TFTP(1)			FreeBSD	General	Commands Manual		       TFTP(1)

NAME
     tftp -- trivial file transfer program

SYNOPSIS
     tftp [host]

DESCRIPTION
     The tftp utility 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:

     ? command-name ...
	      Print help information.

     ascii    Shorthand	for "mode ascii"

     binary   Shorthand	for "mode binary"

     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 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 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
	      hosts: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
	      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 hosts: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.  If you need to specify IPv6 numeric address
	      to hosts,	wrap them using	square bracket like [hosts]:filename
	      to disambiguate the colon.

     quit     Exit tftp.  An end of file also exits.

     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.

     verbose  Toggle verbose mode.

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 dif-
     ficult to document	here.

     Files larger than 33488896	octets (65535 blocks) cannot be	transferred
     without client and	server supporting blocksize negotiation	(RFC1783).

HISTORY
     The tftp command appeared in 4.3BSD.

FreeBSD	10.1			April 18, 1994			  FreeBSD 10.1
