Example #1

File: module_tcp_synscan.c Project: prelongs/zmapscan

void synscan_print_packet(FILE *fp, void* packet)
{
	struct ether_header *ethh = (struct ether_header *) packet;
	struct ip *iph = (struct ip *) &ethh[1];
	struct tcphdr *tcph = (struct tcphdr *) &iph[1];
	fprintf(fp, "tcp { source: %u | dest: %u | seq: %u | checksum: %u }\n",
			ntohs(tcph->th_sport),
			ntohs(tcph->th_dport),
			ntohl(tcph->th_seq),
			ntohl(tcph->th_sum));
	fprintf_ip_header(fp, iph);
