12 It listens to all traffic on an ethernet (or PPP) interface,
13 looking for special "knock" sequences of port-hits. A client
14 makes these port-hits by sending a TCP (or UDP) packet to a
15 port on the server. This port need not be open -- since
16 knockd listens at the link-layer level, it sees all traffic
17 even if it's destined for a closed port. When the server
18 detects a specific sequence of port-hits, it runs a command
19 defined in its configuration file. This can be used to open
20 up holes in a firewall for quick access.
