Mr. Fulvio,

I posted a Request for a Feature about FWKNOP that can help solve that problem by effectively hiding the SSH until you send some authorization packet (like Port Knocking but single packet with cryptography).

This way, not only a SCAN would do absolutely nothing (it would not respond to any request), you can protect vulnerable services from remote access even before a patch is available by limiting who can reach the service.

Thanks again for your work on providing this excellent woftware that is Zeroshell.
