[olug] New PortKnocking Script

[Thom Harrison]

I've updated the newest PortKnocking Scripts.  They now allow the opening of 
ports up to 65,535.  Before the limitation was 255.

I also modified it to send a timestamp accurate to the minute.  The server must 
calculate the same timestamp.  This means that any given portknocking sequence 
is only valid for up to 1 minute.  It also means that you'll need to have xntpd 
running.
