tftp(1)

Set the block size option for data transfer, in octets. See blksize command for more information.

Set the use of transfer size option. See tsize command for more information.

Set the retransmission timeout option, in seconds. See newrexmt command for more information.

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.

Set the mode for transfers; transfer-mode can be one of ascii or binary (default is ascii).

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.

To invoke the put command with an IPv6 address, the IPv6 address must be enclosed in a pair of square brackets ([ and ])

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.

To invoke the get command with an IPv6 address, the IPv6 address must be enclosed in a pair of square brackets ([ and ])

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

Toggle verbose mode.

Toggle packet tracing.

Set the per-packet retransmission timeout, in seconds.

Set the total transmission timeout, in seconds.

Shorthand for "mode binary"

Set the block size for data transfer. The client and the server communicate to arrive upon a block size that is suitable for use on the network medium. The valid range is 8 to 65464 octets. The default value is 512 octets.

Set the retransmission timeout, in seconds. The client and the server communicate to arrive upon a retransmission timeout value. The valid range is 1 to 255 seconds. The default value is 5 seconds.

Toggles the use of transfer size. This option is implemented for binary mode transfers only. By default, this option is disabled. If this option is enabled, it allows the receiving side to determine the size of the file being transferred. When the get command is used in binary mode and the size of the file is greater than the free disk space, transfer will be aborted immediately. When the put command is used in binary mode, the size of the file will be sent to the server.
