NAME
       tftp - trivial file transfer program

SYNOPSIS
       val] val] [host [port]]

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

   Note
       now conforms to the RFCs: 2347, 2348, and 2349.

   Options
       supports the following new options:

	      Set the block size option for data transfer, in octets. See
			  command for more information.

	      Set the use of transfer size option. See
			  command for more information.

	      Set the retransmission timeout option, in seconds. See
			  command for more information.

   Commands
       Once is running, it issues the prompt and recognizes the following commands:

	      Set the	  host	(and optionally port) for transfers.  Note that the TFTP protocol, unlike the FTP protocol, does not maintain con-
			  nections between transfers; thus, the 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 command; the remote host can be specified as part of the or com-
			  mands.

	      Set the mode for transfers;
			  transfer-mode can be one of or (default is

	      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 to specify both a host and filename at the same time.  If the latter form is used, the hostname spec-
			  ified becomes the default for future transfers.  If the remote-directory form is used, the remote host is assumed to	be
			  a UNIX-like machine.

	      To invoke the
			  command with an IPv6 address, the IPv6 address must be enclosed in a pair of square brackets

	      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 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.

	      To invoke the
			  command with an IPv6 address, the IPv6 address must be enclosed in a pair of square brackets

	      Exit	  Typing the end-of-file character also causes an exit.

	      Toggle verbose mode.

	      Toggle packet tracing.

	      Show current status.

	      Set the per-packet retransmission timeout, in seconds.

	      Set the total transmission timeout, in seconds.

	      Shorthand for "mode ascii"

	      Shorthand for "mode binary"

	      Set the block size for data transfer. The client and the server communicate
			  to  arrive  upon a block size that is suitable for use on the network medium.  The valid range is 8 to 65464 octets. The
			  default value is 512 octets.

	      Set the retransmission timeout, in seconds. The client and the server
			  communicate to arrive upon a retransmission timeout value.  The valid range is 1 to 255 seconds. The default value is  5
			  seconds.

	      Toggles the use of transfer size. This option is implemented for binary mode
			  transfers  only. By default, this option is disabled.  If this option is enabled, it allows the receiving side to deter-
			  mine the size of the file being transferred. When the command is used in binary mode and the size of the file is greater
			  than the free disk space, transfer will be aborted immediately. When the command is used in binary mode, the size of the
			  file will be sent to the server.

	      Print help information.

WARNINGS
       Since there is no user-login or validation within the TFTP protocol, the remote site probably has some sort of file-access restrictions	in
       place.  The exact methods are specific to each site and are therefore difficult to document here.
