Capture the trafic using libpcap

func New

func New(device string) (*CaptureContext, error)

Creates a capture context using libpcap implementation and opens the device to capture. Ensure that the process has permission con capture traffic through the device.

func (*CaptureContext) Close

func (c *CaptureContext) Close()

Ends with the capture session

func (*CaptureContext) GetMAC

func (c *CaptureContext) GetMAC() net.HardwareAddr

Gets the MAC Address of the device being captured.

func (*CaptureContext) Packets

func (c *CaptureContext) Packets() chan *capture.Packet

Returns the packets channel where all the packets will be passed through.

func (*CaptureContext) StartCapturing

func (c *CaptureContext) StartCapturing()

Starts the capture session. Use Packets() to grab the packets channel.
