25 define Package/knock/Default
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.
