>Description:
shimmer is a pair of small programs (a client and a server) to hide a valuable port (such as a hidden web server or SSH) on a public IP address.

shimmer works by cryptographically changing a set of 16 ports (one of which forwards to the real service, and 15 others that lead to a trap to blacklist attackers). The 16 ports change every minute frustrating an attacker, but a legimitate user with access to a secret shared between the client and server can determine the real port, avoid blacklisting, and get a connection.
