NAME

tftp − trivial file transfer program

SYNOPSIS

tftp [host]

DESCRIPTION

tftp 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 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:

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 can be one of ascii or binary (default is ascii). 

put file

put localfile remotefile

put file1 file2 ... fileN  remotedirectory
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 remote-directory form is used, the remote host is assumed to be a UNIX-like 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.  Typing the end-of-file character also causes an exit. 

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.

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.
