Net::TFTP - TFTP Client class
$tftp = Net::TFTP->new("some.host.name", BlockSize => 1024);
$fh = $tftp->get("remotefile");
$fh = $tftp->put("remotefile");
$err = $tftp->error
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
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"
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
A sub-class of IO::Handle
A tied filehandle
A GLOB reference (eg \*STDOUT)
Put a file to the server as REMOTE_FILE. OPTIONS can be any that are accepted by new plus the following
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.
If there was an error then this method will return an error string.
Set or get the values for the various options. If an argument is passed then a new value is set for that option and the previous value returned. If no value is passed then the current value is returned.
Set or get which verion of IP to use ("v4" or "v6")
Set the transfer mode to "netascii"
Set the transfer mode to "octet"
