tftpd(1M)                        (TCP/IP)                         tftpd(1M)


   NAME
         tftpd - DARPA Trivial File Transfer Protocol server

   SYNOPSIS
         in.tftpd [ -s ] [ homedir ]

   DESCRIPTION
         tftpd is a server that supports the DARPA Trivial File Transfer
         Protocol (TFTP).  This server is normally started by inetd(1M) and
         operates at the port indicated in the tftp Internet service
         description in the /etc/inetd.conf file. By default, the entry for
         tftpd in etc/inetd.conf is commented out.  To make tftpd operational,
         the comment character(s) must be deleted from the file.  See
         inetd.conf(4) for details.

         Before responding to a request, the server attempts to change its
         current directory to homedir; the default value is /tftpboot.

   OPTIONS
         -s    Secure.  When specified, the directory change must succeed; and
               the daemon also changes its root directory to homedir.

               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.
               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 this service.

         tftpd runs with the user ID and group ID set to [GU]ID_NOBODY.  -2,
         under the assumption that no files exist with that owner or group.
         However, nothing checks this assumption or enforces this restriction.
