  38 =
  39         It listens to all traffic on an ethernet (or PPP) interface,
  40         looking for special "knock" sequences of port-hits. A client
  41         makes these port-hits by sending a TCP (or UDP) packet to a
  42         port on the server. This port need not be open -- since
  43         knockd listens at the link-layer level, it sees all traffic
  44         even if it's destined for a closed port. When the server
  45         detects a specific sequence of port-hits, it runs a command
  46         defined in its configuration file. This can be used to open
  47         up holes in a firewall for quick access.
  48         This package contains the port-knocking client.
