Me>tor>vpn

Hello! Please, help a noobie to make this easy thing.

I have an experience with TailsOS only and i never used any commands in terminal. I have configuration files (.ovpn). I have installed OpenVPN by using this command
sudo apt-get install openvpn

After that i need to connect to the VPN using ,y configuration file. What command i should write in the terminal? Thanks!

No easy way. See documentation:

Thank you! But i have read it a few times and didn’t understand ho to do what i need. I have found on the other website instruction with this command
sudo openvpn --client --dev tun --config CONFIGURATION_FILE_NAME --proto tcp
and it actually works!
Now i have another questions.

  1. Why i can’t find it at the official website (link wich you send here)?
  2. How to disconnect from the VPN by terminal command?
  3. Is it normal that after making VPN-connection and Whonixchek i see;
    ERROR: TransPort Test Result:
    Looks like you are not connected through Tor!
    IP: ********* (here i see my VPN IP)
