My Raspberry Pi 3 Kali Linux Headless Setup

hey,
i have a raspberry pi4 and want to use khali linux on it. My only problem is: i don't have a mini hdmi cable, so got no monitor connected.


I am trying to sertup khali linux headless, but I can't connect to the raspberry with SSH (putty). (Connection refused)
Is there any chance you could give me advise how to connect to a khali linux raspberry with putty.


btw: i am using windows

Figured I would make another update just not a full video on it right now. I did add more programs and made some more custom .sh scripts I even got rid of the text banner with the commands and replaced it with with a single command sh script that has a number selection so I won't have to rely on the terminals history to input commands plus it auto launches at sign in. Also added airbase and a few other mitm tools I like as well as some keylogger generators.
