Title : Anti-Leech Attachments

Version : 1.1

Coder : Jason Williams

Purpose : Prevent your forum attachments from being directly linked to - prevent bandwidth abuse.

Why : Bandwidth can be expensive, plus I was frustrated with one of my members linking to three video clips on my forum from his own site, effectively abusing the bandwidth I pay for, so I set about a system that stops hotlinking, but at the same time, as a courtesy, providing a dynamic link to the post containing the attachment.

How : This could be replicated very easily using .htaccess but the one thing that it can't do is give you the link to the attachment itself. This mod displays a message informing the user that hotlinking is not allowed, then giving them the link to the post to view the attachment directly.

Known Issues : The security can be defeated by using the drop down style menu on the Anti Leech page - this has only been confirmed as an issue on Firefox. I have unsucessfully tried to find a way of removing the drop down on that page only.

Confirmed working with vBSEO 3.2.0.

Important : This has been tested on 3.6.2 and 3.8, I can presume it will be compatible with 3.7.x because it works on 3.8 - as always BACKUP FIRST!

Demo : http://www.steadiforum.com/attachmen...9&d=1180779148

Installation :

1. Import Product - product-antileech.xml
2. Save bandwidth!

File uploads : 0
Files to Import : 1
New Templates : 1
New Phrases : 2
Uses Hooks : 1
Uses Queries : 1

History :
v1.0 - Original release

v1.1 - Added enable/disable option, tested on VB 3.8

Done - if you like please click install! (and click Nominate for MOTM!)

Sorry guys, been out of the loop for quite a while now, will take a look at this and see if anything needs updating, I have tested it on my current install and it works fine.

[Update]

Tested on vb 3.8.0 - click to test -- http://www.steadiforum.com/attachmen...2&d=1222457106

Could you confirm which version of vb you are attempting to run this on? I will re-investigate the admincp issue, there should be the option there.

Thanks,

Jason

Works perfectly on my forum - VB 3.8.2 with VBSEO

Only problem that still remains is with people with no referer entry (ie they have antivirus programs like Norton which remove the referer tag for no apprant reason). A fix that would also allow people with no referer to download to would be brilliant.

Installed, much appreciated

Installed on my 3.8.3 board, but does not work and there is no option in vB Options either. I tried replacing the plugin code as an earlier poster suggested, but it still does not work.

thanks. there is a mod like this but to do this with the images displayed in a forum? is that if someone copies the address of an image to put in another forum, this will not show any image and leave another pic in place? thanks

I just copied the address and posted that pic in my forum using image tags with no problem, which is what I thought this was supposed to prevent?

Not sure I understand the use of this, at all?

kalisekj · #80 09-30-2009, 04:36 PM

I am still able to hot link to my attachments

I tested it using the demo pic and hotlinked it from there, so I don't think it's just you.
