packet dll

Under Linux, when we need to crawl network packet analysis, we usually use the Tcpdump crawl Network raw packet to a file, and then download it locally using the Wireshark Interface Network analysis tool for network packet analysis.Only recently found that the original Wireshark also provided with the Linux command line tool-tshark. Tshark not only has the functi

Static calls in C # C++dll and C # in dynamic call C++dllIn recent projects, involving the project source code security issues, because the code is written in C #, easy to be anti-compilation, so decided to extract the core algorithm is written in C + +, C + + so far seems not to be very good anti-compilation, of course, if you are an anti-assembly master, it may be possible to decompile. In this way, it involves invoking C # managed code with C + + u

Introduction to VC ++ dynamic link library (DLL) Non-MFC DLL 4.1 A simple DLL Section 2nd describes how to provide the add function interface using the static Link Library. Next we will look at how to use the dynamic link library to implement the add function with the same function. 6. Create a Win32 Dynamic-Link Library Project dllTest in VC ++ (Click here to do

Application layer packet capture solution and implementation Author: Fang Introduction Packet Capture needs generally come from filtering, conversion protocol, and packet capture analysis.Filters have many applications, typically packet filter firewall.The application of the conversion protocol is limited to some

First, a sample from a Shehiren teacher's book is referenced:Host H1 the process of sending packets to H2:First, with the subnet mask in the subnet:255.255.255.128 and target host H2 IP address:128.30.33.128 and get network number: 128.30.33.128. Obviously this does not match the network number of Subnet 1:128.30.33.0.The datagram is then forwarded by the default route R1 Subnet 1. At this point, R1 will look for its own routing table. Think of the host address and subnet mask of the H2, and whe

The title of the article is a bit around the mouth, like the execution of a command pipe, oh, because the server Setup problem can not upload too large compression package, this compression package can not continue to pass the breakpoint, all can only cut, in Windows under the use of software can be easily done, then in Linux how to solve it, It takes only two commands to handle it easily:Let's see the first command:Cat Jordan_shoes.tar.gz|split-b 100m–jordan_shoes.tar.gz.Explain:The-jordan_shoe

Sanniusignal is a completely free DLL Based on asynchronous socket. It encapsulates client, server, and UDP. With this DLL, you do not need to worry about heartbeat. Stick the package.Group packages, sending files, and other complex tasks. You only need a few simple steps to implement a powerful communication system. It can help you feel the happiest thing and hope you canFind out the deficiencies in the

The Non-MFC DLLs are explained in the previous section, and this section describes how to create an MFC rule DLL and how to use the MFC rule DLLs.　　I. Overview of MFC Rules DLLsThe concept of the MFC rules DLL is embodied in two ways:　　(1) It is MFC's"is MFC" means that MFC can be used inside this DLL;　　(2) It's a rule."is regular" means that it differs from the

frame, which can be divided into three steps: Open the WINPCAP device (handle/descriptor?). ), manually construct an underlying packet, send! The whole process has no extra action and is very simple. So how is WinPcap implemented?The image on the left is an architecture diagram from WinPcap Official document, WinPcap is a NPF (netgroup Packet filter, network packet
