tftp - trivial file transfer program
SYNOPSIS
tftp
[
host
]
AVAILABILITY
This command is available with the
Networking
software installation option. Refer to
[a manual with the abbreviation INSTALL]
for information on how to install optional software.
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).
USAGE
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: 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 filename
-
- put localfile remotefile
-
- put filename1 filename2 ... filenameN remote-directory
-
Transfer a file, or a 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 specified host becomes the default for future transfers.
If the remote-directory form is used, the remote host is
assumed to be running the
UNIX
system.
- get filename
-
- get remotename localname
-
- get filename1 filename2 ... filenameN
-
Get a file or set of files from the specified remote
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 host specified becomes the default for future transfers.
- quit
-
Exit
tftp.
An
EOF
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.
WARNING
The default
transfer-mode
is
ascii.
This differs from pre-4.0 Sun (and pre-4.3
BSD)
releases, so explicit action must now be taken
when transferring non-ASCII
files such as executable commands.
BUGS
Because there is no user-login or validation within
the
TFTP
protocol, many remote sites restrict file access in various ways.
Approved methods for file access are specific to each site, and
therefore cannot be documented here.
