Package knock-server

http://www.zeroflux.org/projects/knock

Knock is a port-knocking server/client. Port-knocking is a method where a
server can sniff one of its interfaces for a special "knock" sequence of
port-hits. When detected, it will run a specified event bound to that port
knock sequence. These port-hits need not be on open ports, since we use
libpcap to sniff the raw interface traffic. This package contains the
knockd server.
