tftp — trivial
file transfer program
Tftp is the user interface to the Internet
TFTP (Trivial File Transfer Protocol), which allows users to transfer files
to and from a remote machine. The remote host may be
specified on the command line, in which case
uses host as the default host for future transfers
connect command below).
tftp is running, it issues the prompt
"tftp> " and recognizes the following commands:
- Print help information.
- Shorthand for "mode ascii"
- Shorthand for "mode binary"
- Set the host (and optionally
port) for transfers. Note that the TFTP protocol,
unlike the FTP protocol, does not maintain connections betwen transfers;
connectcommand does not actually create a connection, but merely remembers what host is to be used for transfers. You do not have to use the
connectcommand; the remote host can be specified as part of the
getfile1 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 hosts: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.
- Set the mode for transfers; transfer-mode may be one of ascii or binary. The default is ascii.
putfile1 file2 ... fileN 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 hosts: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 machine.

- Set the per-packet retransmission timeout, in seconds.
- Show current status.
- Set the total transmission timeout, in seconds.
- Toggle packet tracing.
- Toggle verbose mode.
Because there is no user-login or validation within the TFTP protocol, the remote site will probably have some sort of file-access restrictions in place. The exact methods are specific to each site and therefore difficult to document here.
