Types

type List

type List []Port

List is a list of Ports.

func GetList

func GetList(prev List) (List, error)

func (List) SameInodes

func (a List) SameInodes(b List) bool

func (List) String

func (pl List) String() string

type Poller

type Poller struct {
	// C received the list of ports periodically. It's closed when
	// Run completes, after which Err can be checked.
	C <-chan List

	// Err is the error from the final GetList call. It is only
	// valid to read once C has been closed. Err is nil if Close
	// is called or the context is canceled.
	Err error
	// contains filtered or unexported fields
}

Poller scans the systems for listening ports periodically and sends the results to C.

func NewPoller

func NewPoller() (*Poller, error)

NewPoller returns a new portlist Poller. It returns an error if the portlist couldn't be obtained.

func (*Poller) Close

func (p *Poller) Close() error

func (*Poller) Run

func (p *Poller) Run(ctx context.Context) error

Run runs the Poller periodically until either the context is done, or the Close is called.

type Port

type Port struct {
	Proto   string // "tcp" or "udp"
	Port    uint16 // port number
	Process string // optional process name, if found
	// contains filtered or unexported fields
}

Port is a listening port on the machine.
