Hi I try to sending flooding raw IP packets to the same destanation IP address. I use libnet to send raw ip packet, but I get a ARP packet sent before every my paket even the destination is same IP address I think that only one arp is enough to get the gateway MAC address. and I don't like to put a gateway Mac address in the arguments. How to resolve this problem? regards john - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
