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.

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. See tftpd(1M) for details about customizing
file-access restrictions on IRIX.
