firescan-ruby ============= Ruby reference implementation for the Firebind Firescan path scan client This code has been tested to work with Ruby 1.9.3 and Firebind Reflector 1.0. Integration =========== Integrating the Firescan library is straight forward. It uses a single object 'Scan' and a simple callback mechanism using Ruby's built-in Observer feature. Create a Scan object, pass it your handler (something that implements the Observer update method) and run the Scan. A handler update method might look like this: def update(state) case state.current_state when :PORT_COMPLETE puts "Port #{state.port} #{state.description(state.port_result_code)}" when :PORT_START when :PORT_TICK when :SCAN_START when :START_FAILURE when :SCAN_COMPLETE else end end Then create and run a Scan object like this: scan = Firebind::Scan.new('scanme.firebind.com','1-10',:UDP) scan.add_observer myHandler state = scan.scan See the lib/example.rb script for a simple working example.
