+	  makes these port-hits by sending a TCP (or UDP) packet to a 
+	  port on the server. This port need not be open -- since 
+	  knockd listens at the link-layer level, it sees all traffic 
+	  even if it's destined for a closed port. When the server 
+	  detects a specific sequence of port-hits, it runs a command 
+	  defined in its configuration file. This can be used to open 
+	  up holes in a firewall for quick access.
