如何在C#中广播ARP数据包

发布于 2024-09-09 21:05:59 字数 105 浏览 7 评论 0原文

我想通过C#发送ARP数据包。我不知道如何在 C# 中形成 ARP 数据包（格式）。有人可以帮忙吗？加上如何发送arp数据包或广播它。

任何示例代码都受到高度赞赏。提前致谢。

这是您可能感兴趣的库：http://www.beesync。 com/packetx/docs/html/index.html

以及 send.cs 文件中的片段。

// Get adapter hardware address and IP address
  Adapter oAdapter = (Adapter)oPktX.Adapter;
  string sHWAddr = oAdapter.HWAddress;
  string sIPAddr = oAdapter.NetIP;
  string sIPMask = oAdapter.NetMask;
  Console.WriteLine("MAC Addr = " + sHWAddr);
  Console.WriteLine("IP  Addr = " + sIPAddr);

  // Send ARP request for this IP address
  string sIPReso = "11.12.13.14";
  char [] aDelimiter = {'.'};
  string[] aIPReso = sIPReso.Split(aDelimiter, 4);
  string[] aIPAddr = sIPAddr.Split(aDelimiter, 4);

  // Build ARP packet
  Object[] oPacket = new Object[] { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF,
    Convert.ToByte("0x" + sHWAddr.Substring(0,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(2,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(4,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(6,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(8,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(10,2), 16),
    0x08, 0x06, 0x00, 0x01,
    0x08, 0x00, 0x06, 0x04, 0x00, 0x01,
    Convert.ToByte("0x" + sHWAddr.Substring(0,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(2,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(4,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(6,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(8,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(10,2), 16),
    Convert.ToByte(aIPAddr[0], 10),
    Convert.ToByte(aIPAddr[1], 10),
    Convert.ToByte(aIPAddr[2], 10),
    Convert.ToByte(aIPAddr[3], 10),
    0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
    Convert.ToByte(aIPReso[0], 10),
    Convert.ToByte(aIPReso[1], 10),
    Convert.ToByte(aIPReso[2], 10),
    Convert.ToByte(aIPReso[3], 10),
    0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
    0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
    0x00, 0x00, 0x00, 0x00, 0x00, 0x00};

  // Send 100 ARP requests      
  oAdapter.SendPacket(oPacket, 100);

编辑：

最好的方法是使用 WinPCap 库，现在它们正式以 C 语言而不是 C# 语言提供，但如果您已经安装了 winpcap，则可以导入 wpcap.ddl，这是您可能想要查看的其他一些资源：

Here is a library you might be interested in: http://www.beesync.com/packetx/docs/html/index.html

And a Snippit from the send.cs File.

// Get adapter hardware address and IP address
  Adapter oAdapter = (Adapter)oPktX.Adapter;
  string sHWAddr = oAdapter.HWAddress;
  string sIPAddr = oAdapter.NetIP;
  string sIPMask = oAdapter.NetMask;
  Console.WriteLine("MAC Addr = " + sHWAddr);
  Console.WriteLine("IP  Addr = " + sIPAddr);

  // Send ARP request for this IP address
  string sIPReso = "11.12.13.14";
  char [] aDelimiter = {'.'};
  string[] aIPReso = sIPReso.Split(aDelimiter, 4);
  string[] aIPAddr = sIPAddr.Split(aDelimiter, 4);

  // Build ARP packet
  Object[] oPacket = new Object[] { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF,
    Convert.ToByte("0x" + sHWAddr.Substring(0,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(2,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(4,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(6,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(8,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(10,2), 16),
    0x08, 0x06, 0x00, 0x01,
    0x08, 0x00, 0x06, 0x04, 0x00, 0x01,
    Convert.ToByte("0x" + sHWAddr.Substring(0,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(2,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(4,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(6,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(8,2), 16),
    Convert.ToByte("0x" + sHWAddr.Substring(10,2), 16),
    Convert.ToByte(aIPAddr[0], 10),
    Convert.ToByte(aIPAddr[1], 10),
    Convert.ToByte(aIPAddr[2], 10),
    Convert.ToByte(aIPAddr[3], 10),
    0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
    Convert.ToByte(aIPReso[0], 10),
    Convert.ToByte(aIPReso[1], 10),
    Convert.ToByte(aIPReso[2], 10),
    Convert.ToByte(aIPReso[3], 10),
    0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
    0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
    0x00, 0x00, 0x00, 0x00, 0x00, 0x00};

  // Send 100 ARP requests      
  oAdapter.SendPacket(oPacket, 100);

Edit:

The best way to do this is by using the WinPCap Libraries now they officially come in C and not C# but you can import the wpcap.ddl if you have installed winpcap, Heres some other resources that you may want view:
