Use this page to configure and enable remote users to access the TCP/IP server TFTPD on this computer. The server uses Trivial File Transfer Protocol to make data on this computer available to the remote user's computer. TFTP lets you define the remote computer's read, write, drive, and directory accesses. Like FTP, TFTP can transfer files in ASCII or binary form, but unlike FTP it can only transfer files one at a time and does not provide subcommands; for example, commands that list or change directories at a remote host. TFTP uses the less-reliable User Datagram Protocol (UDP), rather than TCP/IP, for data transfer and therefore should not be considered an equivalent substitute for FTP.
TFTP information is saved in TFTPAUTH.
