mvc 4 を使用して asp.net プログラムを実行しました。iis サーバーに localhost としてデプロイしました。HTTP パケットを追跡したいので、SharpPcap を使用しました。
これが完全なコードです...
namespace CaseStudy
{
class Program
{
static void Main(string[] args)
{
var parmenter = SharpPcap.CaptureDeviceList.Instance;
/*If no device exists, print error */
if (parmenter.Count < 1)
{
Console.WriteLine("No device found on this machine");
return;
}
int i = 0;
Console.WriteLine("Choose Your Devices :");
Console.WriteLine("----------------------");
foreach (PcapDevice dev in parmenter)
{
/* Device Description */
Console.WriteLine("{0}] {1} [MAC:{2}]", i, dev.Interface.FriendlyName, dev.Interface.MacAddress);
i++;
}
Console.WriteLine("----------------------");
//Extract a device from the list
int deviceIndex = -1;
do
{
Console.WriteLine("Enter Your Choice :");
deviceIndex = int.Parse(Console.ReadLine());
} while (!(deviceIndex < parmenter.Count && deviceIndex >= -1));
ICaptureDevice device = parmenter[deviceIndex];
//Register our handler function to the 'packet arrival' event
//device.PcapOnPacketArrival += new SharpPcap.PacketArrivalEventHandler();
device.OnPacketArrival += new SharpPcap.PacketArrivalEventHandler(device_OnPacketArrival);
//Open the device for capturing
//true -- means promiscuous mode
//1000 -- means a read wait of 1000ms
device.Open(DeviceMode.Promiscuous, 1000);
device.Filter = "ip and tcp";
Console.WriteLine("-- Listenning on {0}, hit 'Enter' to stop...", device.MacAddress);
//Start the capturing process
device.StartCapture();
//Wait for 'Enter' from the user.
Console.ReadLine();
//Stop the capturing process
device.StopCapture();
//Close the capturing device
device.Close();
}
private static void device_OnPacketArrival(object sender, CaptureEventArgs e)
{
DateTime time = e.Packet.Timeval.Date;
int len = e.Packet.Data.Length;
byte[] data = e.Packet.Data;
//var packet = TcpPacket.ParsePacket(e.Packet.LinkLayerType, e.Packet.Data);
//Console.WriteLine(e.Packet.LinkLayerType.ToString());
Packet pack = Packet.ParsePacket(e.Packet.LinkLayerType, e.Packet.Data);
if (pack is PacketDotNet.EthernetPacket)
{
var eth = pack.Extract(typeof(EthernetPacket)) as EthernetPacket;
if (len > 100)
{
Console.WriteLine("ETHERNET/INTERNET/HTTP PACKET");
//Console.WriteLine(HttpServerUtility.UrlTokenEncode(eth.Bytes));
Console.WriteLine("{0}-{1}" , eth.DestinationHwAddress, eth.SourceHwAddress);
//Console.WriteLine(eth.PayloadPacket.PayloadPacket.PrintHex());
Console.WriteLine(System.Text.Encoding.UTF8.GetString(eth.Bytes));
}
}
if (pack is PacketDotNet.TcpPacket) {
var tcp = pack.Extract (typeof(TcpPacket)) as TcpPacket;
if (len > 100)
{
//Console.WriteLine("[{0}:{1}:{2}:{3}][{4}][{5}]",
//time.Hour, time.Minute, time.Second, time.Millisecond,
//len, Stringfy.RawPacketToHex(data));
Console.WriteLine("TCP PACKET");
Console.WriteLine(tcp.PrintHex());
//Console.WriteLine(arp.SenderHardwareAddress);
}
}
if (pack is PacketDotNet.InternetPacket)
{
var inet = pack.Extract(typeof(InternetPacket)) as InternetPacket;
if (len > 100)
{
//Console.WriteLine("[{0}:{1}:{2}:{3}][{4}][{5}]",
//time.Hour, time.Minute, time.Second, time.Millisecond,
//len, Stringfy.RawPacketToHex(data));
Console.WriteLine("INTERNET PACKET");
Console.WriteLine(inet.PrintHex());
//Console.WriteLine(arp.SenderHardwareAddress);
}
}
if (pack is PacketDotNet.IpPacket)
{
var ip = pack.Extract(typeof(IpPacket)) as IpPacket;
if (len > 100)
{
//Console.WriteLine("[{0}:{1}:{2}:{3}][{4}][{5}]",
//time.Hour, time.Minute, time.Second, time.Millisecond,
//len, Stringfy.RawPacketToHex(data));
Console.WriteLine("IP PACKET");
Console.WriteLine(ip.PrintHex());
//Console.WriteLine(arp.SenderHardwareAddress);
}
}
}
}
}
Google、stackoverflow、facebook などのリモート サーバーの http パケットをキャプチャするこのコードは、私のシステムと通信します。
ただし、システムをローカルホストとしてのみ使用してパケットを追跡したい。
使用して
誰でも助けることができますか？お願いします...
