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.
