NAME
       tftp - IPv4 Trivial File	Transfer Protocol client

SYNOPSIS
       tftp [options...]  [host]

DESCRIPTION
       tftp is a client	for the	IPv4 Trivial file Transfer Protocol, which can
       be used to transfer files to and	from remote machines,  including  some
       very  minimalistic,  usually embedded, systems.	The remote host	may be
       specified on the	command	line, in which case tftp uses host as the  de-
       fault host for future transfers (see the	connect	command	below.)

OPTIONS
       -v     Default to verbose mode.

       -V     Print  the  version number and configuration to standard output,
	      then exit	gracefully.

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

       ? command-name...

       help command-name...
	      Print help information

       ascii  Shorthand	for mode ascii.

       binary Shorthand	for mode binary.

       connect host [port]
	      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 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.

       get file
       get remotefile localfile
       get file1 file2 file3...
	      Get a file or set	of files from the specified sources.  A	remote
	      filename can be in one of	two forms: a plain filename on the re-
	      mote  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.

       mode transfer-mode
	      Specify the mode for transfers;  transfer-mode  may  be  one  of
	      ascii (or	netascii) or binary (or	octet.)	 The default is	ascii.

       put file
       put localfile remotefile
       put file1 file2 file3...	remote-directory
	      Put  a  file or set of files to the specified remote file	or di-
	      rectory.	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
	      hostname specified becomes the default for future	transfers.  If
	      the remote-directory form	is used, the remote host is assumed to
	      be a UNIX	system or another system using / as directory  separa-
	      tor.

       quit   Exit tftp.  End-of-file will also	exit.

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

       status Show current status.

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

       trace  Toggle packet tracing (a debugging feature.)

       verbose
	      Toggle verbose mode.

NOTES
       The  TFTP  protocol  provides no	provisions for authentication or secu-
       rity.  Therefore, the remote server will	probably implement some	 kinds
       of  access  restriction	or firewalling.	 These access restrictions are
       likely to be site- and server-specific.

AUTHOR
       This version of tftp is maintained by H.	Peter  Anvin  <hpa@zytor.com>.
       It  was	derived	 from, but has substantially diverged from, an OpenBSD
       source base, with added patches by Markus Gutschke and Gero Kulhman.
