NAME

tftp - trivial ﬁle transfer program

SYNOPSIS

tftp [ -B val ][-s

][-t val ][host [port ]]

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).

Note

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

Options

tftp supports the following new options:

-B val Set the block size option for data transfer, in octets. See

blksize command for more

information.

-s Set the use of transfer size option. See

tsize command for more information.

-t val Set the retransmission timeout option, in seconds. See

newrexmt command for more

information.

Commands

Once

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

connect host [ 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 con-

nect 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.

put localfile [IPv6_address]:remotefile

To invoke the put command with an IPv6 address, the IPv6 address must be enclosed

in a pair of square brackets ([ and ])

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.

get [IPv6_address]:remotename localname

To invoke the get command with an IPv6 address, the IPv6 address must be enclosed

in a pair of square brackets ([ and ])

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