Types

type Source

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

func NewPacketSource

func NewPacketSource(iface string, vpnMode bool) (*Source, error)

func (*Source) Close

func (s *Source) Close()

func (*Source) ReadPacketData

func (s *Source) ReadPacketData() ([]byte, *gopacket.CaptureInfo, error)

func (*Source) SetBPFFilter

func (s *Source) SetBPFFilter(bpfFilter string, maxPacketLength int) error

maxPacketLength is the maximum size of packets to capture in bytes. pcap calls it "snaplen" and default value used in tcpdump is 262144 bytes, that is redundant for most scans, see pcap(3) and tcpdump(1) for more info

func (*Source) WritePacketData

func (s *Source) WritePacketData(pkt []byte) error
