Net::SFTP::Foreign password authentication error

Question

I'm running the following script to connect to a sftp:

#!/usr/bin/perl
use strict;
use warnings;
use POSIX;
use File::Path qw(make_path);
use File::Copy;
use IO::Handle;
use IO::File;
use Data::Printer;
use Net::SFTP::Foreign;
$Net::SFTP::Foreign::debug = -1;

STDOUT->autoflush(1);
STDERR->autoflush(1);

my ($genCfgFile) = <@ARGV>;

if (!defined($genCfgFile)||($genCfgFile eq '')){
    print "Usage: $0 cfgFile";
    exit(1);
}

my %User_Preferences=readCfgFile($genCfgFile);
    print p(%User_Preferences)."\n";
getFilesFromSFTP(\%User_Preferences);

exit(0);

sub getFilesFromSFTP{
    my ($User_PreferencesHref)=@_;
    my $FtpHost=$User_PreferencesHref->{"FTP_HOST"} or die "Missing parameter FTP_HOST in cfg file.\n";
    my $FtpPort=$User_PreferencesHref->{"FTP_PORT"} or die "Missing parameter FTP_PORT in cfg file.\n";
    my $FtpUser=$User_PreferencesHref->{"FTP_USER"} or die "Missing parameter FTP_USER in cfg file.\n";
    my $FtpPwd=$User_PreferencesHref->{"FTP_PWD"} or die "Missing parameter FTP_PWD in cfg file.\n";

    my %args = (user => $FtpUser, password => $FtpPwd, port => $FtpPort);

    print p(%args)."\n";

    my $sftp= Net::SFTP::Foreign->new($FtpHost, %args) or die "Cannot connect to : $@";
    my $entries = $sftp->ls;
    print p(@$entries)."\n";
}

However, it somewhat fails during the password autenthication, this is the debug log:

I'm using IO::Pty v 1.12 and Net::SFTP::Foreign 1.77, can anybody help me?

Answer 1

This is your problem:

Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

Your login isn't being accepted. Can't tell you why, because it's a server side error. Diagnostic steps might include: running sftp by hand, and verifying that the username/password can in fact, log in to the sftp server and run an 'ls'.
