Has anyone seen (or written) any port knocking implementations in Ruby?
I couldn't see any in the RAA or RubyForge (unless it's under a name I
missed).  Is there any interest for this sort of thing?  I wrote a
mini-script to do it with ICMP but I'm not a programmer and it most
likely bites.

It requires libpcap and ruby-libpcap. Suggestions are welcome. I wanted
to be able to knock without a client, hence the ping thing.
