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