SYNOPSIS
use Net::TFTP;
$tftp = Net::TFTP->new("some.host.name", BlockSize => 1024);
$tftp->ascii;
$tftp->get("remotefile", "localfile");
$tftp->get("remotefile", *STDOUT);
$fh = $tftp->get("remotefile");
$tftp->binary;
$tftp->put("localfile", "remotefile");
$tftp->put(*STDOUT, "remotefile");
$fh = $tftp->put("remotefile");
$err = $tftp->error
DESCRIPTION
"Net::TFTP" is a class implementing a simple Trivial File Transfer Protocol client in Perl as described in RFC1350. "Net::TFTP" also
supports the TFTP Option Extension (as described in RFC2347), with the following options
RFC2348 Blocksize Option
CONSTRUCTOR
new ( [ HOST ] [, OPTIONS ])
Create a new Net::TFTP object where HOST is the default host to connect to and OPTIONS are the default transfer options. Valid options
are
Option Description Default
------ ----------- -------
Timeout Timeout in seconds before retry 5
Retries Maximum number of retries 5
Port Port to send data to 69
Mode Mode to transfer data in, "octet" or "netascii" "netascii"
BlockSize Negotiate size of blocks to use in the transfer 512
IpMode Indicates whether to operate in IPv6 mode "v4"
METHODS
get ( REMOTE_FILE [, LOCAL ] [, OPTIONS ])
Get REMOTE_FILE from the server. OPTIONS can be any that are accepted by "new" plus the following
Host Override default host
If the LOCAL option is missing the get will return a filehandle. This filehandle must be read ASAP as the server will otherwise
timeout.
If the LOCAL option is given then it can be a file name or a reference. If it is a reference it is assumed to be a reference that is
valid as a filehandle. "get" will return true if the transfer is successful and undef otherwise.
Valid filehandles are
o A sub-class of IO::Handle
o A tied filehandle
o A GLOB reference (eg "*STDOUT")
put ( [ LOCAL, ] REMOTE_FILE [, OPTIONS])
Put a file to the server as REMOTE_FILE. OPTIONS can be any that are accepted by "new" plus the following
Host Override default host
If the LOCAL option is missing the put will return a filehandle. This filehandle must be written to ASAP as the server will otherwise
timeout.
If the LOCAL option is given then it can be a file name or a reference. If it is a reference it is assumed to be a valid filehandle as
described above. "put" will return true if the transfer is successful and undef otherwise.
error
If there was an error then this method will return an error string.
