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