Types

type Scanner

type Scanner struct {
	// contains filtered or unexported fields
}

Scanner wraps all the state need to run the portscanner subsystem across multiple worker goroutines.

func New

func New(cnt int) (*Scanner, error)

New creates and returns a fresh Scanner instance.

func (*Scanner) IsActive

func (scn *Scanner) IsActive() bool

IsActive returns state of the Scanner's active flag.

func (*Scanner) Start

func (scn *Scanner) Start()

Start spawns the Scanner's workers.

func (*Scanner) StartOne

func (scn *Scanner) StartOne()

StartOne starts one additional worker.

func (*Scanner) Stop

func (scn *Scanner) Stop()

Stop clears the Scanner's active flag.

func (*Scanner) StopOne

func (scn *Scanner) StopOne()

StopOne tells one worker to stop.

func (*Scanner) System

func (scn *Scanner) System() subsystem.ID

func (*Scanner) WorkerCnt

func (scn *Scanner) WorkerCnt() int

WorkerCnt returns the number of active workers.
