TFTPD(8)                OpenBSD System Manager's Manual               TFTPD(8)

     tftpd - DARPA Trivial File Transfer Protocol server

     tftpd [directory ...]
     tftpd -cs [directory]

     Tftpd is a server which supports the DARPA Trivial File Transfer Proto-
     col.  The TFTP server operates at the port indicated in the `tftp' ser-
     vice description; see services(5).  The server is normally started by

     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 restricted by invoking tftpd with a list of direc-
     tories 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 the -c flag is used, tftpd will allow new files to be created; other-
     wise uploaded files most already exist.  Files are created with default
     permissions allowing anyone to read or write to them.

     When using the -s flag with a directory name, tftpd will chroot(2) on
     startup; therefore the remote host is not expected to pass the directory
     as part of the file name to transfer.  This option is intended primarily
     for compatibility with SunOS boot ROMs which do not include a directory

     tftp(1),  inetd(8)

     The tftpd command appeared in 4.2BSD.

     The -s flag appeared in NetBSD 0.9a.

     The -c flag was added in OpenBSD 2.1.
