.Sh NAME
|
|
.Nm tftp
|
|
.Nd trivial file transfer program
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Ar host
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is the user interface to the Internet
|
|
.Tn TFTP
|
|
(Trivial File Transfer Protocol),
|
|
which allows users to transfer files to and from a remote machine.
|
|
The remote
|
|
.Ar host
|
|
may be specified on the command line, in which case
|
|
.Nm
|
|
uses
|
|
.Ar host
|
|
as the default host for future transfers (see the
|
|
.Cm connect
|
|
command below).
|
|
.Sh COMMANDS
|
|
Once
|
|
.Nm
|
|
is running, it issues the prompt
|
|
.Dq Li tftp>
|
|
and recognizes the following commands:
|
|
.Pp
|
|
.Bl -tag -width verbose -compact
|
|
.It Cm \&? Ar command-name ...
|
|
Print help information.
|
|
.Pp
|
|
.It Cm ascii
|
|
Shorthand for "mode ascii"
|
|
.Pp
|
|
.It Cm binary
|
|
Shorthand for "mode binary"
|
|
.Pp
|
|
.It Cm connect Ar host-name Op Ar port
|
|
Set the
|
|
.Ar host
|
|
(and optionally
|
|
.Ar port )
|
|
for transfers.
|
|
Note that the
|
|
.Tn TFTP
|
|
protocol, unlike the
|
|
.Tn FTP
|
|
protocol,
|
|
does not maintain connections between transfers; thus, the
|
|
.Cm 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
|
|
.Cm connect
|
|
command; the remote host can be specified as part of the
|
|
.Cm get
|
|
or
|
|
.Cm put
|
|
commands.
|
|
.Pp
|
|
.It Cm get Ar filename
|
|
.It Cm get Ar remotename localname
|
|
.It Cm get Ar file1 file2 ... fileN
|
|
Get a file or set of files from the specified
|
|
.Ar sources .
|
|
.Ar 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
|
|
.Ar 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.
|
|
.Pp
|
|
.It Cm mode Ar transfer-mode
|
|
Set the mode for transfers;
|
|
.Ar transfer-mode
|
|
may be one of
|
|
.Em ascii
|
|
or
|
|
.Em binary .
|
|
The default is
|
|
.Em ascii .
|
|
.Pp
|
|
.It Cm put Ar file
|
|
.It Cm put Ar localfile remotefile
|
|
.It Cm put Ar 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
|
|
.Ar 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
|
|
.Tn UNIX
|
|
machine.
|
|
If you need to specify IPv6 numeric address to
|
|
.Ar hosts ,
|
|
wrap them using square bracket like
|
|
.Ar [hosts]:filename
|
|
to disambiguate the colon.
|
|
.Pp
|
|
.It Cm quit
|
|
Exit
|
|
.Nm .
|
|
An end of file also exits.
|
|
.Pp
|
|
.It Cm rexmt Ar retransmission-timeout
|
|
Set the per-packet retransmission timeout, in seconds.
|
|
.Pp
|
|
.It Cm status
|
|
Show current status.
|
|
.Pp
|
|
.It Cm timeout Ar total-transmission-timeout
|
|
Set the total transmission timeout, in seconds.
|
|
.Pp
|
|
.It Cm trace
|
|
Toggle packet tracing.
|
|
.Pp
|
|
.It Cm verbose
|
|
Toggle verbose mode.
|
|
.El
|
|
.Sh BUGS
|
|
Because there is no user-login or validation within
|
|
the
|
|
.Tn 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.
|
|
.Pp
|
|
Files larger than 33488896 octets (65535 blocks) cannot be transferred
|
|
without client and server supporting blocksize negotiation (RFC1783).
