Constructor & Destructor Documentation

usipp::TCP::TCP ( const char * )

Copy-constructor

Member Function Documentation

u_int32_t usipp::TCP::get_ack ( )

Get acknowlegde-number of packet.

u_int16_t usipp::TCP::get_dstport ( )

Get destination-port in host-order

u_int8_t usipp::TCP::get_flags ( )

Get TCP-flags. Can be either of TH_SYN TH_ACK TH_FIN TH_RST TH_PUSH TH_URG or any combination of these (althought common combinations are SYN|ACK or similar)

u_int8_t usipp::TCP::get_off ( )

Get TCP-data offset, sometimes called TCP-header-length. Should be 20 in most cases.

u_int32_t usipp::TCP::get_seq ( )

Get sequencenumber of packet.

u_int16_t usipp::TCP::get_srcport ( )

Get sourceport of packet, in host-order.

tcphdr usipp::TCP::get_tcphdr ( )

Return complete TCP header. Usefull for some kinds of ICMP messages

int usipp::TCP::get_tcpopt ( char * )

Fill buffer with 20 bytes, return the length of option-field.

int usipp::TCP::init_device ( char * dev, int promisc, size_t snaplen ) [virtual]

Just sets filter to TCP and calls Datalink::initdevice() Reimplemented from usipp::IP.

TCP & usipp::TCP::operator= ( const TCP & )

Assign-operator

int usipp::TCP::reset_tcpopt ( )

Clear header from all options

int usipp::TCP::sendpack ( char * pay_string ) [virtual]

Send a string. Reimplemented from usipp::IP.

int usipp::TCP::sendpack ( void * payload, size_t paylen ) [virtual]

Send a packet. Reimplemented from usipp::IP.

int usipp::TCP::set_dstport ( u_int16_t )

Set destination-port

int usipp::TCP::set_srcport ( u_int16_t )

Set source-port

int usipp::TCP::set_tcpopt ( char kind, unsigned char len, union tcp_options t )

Set a TCP-option of kind

int usipp::TCP::set_tcpsum ( u_int16_t )

Set TCP-checksum. Doing these will prevent sendpack() from doing this for you. It's not recommented that you do so, coz the sum will almost be weak.

int usipp::TCP::sniffpack ( void * buf, size_t buflen ) [virtual]

Capture a packet from the net. Reimplemented from usipp::IP.
