Ubuntu Configuration TFTP server

The TFTP (Trivial file Transfer Protocol, simple Files Transfer Protocol) is a protocol used by the TCP/IP protocol family to perform simple file transfer between the client and server, providing an uncomplicated, inexpensive file transfer service. The port number is 69.

TFTP is implemented based on the UDP protocol, but we are not sure that some TFTP protocols are based on other transport protocols. This protocol is designed for small file transfer, so it does not have many of the usual FTP features, it can only be obtained from the file server or write to the file, cannot list the directory, not authentication, it transmits 8 bits of data, through the time-out retransmission method to ensure the arrival of data.
