Cryptographically Hiding TCP Ports

JohnGrahamCumming writes "The shimmer project implements a cryptographically-based system for hiding important (e.g. SSH) open ports in plain sight. By automatically forwarding from a range of ports all but one of which are honeypots and by changing the ports every minute only a user knowing a shared secret can determine the location of the real SSH server."

If your ntp-enabled systems are drifting 15 seconds out of whack with each other, you have bigger problems than additional SSH security.
