Hello I have a problem with kali linux open vpn ı dont have a IP how I can ınstall a vpn to kali linux ?
What exactly are you trying to do?
openvpn is a client / server application, as a client, it doesn’t automatically connect to the internet, only to the server that is allowing the connection.
For example, tryhackme supply openvpn servers they run their attack boxes on, so you would download an openvpn configuration file from tryhackme, open the config file in a terminal which would give you an openvpn session and an IP on their internal networks, (you leave this it running whilst you need the connection open).
If you needed a new terminal session, you would open another tab or window, if you close the original openvpn session, the connection would drop.
