DrKnock is a port knocking solution based on sig2knock by Cappella and Tan Chew Keong (http://www.security.org.sg/code/portknock1.html). The client and server work on both Unix and Windows.

Release Notes: A code cleanup was undertaken and bugs were fixed. The last occurrences of sig2knock were replaced by drknock, including the Windows service name and log file.
Release Notes: The client can now choose among multiple services to be forwarded to, and select a range of possible ports for the randomly allocated port (if allowed by server). User and password can be set via client command line. If wanted, multiple connections can be made to the allocated port. The configuration file format has changed
Release Notes: The knocking method was changed from SYN packets to UDP packets (to work with Windows XP SP2). The server and client, both for Linux and Windows, are now under the same code tree. Packet structs were changed to work with 64-bit architectures.
