Class KrakenDnsProtocolHandler

java.lang.Object

at.jku.fim.rubanetra.protocol.KrakenBaseProtocol

at.jku.fim.rubanetra.protocol.handler.KrakenDnsProtocolHandler

All Implemented Interfaces:

BaseProtocol, org.krakenapps.pcap.decoder.tcp.TcpProcessor, org.krakenapps.pcap.decoder.udp.UdpProcessor

public class KrakenDnsProtocolHandler
extends KrakenBaseProtocol
implements org.krakenapps.pcap.decoder.udp.UdpProcessor, org.krakenapps.pcap.decoder.tcp.TcpProcessor

This class does not utilize a Kraken decoder directly, instead it represents the decoding processors as an implementation of UdpProcessor and TcpProcessor. The org.xbill.dns Java library (see Message) is used as primary payload decoder. Several modifications were required to process both, UDP- and TCP-based payloads, therefore this implementation is still considered experimental and may (silently) fail to decode valid DNS messages.

Method Detail

getProtocolId

public ProtocolId getProtocolId()

Description copied from interface: BaseProtocol

An arbitrary identifier for the protocol(s) this decoder should be able to parse and decode. This identifier must be unique and may not be reused multiple times inside this framework for multiple decoders, even if the same protocol can be decoded by multiple implementations.

Specified by:

getProtocolId in interface BaseProtocol

Returns:

a unique identifier used to represent the decoding capabilities of this decoder
