USING TFTP IN DOS

TFTP (Trivial File Transfer Protocol) lets you transfer files between
your DOS workstation and a remote host that is running a TFTP server
program. TFTP does not require a password.

Note: Before you can successfully transfer a file to or from a remote
host, a destination file of the same name must exist and it must have
universal ("other") write permission.


TRANSFERRING FILES

To copy a file from your workstation to a remote host, enter a TFTP
command in the following format:

      TFTP [ -B ] [ -D ] [ -P port_number ] [ -V ]
            source remote_host=destination

To copy a file from a remote host to your DOS workstation, enter a
TFTP command in the following format:

      TFTP [ -B ] [ -D ] [ -P port_number ] [ -V ]
            remote_host=source destination

The TFTP command-line options and parameters are listed and
briefly described in Table 3-6 [below].

The following example shows you how to copy the file
MARCH\ACCOUNTS.TXT from your workstation to the directory
/x/march/ on the remote UNIX host sales. To do this, enter the
following command:

      C:\> TFTP MARCH\ACCOUNTS.TXT
            sales=/x/march/accounts.txt

The destination directory (/x/march) must exist on the remote host
and the destination file (accounts.txt) must exist in /x/march and
have universal ("other") write permission.

The following examples show you how to copy the file
/february/accounts.txt from the remote UNIX host sales to the
current directory on your workstation. To do this, enter the
following command:

      C:\> TFTP sales=/february/accounts.txt

To redirect the contents of the file /february/accounts.txt to your
screen, enter either of the following commands:

      C:\> TFTP sales=/february/accounts.txt -

or

      C:\> TFTP sales=/february/accounts.txt - | MORE

Table 3-6 [below] describes the options and parameters used with the TFTP
command.


            Table 3-6: TFTP Options and Parameters
============================================================
Options and Parameters   Description
============================================================

-B                       Enables 8-bit binary transfer mode.
                         This mode is required when transferring
                         binary files. If you do not specify
                         this option, the transfer mode is ASCII.

                         When transferring files between a remote
                         host and your DOS workstation, this
                         option lets you copy ASCII files without
                         converting them. (When transferring
                         files, data conversion is required when
                         the ASCII file format on the other system
                         is different from the DOS format.)

-D                       Enables debugging mode. When the debugging
                         mode is on, TFTP displays each
                         command sent to the remote host.

-P port_number           Selects an alternate port number for
                         establishing a TFTP connection with the
                         remote server. The standard TFTP port
                         number is 69.

-V                       Enables verbose mode. When on,
                         all responses from the TFTP server are
                         displayed.

source                   Name of the file you want to copy to
                         destination. You  must specify source
                         as a full or partial path name, if it
                         is on your DOS workstation but is not in the
                         current directory. You must specify source
                         as a full path name if it is on the
                         remote host.

remote_host              Name of the remote host. It must be
                         followed by an equal sign (=).

destination              Name given to the file when it is
                         copied. You must specify destination
                         as a full path name, if the directory
                         to which you are copying source is not the
                         current directory. If you omit destination,
                         and source is on your DOS workstation,
                         TFTP copies source to the current directory
                         on remote_host under the same name. If you
                         omit destination, and source is on the remote
                         host, TFTP copies the file to the current
                         directory on your DOS workstation
                         under the same name.
