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 authentica-
          tion information, tftpd will allow only publicly  read-
          able  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 net-
          work;  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.
