我需要写一个Python脚本，它可以告诉我“我是否连接到虚拟专用网络”，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，它可以给出一个二进制结果来检查我的机器是否连接到Corporate_VPN (Connection_Name)或没有连接到Corporate_VPN。

我已经尝试了一些文章和帖子，我可以找到，但没有成功。下面是一些例子：

我试过这个帖子：Getting Connected VPN Name in Python

并尝试：

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

我得到了这个错误：

    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'

当我尝试"pip install python-NetworManager“时，我得到了这个错误：

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

我也尝试了下面的帖子，但没有任何帮助：https://www.reddit.com/r/learnpython/comments/5qkpu1/python_script_to_check_if_connected_to_vpn_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")

抛出错误：

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

我不确定我现在做错了什么。注:我在公司VPN连接中执行所有这些操作。

Answer 1

pip install python-NetworManager

错误: WinError 193 %1不是有效的Win32应用程序

NetworManager是Linux-only应用程序。

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

IP地址必须是字符串：

    host = '192.168.*.*'

Answer 2

这是告诉你是否连接到VPN的代码。

注意:每次连接到VPN时，VPN上计算机的 IPv4地址可能会更改。

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")
