TFTP is a simplified version of the File Transfer Protocol
(FTP). The primary function of the TFTP daemon tftpd is to support the Bootstrap Protocol BOOTP, which allows network devices to get the information
they need to boot, or start, themselves. Network devices commonly
use TFTP to transmit boot files because TFTP is simple enough to be implemented in ROM.
On the HP e3000, the TFTP daemon tftpd transfers files to or from the host HP e3000 to
remote systems or printers. Configuring tftpd on your system allows you to make boot files (and
other kinds of files) available to remote clients that support TFTP.
