Is there any good FTP site that is best recommended by category

FTP sites of some universities in China: Tsinghua University.

Peking university. Beijing University of Posts and Telecommunications, Huazhong University of Science and Technology.

Jinan University, Dalian University of Technology, Shanghai Jiaotong University, Tongji University, Nanjing University, Nanjing Institute of Posts and Telecommunications, Nanjing University of Science and Technology, Zhejiang University, University of Science and Technology of China, Xiamen University, Shandong University, Harbin Institute of Technology, Harbin Jianzhu University, Wuhan University of Surveying and Mapping, Wuhan University of Water Conservancy and Electric Power, Zhongnan University of Finance and Economics, Central South University of Technology, Changsha Railway College, National University of Defense Technology, South China University of Technology, Shenzhen University, Sun Yat-sen University, Xi'an Jiaotong University, Chinese University of Hong Kong, Tongji University.

I haven't seen it so far, most of them ask for money, and many of them can't get in.

Nowadays, the common ones are lightweight and easy to use. For example, these flashfxp are as follows:

leapftp

There are too many FTP software of this kind, and Lao Wei commonly uses WinFFP in the Wei Ace note server is the SFTP software, which is similar to the FTP protocol and is easier to use.

At the same time, the IIS7 server management tool also has a batch management function, which can manage WinUWS and Linux series systems in batches, and can also be used as a client of VNC, which can fully meet the needs of webmasters and operation and maintenance staff.

FTP sites are also known as FTP servers. You need the FTP server IP port username and password to log in.

IIS7 server management tool can manage FTP sites in bulk, free of charge, you can try.

The tool also supports batch management of remote desktop vnc. for each system

File Transfer Protocol (FTP, FileTransfer)

protocol) is a software standard for transferring computer files between two machines with different operating systems. It belongs to the application layer of the network protocol group.

FTP is an 8-bit client-server protocol that can manipulate any type of file without further processing, just like MIME or UNENCODE. However, FTP has extremely high latency, which means that the time between the start of the request and the first receipt of the required data can be very long, and some lengthy login processes must be performed from time to time.

The FTP service generally runs on ports 20 and 21. Port 20 is used to transmit the data stream between the client and the server, while port 21 is used to transmit the control stream and is the import of the command to the FTP server. While data is transmitted through the data stream, the control flow is idle.

When the control flow is idle for a long time, the client's firewall will time out its session, which can cause problems when a large amount of data passes through the firewall. At this point, although the file can be successfully transferred, there will be some errors in the transfer because the control session will be disconnected by the firewall.

What FTP achieves:

1. Facilitate the sharing of files (computer programs or data).

2. Encourage indirect or implicit use of remote computers.

3. Block the details of various file storage systems in different hosts to users.

4. Reliable and efficient data transmission.

Disadvantages: 1. Passwords and file contents are transmitted in plaintext, which may lead to undesirable eavesdropping.

2. Because a random port must be opened to establish a connection, it is difficult for the client to filter FTP traffic in active mode when a firewall exists. This problem is greatly solved by FTP by using passive mode.

3. The server may be told to connect to a reserved port of a third-party computer.

Many sites running FTP services have an anonymous service, in which users do not need an account to log in to the server, and by default, the username of anonymous users is: "anonymous". This account does not require a password, although it usually requires the user's email address to be used as the authentication password, but this is only a few details or the email address is not determined at all, and depends on the configuration of the FTP server.

FTP has two modes of use: active and passive. Active mode requires both the client and server to open and listen on a port at the same time to establish a connection.

In this case, the client will have some problems due to the firewall installed. So, the passive mode was created. The passive mode only requires the server to generate a process that listens on the corresponding port, so that the problem of the firewall installed by the client can be bypassed.

I hope the occasional can help you!!

As long as you have a username and password, you can log in to the ftp server Tachibana Toshi.

It's about the same as a USB flash drive. But its files are saved on an FTP server.
