I am trying to implement a secure FTP transfer to a remote machine. The remote machine does NOT permit an SSH telnet session, but will allow SFTP sessions. I am able to connect using the command line 'sftp'. However when connecting to the same machine using Net::SFTP I get the following error messages:

local: Connecting to ***********, port 22.
local: Remote protocol version 2.0, remote software version OpenSSH_3.0.2p1
local: Net::SSH::Perl Version 1.23, protocol version 2.0.

Permission denied at /opt/perl/lib/site_perl/5.6.1/Net/SFTP.pm line 37

Line 37 of SFTP.pm is:

$ssh->login($param{user}, $param{password});

The remote SFTP host uses public/private keys and only needs a username (ie. user@host) to login - all of which is in my code:

use Net::SFTP;
my %args = (ssh_args => []);
$args{user} = $user;
push @{ $args{ssh_args} }, port => 22;
my $sftp = Net::SFTP->new($host,%args);

Any ideas what the problem might be?
