perl ftp and hidden partitions

Hi all

I have an automation problem with perl and a ftp server.
The server is running on a B&R-SPS. This contains a flash memory (2GB)
for data logging.
The files will be on a hidden partition called "F".

I tried to log in on different ways:
e.g.:

my $ftp=Net::FTP->new($host,Port => 21, Debug => 1, Passive => 1) or
die "Couldn't connect: $@\n";
print "Connected\n";

$ftp->login('br','br',"/F:/") or die $ftp->message;
my $type = $ftp->binary;
my @files = $ftp->ls();
foreach (@files)
{
print "$_\n";
}
$ftp->quit;
print "closed ftp connection\n";

The problem is that I can login, but get only the file list of
partition "C", which isn't a hidden one. So I don't know
how I can login into the hidden partition with perl

Best thanks for any help

Just what does "hidden" mean in this context? Does it perhaps mean
"unlistable"? If so what did you expect?

Have you tried just getting the files (by full name)?

That third argument looks odd - the Net::FTP docs call it "ACCOUNT," which
implies that it will (if provided) cause the client to issue the FTP command
of the same name, which has nothing to do with establishing a working dir
for the session.

You can see the description of the ACCOUNT command here:

<http://www.faqs.org/rfcs/rfc959.html>

Have you tried logging in without the third param, and then using the cwd()
method to change to the drive & directory you want? Something like this:

$ftp->login('br','br') or die $ftp->message;
$ftp->cwd('/F:/') or die $ftp->message;

Thank for all this tips.
I figured out that
$ftp->login('br','br') or die $ftp->message;
$ftp->cwd('/F:/') or die $ftp->message;

works, but not each time. So I think the error is not in my perl code!

I will check the ftp-server and some application code on the sps

thanks again to all the people answerd my question
