When we use the tcp ip protocol for transmission management, many of its protocols have more or less security problems. Now let's take a look at the security issues related to the FTP File Transfer Protocol. In this case, we hope you can clarify the principles in this regard.

The FTP Port mode brings many problems to network administrators. First
access. When a higher performance and stability system is required, UNIX should be selected. FreeBSD is clearly a very good WWW server operating system to choose from when using Intel platform systems.
Basic concepts
Although ordinary users only need to understand some common sense concepts, such as URLs, HTML, and so on, they can easily access web resources on the Internet through the browser. However, to build a Web server, you need more relevant concepts, such as HTTP, MIME, CGI, and so on
specific implementations are called user PI and server PI respectively.
5) server DTP:
During the data transmission process, a data connection is usually established using the "listener" data port in the "active" status. It establishes transmission and storage parameters and
PI command to transfer data. Server-side DTP can also be used in "passive" mode, rather than actively establishing a connection on the data port.

As a basic FTP File Transfer Protocol, TCP is a common download management protocol. So how can we achieve file transfer and effective download? Let's take a closer look at the following articles. Let's take a look at the FTP file transmission mode.
