Knocker, a knock based access control system for your homelab

I will never, ever understand this "single-packet authentication" "port knocking" fetish. It has never made sense. Bin it, along with fail2ban, and just set up WireGuard.

Your network authentication should not be a fun game or series of Rube Goldberg contraptions.

Fail2ban is not in the same realm as port knocking, and to "bin it" would be foolish security posture at best, and negligent at worst.

I’m not super familiar with the intricacies of fail2ban and don’t currently understand why op made that claim but would very much like to know more because he is talking about a topic he is highly regarded for and I respect that. I just don’t have the context.
