Tftp
Updated: January 21, 2005
Transfers files to and from a remote computer, typically a
computer running UNIX, that is running the Trivial File Transfer
Protocol (TFTP) service or daemon. Used without parameters,
tftp displays help.
Syntax
tftp [-i] [Host] [{get | put}]
[Source] [Destination]
Parameters
-i
Specifies binary image transfer mode (also called
octet mode). In binary image mode, the file is
transferred in one-byte units. Use this mode when
transferring binary files. If -i is omitted,
the file is transferred in ASCII mode. This is the
default transfer mode. This mode converts the
end-of-line (EOL) characters to an appropriate
format for the specified computer. Use this mode
when transferring text files. If a file transfer is
successful, the data transfer rate is displayed.
Host
Specifies the local or remote computer.
put
Transfers the file Destination on the local
computer to the file Source on the remote
computer. Because the TFTP protocol does not support
user authentication, the user must be logged onto
the remote computer, and the files must be writable
on the remote computer.
get
Transfers the file Destination on the remote
computer to the file Source on the local
computer.
Source
Specifies the file to transfer.
Destination
Specifies where to transfer the file. If
Destination is omitted, it is assumed to have
the same name as Source.
/?
Displays help at the command prompt.
Remarks
-
Using the get parameter
Specify put if transferring file FileTwo on the local computer to file FileOne on remote computer. Specify get if transferring file FileTwo on the remote computer to file FileOne on the remote computer.
- The Windows Server 2003 family and Windows 2000 do not provide a general purpose TFTP server. Windows 2000 provides a TFTP server service only to provide remote boot capabilities to Windows XP and Windows 2000 client computers.
- This command is available only if the Internet Protocol (TCP/IP) protocol is installed as a component in the properties of a network adapter in Network Connections.
Examples
To transfer the file Users.txt from the local computer to the
file Users19.txt on a remote computer named vax1, type:
tftp vax1 put users.txt users19.txt
