Types

type IcmpStats 

type IcmpStats struct {
	Valid   bool
	RTT     time.Duration
	Tracker int64
	Seq     uint16
}

type Packet 

type Packet struct {
	Proto ProtocolVersion // protocol: 4=IPv4, 6=IPv6
	Bytes []byte          // Marshaled package
	Len   int             // length of package
	TTL   int             // TTL of the packet (currently unused)
	Addr  netip.Addr      // Dest address for sending package and Src address ro received
}

type Pinger 

type Pinger struct {
	// Size of packet being sent
	Size int

	// Tracker: Used to uniquely identify packet when non-priviledged
	Tracker int64
	// contains filtered or unexported fields
}

Pinger represents a packet sender.

func NewPinger 

func NewPinger(network, protocol string, id uint16) *Pinger

NewPinger returns a new Pinger instance

func (*Pinger) ParsePacket 

func (p *Pinger) ParsePacket(recv *Packet) IcmpStats

func (*Pinger) PrepareICMP 

func (p *Pinger) PrepareICMP(addr netip.Addr, seq uint16) (*Packet, error)

func (*Pinger) Privileged 

func (p *Pinger) Privileged() bool

Privileged returns whether pinger is running in privileged mode.

func (*Pinger) RecvICMP 

func (p *Pinger) RecvICMP(proto ProtocolVersion) IcmpStats

func (*Pinger) RecvPacket 

func (p *Pinger) RecvPacket(proto ProtocolVersion) (*Packet, error)

func (*Pinger) SendICMP 

func (p *Pinger) SendICMP(addr netip.Addr, sequence uint16) error

func (*Pinger) SendPacket 

func (p *Pinger) SendPacket(pkt *Packet) error

func (*Pinger) SetConns 

func (p *Pinger) SetConns(c4 *icmp.PacketConn, c6 *icmp.PacketConn)

SetConns setups IPv4 and IPv6 connections to pinger

func (*Pinger) SetPrivileged 

func (p *Pinger) SetPrivileged(privileged bool)

SetPrivileged sets the type of ping pinger will send. false means pinger will send an "unprivileged" UDP ping. true means pinger will send a "privileged" raw ICMP ping. NOTE: setting to true requires that it be run with super-user privileges.

type ProtocolVersion 

type ProtocolVersion int
