_chk == 1:
     print ("VPN Connected")
 else:
    print ("VPN Not Connected")

抛出我错误：

File "<ipython-input-5-6f992511172f>", line 1
    host = 192.168.*.*
                   ^
SyntaxError: invalid syntax

我不确定我现在在做什么。注意：我在Corporate VPN Connection中做所有这些。

Answer 1

pip install python-NetworManager

错误：[WinError 193]％1不是有效的Win32应用程序

net虫子是只有Linux的应用。

    host = 192.168.*.*
                   ^
SyntaxError: invalid syntax

IP地址必须是字符串：

    host = '192.168.*.*'

Answer 2

这是代码，它告诉您是否已连接到VPN。

注意： IPv4机器上VPN上的Adress每次连接到VPN时可能会更改。

import subprocess
host = '**.***.***.***' 
#IPv4 should be string ''
#IPv4 Address (while connected to VPN in command prompt type: ipconfig",
copy IPv4 Address digits and paste as "host = ", 
#IPv4 Address. changes each time we freshly connect to VPN. )
ping = subprocess.Popen(["ping.exe","-n","1","-w","1",host],stdout = subprocess.PIPE).communicate()[0]
if ('unreachable' in str(ping)) or ('timed' in str(ping)) or ('failure' in str(ping)):
    ping_chk = 0
else:
    ping_chk = 1 
if ping_chk == 1:
     print ("VPN Connected")
else:
    print ("VPN Not Connected")
