1, Foreword Through the previous study, we are familiar with capturing packets from the network card. Now we will learn how to process packets. WinPcap provides us with many API s to save packets flowing through the network to a heap file and read the contents of the heap. The format of this file is very simple, but it contains the binary cont ...

Java Programming Network Programming TCP Programming Complete the development of TCP programs using Socket s Use this class to easily establish a reliable, two-way, continuous, point-to-point communication connection In Socket development, the server side uses ServerSocket to wait for the client to connect. For Java network programs, each cl ...

1, PXE 1. Principle and concept: The pre boot execution environment (PXE), also known as the pre execution environment, provides a mechanism for starting a computer using a Network Interface. This mechanism allows the computer to start without relying on the local data storage device (hard disk) or the locally installed operating system. Ser ...

Use TCP to transmit data, write the program of client and server, and realize the real-time communication between the two programs. In each program, the function of sending and receiving data in real time is realized. io interface of client Server side io interface io demo The program takes ...

1. IP address Computers in the network use IP addresses for unique identification. There are two types of IP addresses: IPv4 and IPv6. It is generally expressed in decimal system, such as ipv6.168.1, but not in decimal system. How to view IP address related information: Under Windows system, open cmd, enter the command ipconfig, and press en ...
