This article introduces the relevant knowledge of "what is the use of TFTP server". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

TFTP is the abbreviation of TrivialFileTransferProtocol, which means simple file transfer protocol in Chinese translation. TFTP protocol is a protocol used for simple file transfer between client and server in the TCP/IP protocol family, and its default port number is 69.

TFTP completes the file transfer function according to the UDP protocol, unlike FTP, TFTP is planned as a small file transfer function at the beginning of development, it does not have as many strong functions as FTP service, for example: TFTP can only access or write files on the server, but can not list server file directories like FTP.

What is the use of the tftp server?

Usually VPS or other servers have their own TFTP server functions, which do not need to be configured independently, but they are closed by default and require users to open them on their own (see: VPS Open TFTP Server Rookie tutorial). Of course, the establishment and configuration of TFTP servers can also use special software like FTP servers. In this way, the configuration and application of TFTP server are more convenient (refer to: what are the common TFTP server software?).

Tftp server software

The transmission form of TFTP server is only in the form of 8-bit data transmission of netASCII and octet. The main effect of TFTP server is not as extensive as FTP server, but it can complete the function of transferring configuration files and upgrade packages between devices and computers in many devices, such as routers, switches, firewalls and so on. Of course, website programs and data can also be transferred to the device through TFTP for recovery and backup or upgrade the system.

Many webmasters or server operation and maintenance administrators still use FTP for relevant data backup and other operations when using or managing the server, but because TFTP has no messy interactive access interface and authentication control, there is no need for messy interaction between the TFTP client and the TFTP server, so it is often used by server operation and maintenance administrators.
