Multiple-port knocking Netfilter/IPtables only implementation

There are several methods of implementing port knocking (the sophisticated project Knockd for instance). Here we'll demonstrate a very simple means of achieving the port-knocking effect using nothing more than netfilter, or iptables, rules. You will need the iptables "recent" module compiled in you kernel or as a module - we've previously introduced using this to rate-limit incoming connections with the recent module.
