NET::FTP: ls command fails

[esskar]

Hi, i'm trying to setup a ls command using Net::FTP. First, i show you my code

my $ftp = Net::FTP->new( $row->{ftp_host}, Debug => 1)
 or die "Cannot connect to " . $row->{ftp_host} . ": $@";
     
$ftp->login($row->{username}, $row->{password})
 or die "Cannot login ", $ftp->message;
                       
$ftp->cwd("/logs/web")
 or die "Cannot change working directory ", $ftp->message;
     
$ftp->pasv;    
     
my @dir = $ftp->ls; # <-- LINE 50

the trace looks as follows:

Net::FTP: Unexpected EOF on command channel at getenomlogs.pl line 50

I googled abou the 'Unexpected EOF on command channel' error, and it seems to be a aktiv <=> passiv FTP problem. But i already did entering passiv mode (i also have to check this option in my ftp client to get a proper connection) but why is Net::FTP setting up a PORT command - isn't that the command for establishing an aktiv connection?

Does anybody know what to do?
