TFTPD(8) BSD System Manager's Manual TFTPD(8)
NAME
tftpd -- DARPA Trivial File Transfer Protocol server
SYNOPSIS
tftpd [-n] [-s] [directory ...]
DESCRIPTION
Tftpd is a server which supports the DARPA Trivial File Transfer Protocol. The TFTP server operates at the port indicated in the 'tftp' ser-
vice 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.
Unfortunately, on multi-homed systems, it is impossible for tftpd to determine the address on which a packet was received. As a result, tftpd
uses two different mechanisms to guess the best source address to use for replies. If the socket that inetd(8) passed to tftpd is bound to a
particular address, tftpd uses that address for replies. Otherwise, tftpd uses ``UDP connect'' to let the kernel choose the reply address
based on the destination of the replies and the routing tables. This means that most setups will work transparently, while in cases where the
reply address must be fixed, the virtual hosting feature of inetd(8) can be used to ensure that replies go out from the correct address.
These considerations are important, because most tftp clients will reject reply packets that appear to come from an unexpected address.
The options are:
-n Suppresses negative acknowledgement of requests for nonexistent relative filenames.
-s All absolute filenames are treated as if they were preceded by the first directory argument, or /tftpboot if there is none.

HISTORY
The tftpd command appeared in 4.2BSD.
