This is disgusting, but it's a just a quick-n-dirty hack to upload a directory structure to a remote FTP server where the FTP server would only allow one "put" command per login session. Yes, really. Obviously there was no ssh access otherwise I would have used rsync/scp -r. Oh well.

#!/usr/bin/perl 

use warnings;
use strict;
use Net::FTP;
use File::Basename;


my $startdir = "somewhere";
my $ftphost  = "somehost";
my $ftpuser  = "someuser";
my $ftppass  = "somepass";

upload_dir($startdir);

sub upload_dir {
    my $dir = shift;
    foreach my $entry (<$dir/*>) {

            upload_dir($entry) if(-d $entry);

            my $ftp =  Net::FTP->new($ftphost)
                or die "Can't connect to $ftphost: $@";
            $ftp->login($ftpuser, $ftppass)
                or die "Can't login ", $ftp->message;
            my $dirname = dirname $entry;
            $ftp->mkdir($dirname, 1);
            $ftp->cwd($dirname);
            $ftp->put($entry);
            $ftp->quit;
    }
}
