NAME

TFTP - TFTP Client class

SYNOPSIS

     use TFTP;
 
 

     $tftp = new TFTP("some.host.name");
     $tftp->get("that.file");
     $tftp->octet;
     $tftp->put("this.file");
     $tftp->quit;
 
 

DESCRIPTION

"TFTP" is a class implementing a simple TFTP client in Perl as described in RFC783.

OVERVIEW

TFTP stands for Trivial File Transfer Protocol.

CONSTRUCTOR

new (HOST [,OPTIONS])

This is the constructor for a new TFTP object. "HOST" is the name of the remote host to which a TFTP connection is required.

"OPTIONS" are passed in a hash like fashion, using key and value pairs. Possible options are:

Port - The port number to connect to on the remote machine for the TFTP connection

Mode - Set the transfer mode [NETASCII, OCTET] (defaults to NETASCII)

Timeout - Set the timeout value before retry (defaults to 2 sec)

MaxTimeout - Set the maximum timeout value before retry (defaults to 8 sec)

Retries - Set the number of retries (defaults to 3 with arithmetic backoff)

METHODS

mode (TYPE)

This method will set the mode to be used with the remote TFTP server to specify the type of data transfer. The return value is the previous value.

netascii, ascii, octet, binary

Synonyms for "mode" with the first argument set accordingly

get ( REMOTE_FILE [, LOCAL_FILE ] )

Get "REMOTE_FILE" from the server and store locally. "LOCAL_FILE" may be a filename or a filehandle. If not specified the the file will be stored in the current directory with the same leafname as the remote file.

Returns "LOCAL_FILE", or the generated local file name if "LOCAL_FILE" is not given.

put ( LOCAL_FILE [, REMOTE_FILE ] )

Put a file on the remote server. "LOCAL_FILE" may be a name or a filehandle. If "LOCAL_FILE" is a filehandle then "REMOTE_FILE" must be specified. If "REMOTE_FILE" is not specified then the file will be stored in the current directory with the same leafname as "LOCAL_FILE".

Returns "REMOTE_FILE", or the generated remote filename if "REMOTE_FILE" is not given.

quit

Close the current socket and release any resources. A more complete way to release resources is to call 'undef $tftp;' on the session object.

REPORTING BUGS

When reporting bugs/problems please include as much information as possible. It may be difficult for me to reproduce the problem as almost every setup is different.

A small script which yields the problem will probably be of help. It would also be useful if this script was run with the extra options "debug =" 1> passed to the constructor, and the output sent with the bug report. If you cannot include a small script then please include a Debug trace from a run of your program which does yield the problem.
