tftpd - DARPA Trivial File Transfer Protocol server
/etc/tftpd [ -d ] [ port ]
Tftpd is a server which supports the DARPA Trivial File Transfer Proto-
col. The TFTP server operates at the port indicated in the ``tftp''
service description; see services(5). This port number may be overrid-
den (for debugging purposes) by specifying a port number on the command
line. If the -d option is specified, each socket created by tftpd will
have debugging enabled (see SO_DEBUG in socket(2)).
The use of tftp 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. 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
This server is known only to be self consistent (i.e. it operates with
the user TFTP program, tftp(1C)). Due to the unreliability of the
transport protocol (UDP) and the scarcity of TFTP implementations, it
is uncertain whether it really works.
The search permissions of the directories leading to the files accessed
are not checked.
