PREPARE THE WEB SERVER
on your VPS/seedbox, run the following commands one after the other:
sudo apt-get install lighttpd
sudo apt-get install php5-cgi
sudo nano "" > /etc/lighttpd/lighttpd.conf
sudo nano /etc/lighttpd/lighttpd.conf
then copy and paste the following text into nano:
note: replace "djnitehawk" with your username
server.modules = (
"mod_access",
"mod_alias",
"mod_compress",
"mod_redirect",
"mod_auth",
"mod_fastcgi",
# "mod_rewrite",
)
server.document-root = "/home/djnitehawk/Ready"
server.upload-dirs = ( "/var/cache/lighttpd/uploads" )
server.errorlog = "/var/log/lighttpd/error.log"
server.pid-file = "/var/run/lighttpd.pid"
server.username = "www-data"
server.groupname = "www-data"
index-file.names = ( "index.php", "index.html",
"index.htm", "default.htm",
" index.lighttpd.html" )
url.access-deny = ( "~", ".inc" )
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )
## Use ipv6 if available
#include_shell "/usr/share/lighttpd/use-ipv6.pl"
dir-listing.encoding = "utf-8"
server.dir-listing = "disable"
compress.cache-dir = "/var/cache/lighttpd/compress/"
compress.filetype = ( "application/x-javascript", "text/css", "text/html", "text/plain" )
include_shell "/usr/share/lighttpd/create-mime.assign.pl"
include_shell "/usr/share/lighttpd/include-conf-enabled.pl"
auth.debug = 0
auth.backend = "plain"
auth.backend.plain.userfile = "/etc/lighttpd/pass.txt"
auth.require = ( "/" =>
(
"method" => "basic",
"realm" => "Password protected area... Get lost!",
"require" => "user=djnitehawk"
)
)
fastcgi.server = ( ".php" => ((
"bin-path" => "/usr/bin/php5-cgi",
"socket" => "/tmp/php.socket"
)))
save and exit nano by pressing CTRL+X and Y and enter.
and then run the following command:
sudo nano /etc/lighttpd/pass.txt
then copy and paste the following text into nano:
note: replace "djnitehawk" with your username and replace "A_STRONG_PASSWORD_FOR_YOUR_WEB_SERVER" with a strong password.
djnitehawk:A_STRONG_PASSWORD_FOR_YOUR_WEB_SERVER
save and exit nano by pressing CTRL+X and Y and enter.
and then run the following commands one after the other:
sudo chmod 777 /etc/lighttpd/pass.txt
sudo openssl req -new -x509 -keyout server.pem -out server.pem -days 36500 -nodes
at this point, it will ask you for some personal details. just enter the appropriate values for generating your own self signed SSL certificate. pay special attention when it asks for your "Common Name (e.g. server FQDN or YOUR name)". you have to enter your domain or subdomain name you have setup for your VPS/seedbox. i have not tried entering an IP address in this field, but you can try.
after the wizard finishes, run the following commands one after the other:
sudo chmod 777 server.pem
sudo mv server.pem /etc/lighttpd/
sudo lighty-enable-mod ssl
nano ~/Ready/index.php
then copy and paste the following text into nano:
note: replace "djnitehawk" with your username.
<?php
$src = "/home/djnitehawk/Ready";
$del = $_GET[delete](/delete);
$clean = $_GET[clean](/clean);
if (!empty($del)){
$file = "$src$del";
unlink($file);
echo "File Deleted: $file";
exit;
}
if (!empty($clean)){
if ($clean == 'yes') {
RemoveEmptySubFolders($src);
echo "Empty folders have been cleaned...";
}
exit;
}
$res = ListIn($src, "$src/");
echo implode('|',$res);
function RemoveEmptySubFolders($path)
{
$empty=true;
foreach (glob($path.DIRECTORY_SEPARATOR."*") as $file)
{
$empty &= is_dir($file) && RemoveEmptySubFolders($file);
}
return $empty && rmdir($path);
}
function ListIn($dir, $prefix) {
$dir = rtrim($dir, '\\/');
$result = array();
foreach (scandir($dir) as $f) {
if ($f !== '.' and $f !== '..' and $f !== '.lock' and $f !== 'index.php') {
if (is_dir("$dir/$f")) {
$result = array_merge($result, ListIn("$dir/$f", "$prefix$f/"));
} else {
$result[] = $prefix.$f;
}
}
}
return $result;
}
?>
save and exit nano by pressing CTRL+X and Y and enter.
and then run the following commands one after the other:
chmod 777 ~/Ready/index.php
sudo service lighttpd restart
that's all you have to do on your VPS/seedbox.
to verify that your newly installed web server is running with SSL, visit your VPS/seedbox in a web browser like so:
https://vps.mydomain.com
if everything works correctly, it should now prompt you for a username and password with some text like: "Password protected area... Get lost!" 
if it's not working, go back and double check your work. optionally try restarting your VPS/seedbox with:
sudo shutdown -r 0
PREPARE THE LOCAL COMPUTER
the following has to be done on your local ubuntu computer. if your local computer is a windows box, you can look into running ubuntu on a virtual machine (ex: http://www.virtualbox.org) until someone converts this whole recipe into windows.
ok, lets get started...
log into your local ubuntu box and run the followings commands one after the other:
sudo apt-add-repository ppa:t-tujikawa/ppa
sudo apt-get update
sudo apt-get install aria2
sudo apt-get install curl
cd ~/
nano downer
then copy and paste the following text into nano:
note: replace "djnitehawk", "FROM-SEEDBOX", "vps.mydomain.com", "A_STRONG_PASSWORD_FOR_YOUR_WEB_SERVER" with your information.

save and exit nano by pressing CTRL+X and Y and enter.
and then run the following command:
chmod +x downer
¶ that's it. the setup is now complete...
to test the download manager, first make sure that your VPS/seedbox has some files in the "~/Ready" folder.
then log in to your local ubuntu box and issue the following command to start downloading files from your VPS/SB server:
./downer
to cancel the downloading, simply press CTRL+C
to display a list of files that are on the VPS/SB in the "~/Ready" folder, simply run:
./downer list
to limit the bandwidth used up by the download manager, simply run:
./downer 100
the 100 above is to set the download bandwidth limit to 100 KB/s. to limit the bandwidth to 1 MB/s, use 1024 like so:
./downer 1024
¶ that's all there is to it... enjoy!!!
TIPS & TRICKS
to run the download manager in the background, so you can close/disconnect from your terminal session, use as follows:
screen -R x
./downer
at this point, you can either close your terminal session or detach from the download manager by pressing CTRL+A+D and it will still keep downloading your files from the VPS/SB.
to reconnect to an already running download manager, issue the screen command again like so:
screen -R x
