Description : This is a port-knocking server/client. Port-knocking is a method where a
: server can sniff one of its interfaces for a special "knock" sequence of
: port-hits. When detected, it will run a specified event bound to that port
: knock sequence. These port-hits need not be on open ports, since we use
: libpcap to sniff the raw interface traffic. This package contains the
: knock client.
