I just started goofing off with Kali Linux (metasploit against a metasploitable image) and had installed it to virtualbox. I tried to install Guest Additions so as to be able to make the screen match my actual monitor and allow for fullscreening. In trying to do that, I was told I needed kernel headers for the 4.7 kernel, but the Kali I just installed (2016.2 version) was running on the 4.

So I have been trying to figure this out. I am supposed to be able to do some port forwarding, which isn’t hard, but it wasn’t working. Eventually I went with the option of setting up two network adapters, one set up on NAT (so the VM can access the www) and another as a host-only, so the host can access the guest on 192.168.x.x I was having a problem though, it was refusing me.
