Types

type Conn

type Conn struct {
	Receiver   Receiver
	Privileged bool
	// contains filtered or unexported fields
}

func (*Conn) Close

func (c *Conn) Close()

func (*Conn) Open

func (c *Conn) Open(bind4, bind6 string) error

New creates a new Pinger. This will open the raw socket and start the receiving logic. You'll need to call Close() to cleanup.

func (*Conn) WriteTo

func (c *Conn) WriteTo(addr *net.IPAddr, seq int, data []byte) error

sendRequest marshals the payload and sends the packet. It returns the sequence number and an error if the sending failed.

type Payload

type Payload []byte

Payload represents additional data appended to outgoing ICMP Echo Requests.

func (*Payload) Resize

func (p *Payload) Resize(size uint16)

Resize will assign a new payload of the given size to p.

type Receiver

type Receiver func(body *icmp.Echo, icmpError error, addr net.IPAddr, tRecv *time.Time)
