DLMan Pro 0.9.x
This script is a downloads management script that hooks into phpBB2
permissions and allows yet more integrated functionality to complement
Calendar (lite/pro) and the other mods I'm working on.
As with Calendar Pro this script is still very much in development
and will continue to be supported with the application of new features
and improved functionality.
- mySQL database (compatability with other DBMS's is being
- PHP 4.23 +
- phpBB2 installed (version 2.0.4)
Making Downloads Available
Providing downloads on a web site usually involves a link to a
file that exists somewhere in your public web space and as such
there's not a lot you can do to secure them, track who gets what,
etc... DLMan actually handles a lot of this by...
Making Downloads Secure...
Downloads provided through the DLMan system are stored in a location
that is not publicly accessible because the files are located in
filespace outside of your normal web space. Instead DLMan provides
a sort of front desk that checks your credentials and then passes
copies of the file(s) you want through to you. This forces your
users to actually validate themselves (unless you make your files
publicly accessible) before they can get anything.
Easy Maintenance of multiple File downloads
One of the main benefits of the DLMan system is that it allows
you to maintain multiple file packs without having to create your
own zip or gzip files and then upload EVERYTHING each time. It
does this by keeping a full set of the files you wish to include
in your pack in a sub-directory of you filestore. Then whenever
someone clicks on the appropriate download it creates the appropriate
pack as a single gzip or zip file on the fly.
So, instead of having to upload all the files when just one changes,
you simply upload the changed file to overwrite the old one, or
just add new files, delete defunct ones, etc... and the next person
to download the pack gets the new set as is. Simple!
Multiple Levels of Access
Because there will always be multiple levels of access for the
wide range of people accessing your downloads DLMan allows you
to specify restrictions for individuals categories (folders) of
download and you can add/alter access according to your particular
needs throughout. So, some files and folders can be open to all,
while others may be restricted to specific usergroups.
All DLMan code uses the phpBB2 templating system and theme css
values. This helps to ensure compatability and ease of customisation
in line with
various compliant phpBB2 themes. It also means that users can develop
their own template set and offer them as alternative layouts.
Thanks to excrutiatingly long experience in dealing with various
mods for phpBB2 I've been able to develop a system of upgrading
that mirrors (and
admittedly borrows from) the phpBB2's own installation
the exception of some small edits required in the original phpBB2
files, installation is relatively painless compared to many mods.
The overall script itself includes many more underlying
functions and features including the following:
- Logs of downloads, errors, trapped spoofing attempts, etc..
- Ability to download files in Gzip (tar.gz) and Zip archives
(to save on bandwidth and to allow Pack creation)
- Ability to specify whether native formats are allowed (eg:
full fat (non-compressed) word docs without zipping first)
- Optimised SQL queries to avoid loading a server too greatly
- Numerous sanity checks to ensure data is of the correct type,
cracker spoofing traps and variable restrictions to enhance security.
Development will continue to ensure that any security issues are
deal't with plus to ensure compatability with phpBB2 as it too
is upgraded and improved. In addition there are a number of additional
features that will be added as time allows to improve the functionality
of the system.
This mod is still a 0.9.x version so as per regular version numbering
this indicates that it's not a FULL product as I'd like to call
it... There is a lot of development work needed, particularly in
terms of usability and logging functionality... Overall, the mod
does a pretty good job of providing a secure environment for downloads
and makes my job a lot easier here on Snailsource.
