completely replaces B. What follows is like an intruder's mood. In this sense, any machine's Sniffer can be used to track all communication data ). As mentioned above, I still only have an understanding of the concept and principle and a summary of these aspects. It is not enough to achieve the level of practice. Network Packet Capture is now available, but it is still early to talk about protocol analysis. It is difficult to even construct RAW Socke

Let's look at what happens when we enter http://www.mycompany.com:8080/mydir/index.htmlin the browser, behind the scenes.First HTTP is an application layer of protocol, in this layer of protocol, is just a communication specification, that is, because the two sides to communicate, we have to agree to a specification beforehand.1. Connection when we enter such a request, first to establish a socket connection, because the socket is established through

1 What's all this? Since it is a network transmission, involving several systems, the first thing to consider is how to accurately navigate to one or several hosts on the network, and the other is how to reliably and efficiently of data transfer. The TCP/IP protocol will be used here. 1.1 TCP/

In this article, we will share a php program that can ping multiple ip addresses at the same time and then compare and find the fastest ip address in the network. This program is used to find the proxy ip address, but it is an artifact. In this article, we will share a php program that can ping multiple

This protocol can provide connection-oriented, reliable, point-to-point communication.The UDP full name is the User Datagram Protocol, which can provide non-connected unreliable point-to-multipoint communication.With TCP or UDP, it depends on which aspect your program focuses on, whether it is reliable (TCP) or Fast (UDP).The process of establi

During this period, I read volume 1 in "TCP/IP details". The biggest feature of this book is that it uses the tcpdump program to capture various network packages, this gives us a definite understanding of the protocols and Algorithms in each layer of the network. It is the protocol discussed in this book and its hierar
