Often forget this thing. So summarize this thing and feel the agreement. FTP connection mode Control connection: Standard port, for sending FTP command information Data connection: Standard port, for uploading and downloading data Type of data connection establishment: Active mode: the server initiates a connection from Port 20 actively to the client Passive mode: The server is passively waiting f

FTP active and passive working mode-Linux Enterprise Application-Linux server application information. The following is a detailed description. Article from: http://linux.net527.cn/fuwuqiyingyong/Ftpfuwuqi/38774.html What is PASV mode (passive mode transfer )? How does he work? FTP connections generally have two connections: one is the client and the server transmission command, and the other is the data

In the use of FTP, often encountered after the FTP link file list error situation, just because the FTP mode is not correct, how to set the working mode of FTP, what is active mode, what is passive mode, active mode and passive mode what is the difference, Today, we collected relevant information and the methods of setting up the working mode of the common FTP software: One, what is PASV and Port way (1) po

Article Title: FTP active mode and passive mode. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. The FTP protocol can work in two ways: PORT and PASV, that is, active and passive. The active connection process is that the client sends a connection request to the ftp po

"Natural selection, survival of the fittest" is the law of evolution of nature, but also applicable to the replacement of products, innovation means change, which means the elimination. Recalling the development process of the switch, passive wireless remote control switch will replace the traditional switch, into households.First, the birth of the switchSince Edison invented the electric light, people have begun to break through the darkness of the o

First, we recommend that you replace the widely used concepts of "active errors" and "passive errors" with "active errors" and "passive errors ". 1. Active error site Once an error is detected, it immediately sends an error identifier "actively. The so-called "error mark" is itself a "wrong bit sequence" (six consecutive dominant bits, does not meet the "up to five consecutive same-sex bits" requirement of

Passive Scheduling Based on scheduling Timing Analysis (System Call return) Analysis based on kernel version 2.6.12.6 Under what circumstances will scheduling be triggered? Linux Process Scheduling mainly includes active scheduling and passive scheduling. ◆ Active Scheduling Active scheduling means that the process itself lacks the resources requested, and displays the call to schedule to let out the proces

I think Program There are two types of employees: "active programmers" and "passive programmers ". "Active programmers" can select their own development methods, development languages and frameworks, and "passive programmers" passively accept the company's specified languages and development methods. In real life, such classification is not absolute. A programmer may assume different roles at different tim

his own interests will be the winner in the end. Sometimes it's not that each other wants to hit you, but you find a fight. This is a very essential thing, and I have been calling the question, is that the music industry is too passive. The music industry has made so much money, but it has not developed its own technology, especially the media to develop music. I remember the first CD format developed by Philips, the music passively into a "plastic

Active and passive references to classes in Java, and java references This article focuses on active and passive references of classes in Java. Active referenceHere, we will introduce five scenarios for active reference. 1. When the four bytecode commands "new", "getstatic", "putstatic", and "invokestatic" are executed, the class will be initialized if it is not initialized, create an object, read or set st

A network testing team of Siemens Germany, supported by the European Union, recently announced that they have successfully tested the passive optical fiber network.

Two modes of operation for the FTP service: port (Active mode), connection process: The client sends a connection request to the server's FTP port (the default is 21), the server accepts the connection, and establishes a command link. When the data needs to be transferred, the client tells the server on the command link using the port command: "I opened the ***x port and you came to connect me." The server then sends a connection request from Port 20 to the client's ***x port, creating a data l
