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

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 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 <"name value">
              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 <"name value">
              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.
