type Analyzer

type Analyzer struct {
	FragmentSize    uint16
	FragmentMaxSize uint32
	Fragments       map[uint16][]byte
	Debug           bool
	GoDump          bool
	HexDump         bool
	OpCodes         []*SEQOPCodeXML

Analyzer represents an analyzer parser

func New

func New() (*Analyzer, error)

New creates a new Analyzer

func (*Analyzer) Dump

func (a *Analyzer) Dump(data []byte) (output string)

Dump will either export information as Go type data or a hex dump

func (*Analyzer) PacketStep1

func (a *Analyzer) PacketStep1(psPacket gopacket.Packet) ([]*EQPacket, error)

PacketStep1 begins processing a packet step1: break down dst/src, figure out if compressed

type EQPacket

type EQPacket struct {
	OpCode        uint16
	OpCodeLabel   string
	SourceIP      net.IP
	ClientPort    string
	DestinationIP net.IP
	Data          []byte
	Timestamp     time.Time

EQPacket represents a completed EQ packet

func (*EQPacket) IsFromServer

func (packet *EQPacket) IsFromServer() bool

IsFromServer returns true if dstIP is a private ip address

func (*EQPacket) String

func (packet *EQPacket) String() string

type Fragment

type Fragment struct {
	CreateDate time.Time
	Data       []byte

Fragment is partial packets received

	XMLName xml.Name `xml:"seqopcodes"`
	Text    string   `xml:",chardata"`
	Opcodes []struct {
		Op      uint16
		Text    string `xml:",chardata"`
		ID      string `xml:"id,attr"`
		Name    string `xml:"name,attr"`
		Updated string `xml:"updated,attr"`
		Update  string `xml:"update,attr"`

			Text    string `xml:",chardata"`
			Payload struct {
				Text          string `xml:",chardata"`
				Dir           string `xml:"dir,attr"`
				Typename      string `xml:"typename,attr"`
				Sizechecktype string `xml:"sizechecktype,attr"`
			} `xml:"payload"`
		} `xml:"comment"`
		Payload []struct {
			Text          string `xml:",chardata"`
			Dir           string `xml:"dir,attr"`
			Typename      string `xml:"typename,attr"`
			Sizechecktype string `xml:"sizechecktype,attr"`
		} `xml:"payload"`
	} `xml:"opcode"`

SEQOPCodeXML is parsed from ShowEQ
