I'm developing a program to download some files from a vendor site. The site uses FTP with SSL. I can connect but my data connections are dropped. I think that the module is not allowing encryption on the data channel. I tested with lftp and my data connections (e.g. and ls command) only worked after I enable encryption on the data channel. Yes, the ls returns files and directories.

#!/usr/bin/perl

use strict;
use warnings;
use Net::FTPSSL;

my $server = "ftps.example.com";
my $username = "*********";
my $passwd = "**********";

my @ret;

my $ftps = Net::FTPSSL->new( $server,
    Debug => 1)
    or error("Cannot reach $server");

$ftps->login($username, $passwd)
    or error("Credential error, $ftps->last_message");

@ret = $ftps->list()
    or error("Command error, $ftps->last_message");

$ftps->pwd();

print @ret;
