Types ¶

type RADIUS ¶

type RADIUS struct {
	layers.BaseLayer

	Code          RADIUSCode
	Identifier    RADIUSIdentifier
	Length        RADIUSLength
	Authenticator RADIUSAuthenticator
	Attributes    []RADIUSAttribute
}

RADIUS represents a Remote Authentication Dial In User Service layer.

func (*RADIUS) CanDecode ¶

func (radius *RADIUS) CanDecode() gopacket.LayerClass

CanDecode returns the set of layer types that this DecodingLayer can decode.

func (*RADIUS) DecodeFromBytes ¶

func (radius *RADIUS) DecodeFromBytes(data []byte, df gopacket.DecodeFeedback) error

DecodeFromBytes decodes the given bytes into this layer.

func (*RADIUS) LayerType ¶

func (radius *RADIUS) LayerType() gopacket.LayerType

LayerType returns LayerTypeRADIUS.

func (*RADIUS) Len ¶

func (radius *RADIUS) Len() (int, error)

Len returns the length of a RADIUS packet.

func (*RADIUS) NextLayerType ¶

func (radius *RADIUS) NextLayerType() gopacket.LayerType

NextLayerType returns the layer type contained by this DecodingLayer.

func (*RADIUS) Payload ¶

func (radius *RADIUS) Payload() []byte

Payload returns the EAP Type-Data for EAP-Message attributes.

func (*RADIUS) SerializeTo ¶

func (radius *RADIUS) SerializeTo(b gopacket.SerializeBuffer, opts gopacket.SerializeOptions) error

SerializeTo writes the serialized form of this layer into the SerializationBuffer, implementing gopacket.SerializableLayer. See the docs for gopacket.SerializableLayer for more info.

type RADIUSAttribute ¶

	Type   RADIUSAttributeType
	Length RADIUSAttributeLength
	Value  RADIUSAttributeValue
}

RADIUSAttribute represents attributes.

type RADIUSAttributeLength ¶

type RADIUSAttributeLength uint8

RADIUSAttributeType represents attribute length.

type RADIUSAttributeType ¶
