Name¶

tftp

– IPv4 Trivial File Transfer Protocol client

Notes¶

The TFTP protocol provides no provisions for authentication or security.
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.

Connect with IPv6 only, if compiled in.
-ccommand

Tftp command syntax

We will use following syntax for tftp command in normal command-line usage.

tftp HOST

Tftp man page – general commands | mankier

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

?command-name…
helpcommand-name…

Print help information

ascii

Shorthand for mode ascii.

binary

Shorthand for mode binary.

connecthost [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.

getfile
getremotefile localfile
getfile1 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 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.  Enable literal mode to prevent special treatment of the ‘:’ character (e.g. C:dirfile).

literal

Toggle literal mode.  When set, this mode prevents special treatment of ‘:’ in filenames.

modetransfer-mode

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

putfile
putlocalfile remotefile
putfile1 file2 file3… 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 remote-directory form is used, the remote host is assumed to be a UNIX system or another system using / as directory separator.  Enable literal mode to prevent special treatment of the ‘:’ character (e.g. C:dirfile).

quit

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

rexmtretransmission-timeout

Set the per-packet retransmission timeout, in seconds.

status

Show current status.

timeouttotal-transmission-timeout

Set the total transmission timeout, in seconds.

trace

Toggle packet tracing (a debugging feature.)

verbose

Toggle verbose mode.

Tftp server command line interactive shell

After connection to the Tftp server, we will get an interactive shell. In this shell, we will issue commands to get information about status of the connection, download or get files, upload, or put files to the server. We can list available commands provided by Tftp shell with ? .

?

Upload or put file to the tftp server

We can upload or put files to the TFTP server with the put command. In the example, we upload a file named body.txt

put body.txt

Verbose mode

While making transfer we may need more information about the transmission. We can get more information about the transfer with the verbose mode.

verbose

Проект opennet: man tftp (1) команды и прикладные программы пользовательского уровня (freebsd и linux)

host

argument, the
host

will be used as default host for future transfers.
If
localname

is specified, the file is stored locally as
localname

otherwise the original filename is used.
Note that it is not possible to download two files at a time, only
one, three, or more than three files, at a time.

To specify an IPv6 numeric address for a host, wrap it using square
brackets like
[3ffe:2900:e00c:ffee::1234] : file

to disambiguate the
colons used in the IPv6 address from the colon separating the host and
the filename.
