tftpd − DARPA Trivial File Transfer Protocol server


tftpd [directory ...]


Tftpd is a server which supports the DARPA Trivial File Transfer Protocol. The TFTP server operates at the port indicated in the ’tftp’ service description; see services(5). The server is normally started by inetd(8).

The use of tftp(1) does not require an account or password on the remote system. Due to the lack of authentication information, tftpd will allow only publicly readable files to be accessed. Files may be written only if they already exist and are publicly writable. Note that this extends the concept of ‘‘public’’ to include all users on all hosts that can be reached through the network; this may not be appropriate on all systems, and its implications should be considered before enabling tftp service. The server should have the user ID with the lowest possible privilege.

Access to files may be controlled by invoking tftpd with a list of directories by including pathnames as server program arguments in /etc/inetd.conf. In this case access is restricted to files whose names are prefixed by the one of the given directories. If no directories are supplied the default is /tftpboot. To give out access to the whole filesystem, should this be desired for some reason, supply / as an argument.

The tftpd command appeared in 4.2BSD.
