tcp ip ports and protocols

protocol used by this file transfer process is called the FTP protocol. File transfer in FTP establishes two TCP connections, respectively, to the control connection to use when sending a transmission request and to the data connection that is used when the data is actually transferred. Remote login (telnet and SSH) is a feature that logs on to a remote computer and enables programs on that computer to run. Remote logins commonly used telnet and ssh

layer:Routers, layer three switches Transport Layer:Four-layer switch, also has a router working on layer four T the CP (transmission Control Protocol) and UDP (User Datagram Protocol) protocols belong to the Transport layer protocol. TCP provides reliable data transmission in IP environment, and it provides services including data transfer, reliability, effecti

more powerful (complex) filter. It allows you to quickly and accurately locate the required records in a log file. 1. Capture Filter The syntax for capturing filters is the same as other software developed using LIPCAP (Linux) or WinPcap (Windows) libraries, such as the famous tcpdump. The capture filter must be set before starting the capture, which is different from the display filter.The steps to set up a capture filter are:-Select Capture-> options.-Fill in the "Capture Filter" bar or click

The main reason is that you are not familiar with network protocols and are not clear about some concepts. Later, I spent some time learning about these network protocols. Now I have a preliminary

Introduction to TCP/IP and other network protocols 1. TCP/IP is a communication protocol for the Internet. Computer Communication Protocols are descriptions of the rules that computers must comply with in order to communicate with

The common understanding of TCP/IP network protocols was developed some time ago. network programming was involved and the development process was smooth. However, after the task was completed, I always felt a bit confused. The main reason is that you are not familiar with network protocols and are not clear about some

Q: What are the NetBEUI and IPX/SPX TCP/IP protocols ?? In particular, the first two are sometimes installed, and sometimes they are not installed. Why ?? What are their differences and uniqueness? When must I install it? A: A lot of netizens asked this question. I have consulted and integrated the relevant information here to give you a detailed explanation. The

This section briefly introduces the internal structure of TCP/IP and lays the foundation for discussing Internet-related security issues. TCP/IP protocol groups are popular in part because they can be used on a variety of channels and underlying protocols (such as T1 and X.2

We know that the tcp ip protocol stack includes many protocols. So let's take a look at the functions and functions of the protocols here. Now let's make an inventory check to help you summarize it and hope it will help you. 1. bsd tcp i
