Linux for beginners course

I have installed putty and it wont let me finish the config because i’m not connected to a server. Do I just make a server? how do I get this to continue?

It sounds like you’re at the point where PuTTY would have you create a new session by entering the IP address of a server. If that’s the case, then yes, you could create a virtual machine to connect to. If you do create a virtual machine, though, you’re usually better off using the VM engine’s console to connect - PuTTY is best used to connect to remote servers.
