Link Anonymizer · **Released**: 09-05-2005

Link Anonymizer v1.02a & 1.03, 1.04, 1.05.3 & 1.10

Author: MarcoH64

vBulletin Version: 3.5.1

Warning: Version 1.02 might create double anonym links if you edit a post multiple times. Version 1.03 has been reported not to be working for some people. Please read posts in this thread if you plan on using this hack, until i had time to look into this.
v1.05 and higher should be the best versions
1.10 Is an updated version of 1.05.3 and is considered a stable release. Only version 1.10 will be supported now.

Description:
This Product will add a self configurable anonymising link to all external urls in posts.

Installation:
Install the XML-file as Product.

Configuration:
vBulletin Options->Link Anonymizer :

Local Addresses

Local addresses are not anonymized. If you leave this option blank, the value for vBulletin Options Cookie Domain will be used. Do not use a http:// prefix.

If you start the name with a dot (.mydomain.com) all server addresses ending with this will be considered local. If you want to add mulitple domain/servernames, seperate them by a single space.

Anonymizer (default: http://anonym.to/?)

Link to a anonymizer function. Use preceding / if needed. Other Usable Anonymizers:
Code:
http://anon.free.anonymizer.com/ 
 
http://anonym.webgurus.de (Thanks Wachtmeister)

Allways anonymize Unparseble URLs (* New in version 1.10)

Please click install if you are using this hack.

It is possible that there are still double links in the database from old versions. If you wish to remove these, run the following queries (make backup first!!):

SQL Query: (how to run queries)
update post set pagetext = replace(pagetext, "http://YOURANONIMIZERLINK/","");

Will wait to see if this is working good for everyone (did some more extensive testing this time). If all is ok, i will have a look at the feature suggestions.

@dasdingansich
You can configure what anonymizer you want to use, but maybe i should change the default if that one is too much limited.

I installed it but nothing seems to happen.

Could someone tell me where I could have gone wrong?

tokenyank · #77 10-26-2005, 07:21 PM

Marco, this seems much more robust than this one but I do not wish to use an external anon server like safeurl or whatever... Would/could this hack work using the links.php in the other hack for non-anon parsed url's?

Marco van Herwaarden · #78 10-26-2005, 09:01 PM

@tokenyank, i don't know, never looked at the other hack.

@Lord Brar
PM me MSN contact info and i will try to get in contact tomorrow.

tokenyank · #79 10-26-2005, 10:38 PM

In principal, it should work yeah? As safeurl works with a ?domain switch as does the other hack...

Hmm... I may play with it and find out for myself... Thanks anyway

1.You can use links.php, just config your anonymous site to your site.
Ex: http://www.xxx.com/links.php?url=
2. The hack you said is which I don't like because It modified the class_bbcode.php code, so when you upgrade to new version --> need to hack again.

Just to confirm, it does work, though using the settings in the AdminCP did not do anything... Almost as if they weren't saving...

I modified the xml to reflect what anon service I wanted to use though and reinstalled and it works fine!

Thanks... Installed
