uDownloadTM Online File Distribution Manager
uDownloadTM is a system that manages electronic file distribution and file downloading via the Internet. With uDownload, you can control the downloading of all types of files such as pictures, artwork, music files, movies, recipes, building plans, software, documents... virtually anything that you want to distribute electronically.
The Features of the uDownloadTM include:
uDownloadTM consists of one Perl CGI script. System requirements are:
uDownloadTM consists of one Perl script that must be configured and installed on your web server. To configure the script, you will need to open it with any standard text editor - such as NotePad or WordPad - and answer the eleven (11) questions at the top of the script.
If you've never installed or executed any Perl scripts on your web server before, it is strongly recommended that you first try installing our basic test script as described on the following reference page:
By installing this basic Perl script, it should help you to understand how to install and execute scripts on your web server. It also will verify that your web hosting account is configured properly to run Perl scripts and will make installing the uDownloadTM script that much easier.
1. What is the path to perl on your web server?
The uDownloadTM script is written in the Perl programming language,
which is a standard on most web servers. In order to run this Perl script, you must
specify the location of perl on your web server. If you do not know the path to Perl on your web server, ask your web-hosting
Note: The path to perl should be specified as the very first line at the top of the script and should include the #! characters in front of the path.
On UNIX servers, typical values are:
On Windows servers, typical values are:
2. What is your uDownload License Number?
For this question, simply enter the license number that you were given when
purchasing uDownload. An example value is:
$license_number = "ABC-123-456-789";
3. What is the URL of your website?
this question, simply enter the full URL of your website. An example value is:
$domain = "http://www.mydomain.com";
4. What is the URL of this script?
The $script_url parameter must be set to the full URL of the script on your
web server. For example, if you put the script into your cgi-bin directory, then you
should set this value to something like:
$script_url = "http://www.mydomain.com/cgi-bin/udownload.pl";
Note: Some servers require that CGI scripts end with .pl and other servers require that scripts end with .cgi. Remember that if you have to rename the script to use the .cgi file extension instead of the default .pl file extension, then be sure to use udownload.cgi instead of udownload.pl in this parameter.
5. What is the full or relative path to your download data directory?
As part of the installation of this uDownloadTM script on your web server (which is described in the next section), you will need to create a "download data" directory on your web server. This "download data" directory is where uDownloadTM will store all of the downloadable soft goods and download data files. Typically, this "data" directory should be created as a subdirectory of your "cgi-bin" or "cgi-local" directory .
In order to be able to write files to the download data
directory you must specify the path to that directory on your web server. This path
can be specified as a relative path - relative to the location of
the script in your CGI directory - or as the full path to the
directory from your root directory. (If you want to use the full path to your
directory, you may need to ask your web-hosting provider what the full path to
your directory is. This value is NOT your URL and should NOT begin with
An example of a relative path (from your cgi-bin to your download data directory) would be:
$download_directory = "./downloads/";
An example of a full path (directly to your download data
directory) would be:
$download_directory = "/www/youraccount/cgi-bin/downloads/";
...on UNIX servers, or perhaps something like this:
$download_directory = "C:/users/youraccount/cgi-bin/downloads/";
....on Windows Servers.
This is a directory path, not a URL. So it won't start with "http". If you don't know the full path to your cgi-bin directory, then ask your web-hosting provider.
6. What is the e-mail address of the administrator?
This should be the e-mail address of the person who will mainly be in charge of the file distribution system (the uDownloadTM administrator)
An example value for this parameter would be something like:
$admin_email = 'email@example.com';
7. What e-mail method do you want to use? (SENDMAIL, SOCKETS, or CUSTOM)
In order to take advantage of the e-mail notifications or other e-mail utilities,
you must configure the e-mail method you would like to use. With the $email_method
parameter you can specify "SENDMAIL", "SOCKETS", or
For UNIX servers, it is recommended to use sendmail. (Sendmail is an e-mail utility that is standard on most UNIX servers). To use sendmail, set this parameter to:
$email_method = "SENDMAIL";
For Windows Servers, you must use SOCKETS or CUSTOM:
$email_method = "SOCKETS";
$email_method = "CUSTOM";
8. If using SENDMAIL in question #7 above, what is the path to sendmail?
In order use sendmail to send e-mail, you must specify the
location of sendmail on your UNIX server. Typical locations of sendmail are
/usr/lib/sendmail, /usr/bin/sendmail, or /usr/sbin/sendmail. If you do not know
the location of sendmail on your web server, you can ask your web-hosting provider
for the path to sendmail.
An example setting for this parameter is:
$sendmail_path = "/usr/sbin/sendmail";
If you specified question #7 as "SOCKETS" or "CUSTOM", then you can skip this question.
9. If using SOCKETS in question #7 above, what is the IP address (or name) of you mail server?
In order to send e-mail via SOCKETS, you must specify your mail server either by name (such as postoffice.mydomain.com) or by IP address
(such as 123.456.789.0). If you do not know the name or IP address of your mail
server, you should be able to ask your web-hosting provider.
An example setting for this parameter is:
$smtp_address = "123.456.789.0";
If you specified question #7 as "SENDMAIL" or "CUSTOM", then you can skip this question.
10. What password would you like to use for the uDownload administrator?
For this question, specify any password that you would like to use when logging in to uDownload’s Control Panel. You can use almost any combination of letters and numbers for the password. An example value is:
$admin_password = "mypassword";
11. What password would you like to use for external interfaces to uDownload?
If you are using optional external interfaces to uDownload use the interface parameter password. An example value is :
$interface_password = "survivor";
Note: Question #11 is not used unless you are going to be utilizing a 3rd party interface to your uDownload script. However, even if not using it, it is recommended that you should still specify a password here, for security purposes.
After editing/configuring the script, as described in the previous section, you will need to install the file in the CGI directory on your web server. To do this:
After following the above steps to install uDownloadTM
on your web server, you can test that the CGI script is setup correctly by opening
your browser and typing the full URL of the script on your web server into the
LOCATION box on your browser. This URL should be the same URL that you specified
in question #4 of the script setup, such as:
Upon doing so, you should see uDownload Login Form, similar to when you go to
the URL script on Microburst's website:
If when going to the URL of the script on your web server you get a "Server Error" instead then something is not setup correctly, see the Troubleshooting section below.
In order to keep the troubleshooting information as up-to-date as possible, we have moved this Troubleshooting section to the uDownloadTM online reference site at:
