    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 recog-
         nizes 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 connections 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 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 host-
    	  name 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 restrictions in place.  The exact methods are
         specific to each site and therefore difficult to document
         here.
