使用SharpPcap和Packet.Net发送我自己的ARP数据包

Question

到目前为止，我尝试使用SharpPcap发送使用Packet.Net创建的ARP数据包，但没有成功。问题是，即使我使用device.SendPacket发送数据包，它实际上也不会被发送，我也不知道为什么。

这是我的代码：

ARPPacket arpPacket = new ARPPacket(ARPOperation.Request, PhysicalAddress.Parse("000000000000"), targetIpAddress, device.Interface.MacAddress, myIpAddress);
EthernetPacket ethPacket = new EthernetPacket(device.Interface.MacAddress, PhysicalAddress.Parse("FFFFFFFFFFFF"), EthernetPacketType.Arp);
ethPacket.PayloadPacket = arpPacket;
device.Open();
device.SendPacket(ethPacket);
device.Close();

顺便说一下，重要的是我发送自己的ARP包，而不是仅仅使用SharpPcap ARP类。

Answer 1

public static void ARP(IPAddress ipAddress , LivePcapDevice device)
{
if (ipAddress == null )
throw new Exception("ARP IP address Cannot be null");
var ethernetPacket = new PacketDotNet.EthernetPacket(device.Addresses[1].Addr.hardwareAddress, PhysicalAddress.Parse("FF-FF-FF-FF-FF-FF"), PacketDotNet.EthernetPacketType.Arp);

var arpPacket = new PacketDotNet.ARPPacket(PacketDotNet.ARPOperation.Request, PhysicalAddress.Parse("00-00-00-00-00-00"), ipAddress , device.Addresses[1].Addr.hardwareAddress, device.Addresses[0].Addr.ipAddress );
ethernetPacket.PayloadPacket = arpPacket;

device.SendPacket(ethernetPacket);
}

查看this code，不涉及以太网络数据包

ARPPacket arpPacket = new ARPPacket(ARPOperation.Request, PhysicalAddress.Parse("000000000000"), targetIpAddress, device.Interface.MacAddress, myIpAddress);
arpPacket.ARPTargetProtoAddress = destIP;
arpPacket.DestinationHwAddress = PhysicalAddress.Parse("FF-FF-FF-FF-FF-FF");
device.Open();
device.SendPacket(arpPacket);
device.Close();
