NAME    [Toc]    [Back]

     tftp - trivial file transfer program

SYNOPSIS    [Toc]    [Back]

     tftp [ host ]

DESCRIPTION    [Toc]    [Back]

     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    [Toc]    [Back]

     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
	  connections 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.

     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 hostname
	  specified becomes the	default	for future transfers.  If the remotedirectory
 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.

BUGS    [Toc]    [Back]

     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.  See tftpd(1M)	for details about customizing
     file-access restrictions on IRIX.
