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  features  from  RFC1350, RFC2347, RFC2348 and RFC2349. It also support multicast implementation of
       RFC2090 and mtftp as defined in the PXE specification.

       atftp - TFTP client (RFC1350).

       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 shown below.

       -g,--get
              Non interactive invocation only. Instruct atftp to fetch a file from a tftp server.

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

       -p,--put
              Non interactive invocation only. Instruct atftp to send a file to a tftp server.

       -P,--password
              Give password to tftp server. This is a non-standard extension to the atftp client  necessary  for
              Linksys routers and shouldn't be used elsewhere.

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

       --tftp-timeout<value>
              Number of seconds for timeout of the client. Default is 5 seconds.

       --option<"namevalue">
              Set option "name" to "value". This command supports exactly the same arguments as the  interactive
              one. For example, use: --option "blksize 1428" to configure block size.
              Possible settings are:
                --option "blksize disable"
                --option "blksize 8"
                --option "blksize 65464"
                --option "timeout 1"
                --option "tsize enable"
                --option "tsize disable"
                --option "windowsize disable"
                --option "windowsize 4"
                --option "multicast"

       --mtftp<"namevalue">
              Set  mtftp  possible  options.  Accepts  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.
