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