Is it possible to create one .bat file for connecting and disconnecting to the internet?

Question

cmd/bat

I found this .bat file to connect:

cd %systemroot%\system32 
start rasdial [имя_подключения] [имя_пользователя] [пароль]

and this one to disable:

cd %systemroot%\system32 
start rasdial [имя_подключения] /disconnect

I need one file! - or a simple .bat or other script that would check if there is an Internet connection, and if so, then turn it off, and if not, then connect it.
Thank you!

Answer 1

Given the idea of ​​GavriKos :

ping -n 2 8.8.8.8|Find /I "TTL="||goto no_inet

cd %systemroot%\system32 
start rasdial [имя_подключения] /disconnect
goto end

:no_inet
cd %systemroot%\system32 
start rasdial [имя_подключения] [имя_пользователя] [пароль]

:end

Answer 2

Python is in your hands. Ping 8.8.8.8, and depending on the availability, choose what to do. You can directly rasdial from Python and call it, if that.

Answer 3

powershell script, but will run from a bat file if you have Windows 8 and higher
If the OS is lower than Windows 8, then here is the contents of the batch file:

ping хост -n 1 > %TEMP%\ping1.txt
if %errorlevel%==1 (rasdial название_ВПН_соединения логин пароль) else (rasdial название_ВПН_соединения /disconnect)

In the second case, you need to choose the right host to ping:
If you have an Internet connection like this, then it must be a public host from the Internet (for example 8.8.8.8 ). If you connect to a working network in this way, then the host must be from a working network (inaccessible without an established connection).
