Variables

var Nameserver string

Nameserver contains the address of a nameserver to use for resolving generated IP addresses to names. If it is empty, the operating system's default nameserver is used.

Types

type Generator

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

Generator generates random Hosts, checking them against blacklists and ensuring that the IP address resolves to a valid PTR (i.e. that the generated Host is likely to exist on the Internet).

func New

func New(icnt, ncnt int) (*Generator, error)

New creates a new Generator. iCnt is the number of goroutines to spawn for generating IP addresses wCnt is the number of goroutines to spawn for resolving and checking hostnames.

func (*Generator) AddrWorkerCount

func (gen *Generator) AddrWorkerCount() int

AddrWorkerCount returns the number of address generator workers.

func (*Generator) IsActive

func (gen *Generator) IsActive() bool

IsActive returns the Generator's active flag.

func (*Generator) NameWorkerCount

func (gen *Generator) NameWorkerCount() int

NameWorkerCount return the number name resolver workers.

func (*Generator) Start

func (gen *Generator) Start()

Start sets the Generator's active flag and spawns the worker goroutines.

func (*Generator) StartAddrWorker

func (gen *Generator) StartAddrWorker()

StartAddrWorker stars another address generation worker.

func (*Generator) StartNameWorker

func (gen *Generator) StartNameWorker()

StartNameWorker starts another name resolution worker.

func (*Generator) Stop

func (gen *Generator) Stop()

Stop clears the Generator's active flag.

func (*Generator) StopAddrWorker

func (gen *Generator) StopAddrWorker()

StopAddrWorker stops one address generation worker.

func (*Generator) StopNameWorker

func (gen *Generator) StopNameWorker()

StopNameWorker stops one name resolution worker.

func (*Generator) System

func (gen *Generator) System() subsystem.ID

System returns the ID of the subsystem, i.e. subsystem.Generator

func (*Generator) WorkerCount

func (gen *Generator) WorkerCount() int

WorkerCount returns the number of active workers.
