TCP/IP protocol Learning (4) C # Socket-based Web Server --- static resource processing, A Web server is the host of a Web resource. It must process requests from a browser on the user side and specify the corresponding Web resource to be returned to the user. These resources not only include HTML files, JS scripts, and jpg images, it also includes dynamic content generated by software. To meet the above re

Use protocol analysis tools to learn TCP/IP I. Preface At present, the speed of network development is very fast, and more people are learning the network. People with a little knowledge about the network know that the TCP/IP protocol is the basis of the network and the language of the Internet, it can be said that the

This article is reproduced from: http://blog.sina.com.cn/s/blog_5ec353710101i892.html did a little tidying up. The TCP/IP reference model is a very basic and also very important basic framework, this document through a simple example, combined with a reference model to analyze the basic process of packet flow.The network environment is very simple, as shown, we now analyze the PC to access Web Server Web se

"When transmitting data, we can only use the (Transport Layer) TCP/IP protocol. However, without the application layer, we cannot identify the data content, to make the transmitted data meaningful, you must use the application layer protocol. There are many application layer protocols, such as HTTP, FTP, and telnet. You can also define the application layer protocol by yourself. Web uses HTTP as the applica

Some performance bottlenecks and Linux TCP/IP protocol stack settings, so specifically Google the Linux TCP/IP stack of the parameters of the meaning and configuration, recorded.If

SCO TCP/IP network management-tool IntroductionAfter the last six articles, we should introduce the TCP/IP management a lot. Next I will take the end and introduce some TCP/IP tools in UNIX, I hope my article will be helpful to yo

Overview This article discusses how to query the TCP/IP protocol stack of a host to collect valuable information. FirstFirst, I enumerated several "classic" operating system identification methods outside the stack fingerprint. And thenI described the "process status" of the stack fingerprint tool. Next, let the remote host leak itsSome techniques of information. Finally detailing my implementation (NMAP),

The Maximum Transmission unit (Maximum transmission Unit,MTU) refers to the maximum packet size (in bytes) that can be passed on a layer of a communication protocol. The network in the data link layer has a limit on the length of the data frame, the MTU value of different networks is different, the commonly used Ethernet is 1500 bytes.If the datagram size to be transmitted at the IP layer is larger than the MTU of the link layer, then the

The network seven layer is from the bottom up to the physical layer, the data link layer, the network layer, the transport layer, the conversation layer, the presentation layer and the application layer respectively.The physical layer, the data link layer and the network layer are often called media layers, which are the objects researched by network engineers.The transport layer, the session layer, the presentation layer, and the application layer are referred to as the host layer and are the c

Among the networks, we are most worried about security vulnerabilities. Most Internet users are still using IPv4 networks. In this version, the network protocol is based on the tcp ip protocol. What are the vulnerabilities in this protocol family? Currently, the tcp ip protocol is used on the Internet. The

TcpTCP is a connection-oriented communication protocol, the connection is established through three handshake, the communication is completed to remove the connection, because TCP is connection-oriented so can only be used for end-to-end communication.TCP provides a reliable data flow service, using "positive confirmation with retransmission" technology to achieve the reliability of transmission. TCP also u

pipe, which is composed of different water pipes of different thickness (different MTU). The maximum water volume of the pipe is determined by the finest water pipe in the middle. For upper-layer protocols at the network layer (here, the TCP/IP protocol family is used as an example), they do not care about the width of the "water pipe". They think this is a thing at the network layer. The Network Layer

ARP part IP ICMP UDP part TCP Section 1. UDP IntroductionUDP is a simple datagram-oriented transport layer protocol. Each output operation of a process generates a UDP datagram and assembles it into an IP datagram to be sent. This is different from the stream-oriented character protocol, such as TCP. The full data gen
