NAME
       tftp - trivial file transfer program

SYNOPSIS
       tftp [ host ]

DESCRIPTION
       Tftp  is the user interface to the Internet TFTP (Trivial File Transfer
       Protocol), which allows users to transfer files to and  from  a  remote
       machine.   The  remote  host  may  be specified on the command line, in
       which case tftp uses host as the default host for future transfers (see
       the connect command below).

COMMANDS
       Once  tftp  is  running,  it issues the prompt tftp> and recognizes the
       following commands:

       connect host-name [ port ]
              Set the host (and optionally port) for transfers.  Note that the
              TFTP  protocol,  unlike the FTP protocol, does not maintain con‐
              nections betweeen transfers; thus, the connect command does  not
              actually  create a connection, but merely remembers what host is
              to be used for transfers.  You do not have to  use  the  connect
              command;  the remote host can be specified as part of the get or
              put commands.

       mode transfer-mode
              Set the mode for transfers; transfer-mode may be one of ascii or
              binary.  The default is ascii.

       put file
       put localfile remotefile
       put file1 file2 ... fileN remote-directory
              Put  a  file  or  set  of  files to the specified remote file or
              directory.  The destination can be in one of two forms: a  file‐
              name on the remote host, if the host has already been specified,
              or a string of the form host:filename to specify both a host and
              filename  at  the  same  time.   If the latter form is used, the
              hostname specified becomes the default for future transfers.  If
              the remote-directory form is used, the remote host is assumed to
              be a UNIX machine.

       get filename
       get remotename localname
       get file1 file2 ... fileN
              Get a file or set of files from the specified  sources.   Source
              can  be  in  one of two forms: a filename on the remote host, if
              the host has already been specified, or a  string  of  the  form
              host:filename  to  specify  both a host and filename at the same
              time.  If the latter form is used, the last  hostname  specified
              becomes the default for future transfers.

       quit   Exit tftp.  An end of file also exits.

       verbose
              Toggle verbose mode.

       trace  Toggle packet tracing.

       status Show current status.

       rexmt retransmission-timeout
              Set the per-packet retransmission timeout, in seconds.

       timeout total-transmission-timeout
              Set the total transmission timeout, in seconds.

       ascii  Shorthand for "mode ascii"

       binary Shorthand for "mode binary"

       ?  [ command-name ... ]
              Print help information.

BUGS
       Because  there is no user-login or validation within the TFTP protocol,
       the remote site will probably have some sort  of  file-access  restric‐
       tions in place.  The exact methods are specific to each site and there‐
       fore difficult to document here.
