In layered architectures, each lower layer * encapsulates data from its upper layer - that is it * treats the data from its upper layer as payload and prepends an own header to the packet, * which - again - is treated as the payload for the layer below. The figure below is an * example for how such a data frame is composed out of packets, e.g. when sending a mail. * * <pre> * | User Data | == Mail Data * | SMTP Header | User Data | == SMTP * | TCP Header | SMTP Header | User Data | == TCP * | IP Header | TCP Header | SMTP Header | User Data | == IP * | MAC Header | IP Header | TCP Header | SMTP Header | User Data | == MAC * * </pre> * @@ -448,98 +451,121 @@ class OARPPacket : public QObject Q_OBJECT public: OARPPacket( const unsigned char*, const struct myarphdr*, QObject* parent = 0 ); virtual ~OARPPacket(); QHostAddress senderIPV4Address() const; OMacAddress senderMacAddress() const; QHostAddress targetIPV4Address() const; OMacAddress targetMacAddress() const; //int type() const; QString type() const; private: const struct myarphdr* _arphdr; }; /*====================================================================================== * OUDPPacket *======================================================================================*/ class OUDPPacket : public QObject { Q_OBJECT public: OUDPPacket( const unsigned char*, const struct udphdr*, QObject* parent = 0 ); virtual ~OUDPPacket(); int fromPort() const; int toPort() const; + int length() const; + int checksum() const; private: const struct udphdr* _udphdr; }; /*====================================================================================== + * ODHCPPacket + *======================================================================================*/ + +class ODHCPPacket : public QObject +{ + Q_OBJECT + + public: + ODHCPPacket( const unsigned char*, const struct dhcp_packet*, QObject* parent = 0 ); + virtual ~ODHCPPacket(); + + private: + const struct dhcp_packet* _dhcphdr; +}; + +/*====================================================================================== * OTCPPacket *======================================================================================*/ class OTCPPacket : public QObject { Q_OBJECT public: OTCPPacket( const unsigned char*, const struct tcphdr*, QObject* parent = 0 ); virtual ~OTCPPacket(); int fromPort() const; int toPort() const; + int seq() const; + int ack() const; + int window() const; + int checksum() const; private: const struct tcphdr* _tcphdr; }; /*====================================================================================== * OPacketCapturer *======================================================================================*/ /** * @brief A class based wrapper for network packet capturing. * * This class is the base of a high-level interface to the well known packet capturing - * library libpcap. ... + * library libpcap. + * @see http://tcpdump.org */ class OPacketCapturer : public QObject { Q_OBJECT public: /** * Constructor. */ OPacketCapturer( QObject* parent = 0, const char* name = 0 ); /** * Destructor. */ ~OPacketCapturer(); /** * Set the packet capturer to use blocking or non-blocking IO.
