For this I created several functions: int initiate_TXRX_variables(void) { struct hostent * hp; hp = gethostbyname("localhost"); if(hp == NULL) return INVALID_SOCKET; memset(&sa_udp_in, 0, sizeof(sa_udp_in)); memset(&sa_tcp_in, 0, sizeof(sa_tcp_in)); memset(&sa_udp_out, 0, sizeof(sa_udp_out)); memset(&sa_tcp_in, 0, sizeof(sa_tcp_in)); memcpy((char *)&sa_udp_in.sin_addr, hp->h_addr, hp->h_length); memcpy((char *)&sa_tcp_in.sin_addr, hp->h_addr, hp->h_length); memcpy((char *)&sa_udp_out.sin_addr, hp->h_addr, hp->h_length); memcpy((char *)&sa_tcp_out.sin_addr, hp->h_addr, hp->h_length); sa_udp_in.sin_family = hp->h_addrtype; sa_tcp_in.sin_family = hp->h_addrtype; sa_udp_out.sin_family = hp->h_addrtype; sa_tcp_out.sin_family = hp->h_addrtype; sa_udp_in.sin_port = htons((u_short)PORTNUM_UDP_IN); sa_tcp_in.sin_port = htons((u_short)PORTNUM_TCP_IN); sa_udp_out.sin_port = htons((u_short)PORTNUM_UDP_OUT); sa_tcp_out.sin_port = htons((u_short)PORTNUM_TCP_OUT); return 1; } int ultra_spam_network_udp(void) { struct hostent *hp, *local; hp = gethostbyname("192.168.70.0"); hp = gethostbyname("255.255.255.255"); local = gethostbyname("localhost"); memcpy((char *)&sa_udp_out.sin_addr,hp->h_addr, hp->h_length); //set_ip_udp_out(htonl(ntohl(sa_udp_out.sin_addr.s_addr) - 1)); InetPton(AF_INET, "192.168.30.0", &(sa_udp_out.sin_addr)); char str[] = "Hello"; char ipstr[256]; for(int i = 0; i < 256; i++) { std::cout << "Local: " << retLocalIP() << " and current IP: " << /*inet_ntoa(sa_udp_out.sin_addr)*/InetNtop(AF_INET, &(sa_udp_out.sin_addr), ipstr, 256) << " with counter: " << i << '\n'; sendto(UDP_OUT, str, sizeof(str), 0, (struct sockaddr*)&sa_udp_out, sizeof(sa_udp_out)); sa_udp_out.sin_addr.s_addr = htonl(ntohl(sa_udp_out.sin_addr.s_addr)+1); }; //sendto(UDP_OUT, str, sizeof(str), 0, (struct sockaddr*)&sa_udp_out, sizeof(sa_udp_out)); return 0; } int/*char **/ listen_udp_debug(void) { struct
