define Package/knock/Default
  SECTION:=net
  CATEGORY:=Network
  DEPENDS:=+libpcap
  TITLE:=Port-knocking
  DESCRIPTION:=\
	It listens to all traffic on an ethernet (or PPP) interface, \\\
	looking for special "knock" sequences of port-hits. A client \\\
	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.
