Types

type Callback

type Callback g.CaptureCallbackFunc

Callback provides a custom callback function which is called for each captured packet

func (Callback) Apply

func (cb Callback) Apply(c *g.Capture)

type CaptureLength

type CaptureLength int

func (CaptureLength) Apply

func (sl CaptureLength) Apply(c *g.Capture)

type Channel

type Channel chan g.CapturePacket

Channel sends all captured packets to the provided channel.

func ToChannel

func ToChannel(ch chan g.CapturePacket) Channel

func (Channel) Apply

func (d Channel) Apply(c *g.Capture)

type Comment

type Comment string

Comment can be used to add a custom comment to the PCAPng file

func (Comment) Apply

func (d Comment) Apply(c *g.Capture)

type File

type File struct {
	*os.File
}

File writes all captured packets to a file handle

func ToFile

func ToFile(f *os.File) File

func (File) Apply

func (f File) Apply(c *g.Capture)

type Filename

type Filename string

Filename writes all captured packets to a PCAPng file

func ToFilename

func ToFilename(fn string) Filename

func (Filename) Apply

func (fn Filename) Apply(c *g.Capture)

type FilterExpression

type FilterExpression string

FilterExpression is a libpcap filter expression See: https://www.tcpdump.org/manpages/pcap-filter.7.html

func (FilterExpression) Apply

func (bpf FilterExpression) Apply(c *g.Capture)

type FilterInstructions

type FilterInstructions []bpf.Instruction

FilterInstructions allows filtering the captured packets by providing a compiled BPF filter program.

func (FilterInstructions) Apply

func (fi FilterInstructions) Apply(c *g.Capture)

type FilterInterfaces

type FilterInterfaces g.CaptureFilterInterfaceFunc

FilterInterface is a filter callback to limit the interfaces which will be recorded

func (FilterInterfaces) Apply

func (f FilterInterfaces) Apply(c *g.Capture)

type FilterPackets

type FilterPackets g.CaptureFilterPacketFunc

FilterPackets is a callback to filter packets within the Go application rather via BPF in the kernel

func (FilterPackets) Apply

func (f FilterPackets) Apply(c *g.Capture)

type Promiscuous

type Promiscuous bool

func (Promiscuous) Apply

func (p Promiscuous) Apply(c *g.Capture)
