+  TITLE:=A port-knocking client
+  DESCRIPTION:=It listens to all traffic on an ethernet (or PPP) interface,\\\
+looking for special "knock" sequences of port-hits. A client\\\
+makes these port-hits by sending a TCP (or UDP) packet to a\\\
+port on the server. This port need not be open -- since\\\
+knockd listens at the link-layer level, it sees all traffic\\\
+even if it's destined for a closed port. When the server\\\
+detects a specific sequence of port-hits, it runs a command\\\
+defined in its configuration file. This can be used to open\\\
+up holes in a firewall for quick access.\\\
