cannot login into SFTP server using Net::SFTP

hi

we're using Public/Private Key authentication between SFTP client and server to trnasfer files.
I can login into SFTP server from my client linux debian machine without problems using this command:

# sftp user@server (without password)

but if i try to use a Net::SFTP perl script it doesn't work:

Code:

#!/usr/bin/perl -w

use strict;
use warnings;

use Net::SFTP;

my $server="X.X.X.X";

my $user="myuser";

my $password="";

my %args = (user => "$user", password => "$password", ssh_args => [port => 22]);

my $file="TEST.CSV";

my $sftp=Net::SFTP->new($server, %args);

$sftp->put($file);

exit;

TEST.CSV is there, at the same directory.

I get the following error:

Code:

# perl test.cgi
Use of uninitialized value in concatenation (.) or string at /usr/local/share/perl/5.8.8/Net/SFTP.pm line 245.
Couldn't get handle: No such file or directory at test.cgi line 20

howto solve this problem ?

A few things occur to me:

1. the '-w' switch and 'use warnings;' do the same thing (FYI), so only 1 is reqd.

2. you're not checking for errors at all eg calling the new and put methods.

3. The cpan page says this pm is only good for SSH v2 protocol. (Net::SFTP is a pure-Perl implementation of the Secure File Transfer Protocol (SFTP) - file transfer built on top of the SSH2 protocol.)
Are you sure you systems are using this.?

4. the cpan page also seems to show that the remote filename is not optionalk in the put method eg: $sftp->put("bar", "baz");
