1. Obtain the NIC device name. The name is not shown in Ipconfig, but it needs to call the function Pcap_findalldevs.The 2.WINPCAP captures the dial-up network data such as 3G network cards and needs to install netmon,http://www.microsoft.com/en-us/download/details.aspx?id=4865.3.winpcap only supports Visual C + + by default.4.winpcap to Dial-Up Networking PPP on

WinPcap is an open source library based on the Win32 platform for capturing and analyzing network packets.Most Web applications access the network through widely used operating system components, such as sockets. This is a simple implementation because the operating system has properly handled the underlying implementation details (such as protocol processing, encapsulation of packets, etc.) and provides a familiar interface to read and write files.So

The focus of this time is on the parsing of the data. Specific WinPcap operation, because the Official handbook has been very good and powerful, I will not nonsense. Just leave a link here, you can see it on your own. Chinese Manual: Http://www.coffeecat.net.cn/winpcap/html/index.html Now, let's say we've crawled into a packet. Packet parsing also involves a large number of decimal points. For convenien

Well, before I said so much, finally arrived, we can fencing the time.Before programming the ARP protocol, we must be able to control the network adapter (NIC), this part is the driver! "We're going to write the NIC driver?" "Yes, but at least we don't need it at this stage. There are well-written drivers and development kits on the network that we can use to get them. I'm using WinPcap's driver and development package, so we'll start by installing and building our programming environment:1, dow

* p,struct pcap_pkthdr* h)Returns the next available packet and returns a pointer to the part of the data packet that the U_char points to. If an error occurs or the active packet is not read to the packet (for example: the packet cannot be discarded through the packet filter, or the timeout expires before any packets arrive on the platform that supports the read timeout), Alternatively, the file descriptor for the packet capture device is in nonblocking (non-blocking) mode and no packet can be
