NAME
       atftp - TFTP client (RFC1350).

SYNOPSIS
       atftp [options] [host [port]]

DESCRIPTION
       atftp can be used interactively or in batch mode to retrieve files from
       TFTP servers. When used interactively, a summary of the commands can be
       printed	by  typing  'help'. This TFTP client support all basic feature
       from RFC1350, RFC2347, RFC2348 and RFC2349. It also  support  multicast
       implementation  of  RFC2090  and mtftp as defined in the PXE specifica‐
       tion.

OPTIONS
       This program supports both the usual GNU command line syntax, with long
       options	starting  with two dashes (`-') as well as short options. Some
       options are usable in batch mode only, they have no meaning when	 atftp
       is use interactively. A description of the options is included below.

       -g, --get
	      Non interactive invocation only. Instruct atftp to get file.

       --mget Non  interactive	invocation only. Used to get file from a mtftp
	      capable server.

       -p, --put
	      Non interactive invocation only. Instruct atftp to put file.

       -l, --local-file
	      Non interactive invocation only. The client side	file  name  to
	      read or write. Must be used in conjunction with --get or --put.

       -r, --remote-file
	      Non  interactive	invocation  only. The server side file name to
	      get or put. Must be used in conjunction with --get or --put.

       --tftp-timeout <value>
	      Number of seconds for timeout, client side. Default  is  5  sec‐
	      onds.

       --option <"name value">
	      Set  option  "name" to "value". This command support exactly the
	      same  arguments  as  the	interactive  one.  For	example,  use:
	      --option blksize 1428 to configure block size.

       --mtftp <"name value">
	      Set  mtftp  possible  options.  Accept  the  same options as the
	      interactive mtftp command. For example, use: --mtftp client-port
	      76 to configure client side port to use.

       --no-source-port-checking
	      See atftpd's man page.

       --prevent-sas
	      Address	the   Sorcerer's   Apprentice  Syndrome	 situation  as
	      requested by RFC 1350.  This RFC requires repeated responses  to
	      a	 single	 packet	 to  be	 rejected.  Thus a block will only get
	      retransmitted on a timeout.   For	 backward  compatibility,  the
	      default  stays to ignore this RFC.  So blocks get transmitted on
	      every request.

       --verbose
	      Instruct atftp to be verbose. It	will  print  more  information
	      about what's going on.

       --trace
	      This is useful for debugging purpose to display all packet going
	      to and from the network.

       -V, --version
	      Print version.

       -h, --help
	      Print a summary of command line arguments.
