Sending my own ARP packet using SharpPcap and Packet.Net

问题 I am trying unsuccessfully so far to send an ARP packet I have created with Packet.Net using SharpPcap. The problem is even though I send the packet using device.SendPacket it doesn't actually get sent, and I have no idea why. This is my code: ARPPacket arpPacket = new ARPPacket(ARPOperation.Request, PhysicalAddress.Parse("000000000000"), targetIpAddress, device.Interface.MacAddress, myIpAddress); EthernetPacket ethPacket = new EthernetPacket(device.Interface.MacAddress, PhysicalAddress.Parse

问题 I need small sniffer for my report so I went with C# and SharpPcap. packet = Packet.ParsePacket(rawCapture.LinkLayerType, rawCapture.Data); tcpPacket = TcpPacket.GetEncapsulated(packet); I have raw packet with all packet data. Then I get Packet out of it with some info such as source/destination/protocol/etc. After that I get tcp packet out of that. Now how do I get only actual packet data that software sent/received? 回答1: Was simple enough. packet.PayloadPacket.PayloadPacket.PayloadData 回答2:

问题 I just want to listen a network device, capture packets and write the packets to a dummy file. Also i need to filter packets while listening so ill only write packets which passes the filter. I need to do these on .net c#. These are my requirements. So which one should i use? High transfer rate and minimum packet loss is really important. Thanks for reading. 回答1: As the author of SharpPcap I can say that you'll be able to perform all of those operations with the library. Performance was a

问题 I use SharpPcap library for realise GOOSE protocol listener (EtherType = 0x88B8). It works well, but only if I run Wireshark in parallel, otherwise my program does not catch GOOSE packets. SharpPcap examples also don't capture GOOSE packets while Wireshark is not running. But SharpPcap library captures my broadcast UDP packets. 回答1: I had to open my SharpPCap device in promiscuous mode: winPcap.Open(SharpPcap.WinPcap.OpenFlags.Promiscuous | SharpPcap.WinPcap.OpenFlags.NoCaptureLocal,

问题 I am trying to get SharpPcap Statistics to work, but the OnPcapStatistics event never fires. Here's the code: SharpPcap Example 11: statistics Code project article: SharpPcap: Statistics Does anyone know why? 回答1: You just found a bug! WinPcapDevice was creating a new SendPacketArrivalEvent() instead of overriding it. Modified PcapDevice.SendPacketArrivalEvent() to be a virtual and WinPcapDevice.SendPacketArrivalEvent() to be an override and now the correct method is called. The issue was

In SharpPCap How do I find the IP Address of the Device?

由 徘徊边缘 提交于 2019-12-07 18:05:00
问题 I am using a WinPCapDevice and have already initialized it. I just want to be able to get the IP from that device and I cannot find anywhere how to extract the IP address of the Device. If there isnt a way to do it then is there another way to get the IP address of a WinPCapDevice so that I can check it against a list of IPAddresses? Here is the small chunk of code that I am talking about. IPHostEntry host; host = Dns.GetHostEntry(Dns.GetHostName()); foreach (IPAddress ip in host.AddressList)

问题 BACKGROUND : I now understand how to write a C# application that can monitor packets going in/out of the network card on the PC the application is running on. The approach I know relies on http://www.winpcap.org/ being already installed on the PC however, and then I use a C# wrapper such as http://pcapdotnet.codeplex.com/ or http://sourceforge.net/projects/sharppcap/ .
