Member Function Documentation

char * usipp::IP::get_dst ( int resolv, char * buf, size_t buflen )

Ditto, destination-adress.

u_int32_t usipp::IP::get_dst ( )

Ditto, destination-adress.

u_int16_t usipp::IP::get_fragoff ( )

Get fragmentation offset.

u_int8_t usipp::IP::get_hlen ( )

Returns headerlen/4.

u_int16_t usipp::IP::get_id ( )

Get id-field.

iphdr usipp::IP::get_iphdr ( )

Return complete IP header. usefull for special ICMP packets

u_int8_t usipp::IP::get_proto ( )

Get protocol, TCP or such.

char * usipp::IP::get_src ( int resolv, char * buf, size_t buflen )

Get source-adress i human-readable-form. Resolve to an hostname, if resolv==1.

u_int32_t usipp::IP::get_src ( )

Get source-adress of packet, in network order.

u_int16_t usipp::IP::get_sum ( )

Get IP-header checksum

u_int8_t usipp::IP::get_tos ( )

Get Type Of Service.

u_int16_t usipp::IP::get_totlen ( )

Get total length of packet, including any data. Return len in host-order.

u_int8_t usipp::IP::get_vers ( )

returns IP-version. Should give 4 always.

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

Initialize a device for packet capturing Reimplemented from usipp::Layer2. Reimplemented in usipp::ICMP, usipp::TCP, and usipp::UDP.

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

assig-operator

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

Send a Packet. Reimplemented in usipp::ICMP, usipp::TCP, and usipp::UDP.

int usipp::IP::set_dst ( const char * )

Ditto, destination. Not needed if the destination given in the constructor is OK.

int usipp::IP::set_dst ( u_int32_t )

Ditto, destination.

int usipp::IP::set_hlen ( u_int8_t )

Set header-len in number of 32 bit words. 5 (5*4 = 20) in normal case. Contructor does this for you, so you should not use this.

int usipp::IP::set_id ( u_int16_t )

Set ID-field. Also not needed.

int usipp::IP::set_proto ( u_int8_t )

Set protocol. If you use TCP {} or such, you don't need to do it yourself.

int usipp::IP::set_src ( const char * ip_or_name )

Set source-adress.

int usipp::IP::set_src ( u_int32_t )

Set source-adress. Expects Network-ordered.

int usipp::IP::set_totlen ( u_int16_t )

Set total length of packet. Not needed.

int usipp::IP::set_ttl ( u_int8_t )

Set time-to-live field. Not needed.

int usipp::IP::set_vers ( u_int8_t )

Set version-field. Normally not needed.

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

Capture an packet from the net Reimplemented from usipp::Layer2. Reimplemented in usipp::ICMP, usipp::TCP, and usipp::UDP.
