For the three people who downloaded this before… You REALLY need  
to download this one.

fire version 1.2.0 has been released!

- [http://fire.rubyforge.com/](http://fire.rubyforge.com/)

## SYNOPSIS:

Here’s how to set up a Port Knocking Daemon with a key of ports 15,  
99, and 1632!  
When the password is accepted, it says “hello, world”:

class MyPorter \< Porter

rule\_set :normal { |pkt|  
rule { pkt.tcp? }  
rule { Time.now - $pkt.knock(1).time == 3 }

}

rule\_set :mondays { |pkt|  
rule { false} #=\> Always fails  
}

accept :mondays {  
puts “DIEEEEEEEE”  
}

accept :normal {  
puts “hello, world”  
}

use :normal  
end

MyPorter.new([15, 99, 1632], true)

Here’s how to set up a quick firewall, which saves it as an IPTables  
script:  
Firewall :write, “/Users/ari/Desktop/firewall.sh” do  
@debug = true

Filter do  
chain “extra\_packets”

etc …

English is like a pseudo-random number generator - there are a  
bajillion rules to it, but nobody cares.
