在 C# 上使用 SharpPcap 进行 IP 地址欺骗

发布于 2024-09-02 03:40:30 字数 411 浏览 9 评论 0原文

我将使用 SharpPcap 框架来制作我的欺骗程序，因此我需要在源地址字段中使用另一个 IP 地址编辑数据包的机器 IP 地址。

我在 SharpPcap 项目上找到了一些示例，但是如何编辑或更改发送数据包的源地址字段？

这是发送随机数据包的示例代码：

byte[] bytes = GetRandomPacket();

private static byte[] GetRandomPacket()
{
    byte[] packet = new byte[200];
    Random rand = new Random();
    rand.NextBytes( packet );
    return packet;
}

- device.SendPacket( 字节 );

原文

I will use SharpPcap framework to make my spoofing program, so I need to edit my machine's IP address of the packet with another IP address on the source address field.

I found some example on SharpPcap project, but how can I edit or change the source address field of sending packet?

Here is the sample code for sending random packets:

byte[] bytes = GetRandomPacket();

private static byte[] GetRandomPacket()
{
    byte[] packet = new byte[200];
    Random rand = new Random();
    rand.NextBytes( packet );
    return packet;
}

-
device.SendPacket( bytes );

请尝试使用 Pcap.Net。

以下是如何在 Pcap.Net 中构建具有特定源地址和目标地址以及自定义负载的简单 IPv4 数据包：

Packet packet =
    PacketBuilder.Build(DateTime.Now,
                        new EthernetLayer
                            {
                                Source = new MacAddress("11:22:33:44:55:66"),
                                Destination = new MacAddress("11:22:33:44:55:67"),
                            },
                        new IpV4Layer
                            {
                                Source = new IpV4Address("1.2.3.4"),
                                Destination = new IpV4Address("1.2.3.5"),
                                Ttl = 64,
                                Identification = 100,
                            },
                        new PayloadLayer
                            {
                                Data = new Datagram(new byte[] {1, 2, 3, 4})
                            });

Try Pcap.Net instead.

Here is how you build a simple IPv4 packet with specific source and destination addresses and a custom payload in Pcap.Net:

Packet packet =
    PacketBuilder.Build(DateTime.Now,
                        new EthernetLayer
                            {
                                Source = new MacAddress("11:22:33:44:55:66"),
                                Destination = new MacAddress("11:22:33:44:55:67"),
                            },
                        new IpV4Layer
                            {
                                Source = new IpV4Address("1.2.3.4"),
                                Destination = new IpV4Address("1.2.3.5"),
                                Ttl = 64,
                                Identification = 100,
                            },
                        new PayloadLayer
                            {
                                Data = new Datagram(new byte[] {1, 2, 3, 4})
                            });
