NAME
      in.tftpd, tftpd - Internet Trivial  File  Transfer  Protocol
      server
 


SYNOPSIS
      in.tftpd [ -s ]  [ homedir ]
 


DESCRIPTION
      tftpd is a server that supports the  Internet  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 in.tftpd in  etc/inetd.conf  is  com-
      mented  out.   To  make  in.tftpd  operational,  the comment
      character(s)  must   be   deleted   from   the   file.   See
      inetd.conf(4).
 
      Before responding to  a  request,  the  server  attempts  to
      change  its current directory to homedir; the default direc-
      tory is /tftpboot.
 
      The use of tftp does not require an account or  password  on
      the  remote system. Due to the lack of authentication infor-
      mation, in.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 net-
      work; this may not be appropriate on all  systems,  and  its
      implications  should be considered before enabling this ser-
      vice.
 
      in.tftpd  runs  with  the  user  ID  and  group  ID  set  to
      [GU]ID_NOBODY  under the assumption that no files exist with
      that owner or group.  However, nothing checks  this  assump-
      tion or enforces this restriction.
 


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


FILES
      /etc/inetd.conf"
 
 USAGE
      The in.tftpd server is IPv6-enabled. See ip6(7P).
