пытаюсь отправить пакет через raw socket вот типа пакет, но я не могу понять куда писать данные для отправки? данные это payload   iph->ip_hl = 5;   iph->ip_v = 4;   iph->ip_tos = 0;   iph->ip_len = sizeof (struct ip) + sizeof (struct tcphdr);   iph->ip_id = htonl (54321);    /* the value doesn't matter here */   iph->ip_off = 0;   iph->ip_ttl = 255;   iph->ip_p = 6;   iph->ip_sum = 0;        /* set it to 0 before computing the actual checksum later */   iph->ip_src.s_addr = inet_addr ("1.2.3.4");/* SYN's can be blindly spoofed */   iph->ip_dst.s_addr = sin.sin_addr.s_addr;   tcph->th_sport = htons (1234);    /* arbitrary port */   tcph->th_dport = htons (P);   tcph->th_seq = random ();/* in a SYN packet, the sequence is a random */   tcph->th_ack = 0;/* number, and the ack sequence is 0 in the 1st packet */   tcph->th_x2 = 0;   tcph->th_off = 0;        /* first and only tcp segment */   tcph->th_flags = TH_SYN;    /* initial connection request */   tcph->th_win = htonl (65535);    /* maximum allowed window size */   tcph->th_sum = 0;/* if you set a checksum to zero, your kernel's IP stack               should fill in the correct checksum during transmission */   tcph->th_urp = 0;
