SYNOPSIStftp [ host ]
DESCRIPTION
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 tftp uses host as the default host for future transfers (see
the connect command below).
COMMANDS
Once tftp is running, it issues the prompt tftp> and recognizes the
following commands:
connect host-name [ 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.
mode transfer-mode
Set the mode for transfers; transfer-mode may be one of ascii or
binary. The default is ascii.
put file
put localfile remotefile
put file1 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 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 machine.
get filename
get remotename localname
get file1 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
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.
quit Exit tftp. An end of file also exits.
verbose
Toggle verbose mode.
trace Toggle packet tracing.
status Show current status.
rexmt retransmission-timeout
Set the per-packet retransmission timeout, in seconds.
timeout total-transmission-timeout
Set the total transmission timeout, in seconds.
ascii Shorthand for "mode ascii"
binary Shorthand for "mode binary"
? [ command-name ... ]
Print help information.
BUGS
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.
