Proxy IP to real IP conversion

[Paul M]

vBulletin 3.7 Version
Please remember to click Mark as Installed if you use this modification.
Support questions from members who have not marked this as installed will be considered low priority.

This hack makes the forum always use the members real ip when a proxy is detected, meaning that all existing ip functions should continue to work, basically ignoring the proxy server (other than recording it's presence).

i.e.

* The real ip (or host) is displayed in the who's online page.
* The real and proxy server ip's are accesible for each post, the button is red for members using a proxy server.
* The real ip is searchable in the admin/mod cp (but not the proxy ip).
* The real ip can be banned by admins.

etc etc ......

Note: Obviously this hack relies on the proxy server passing the correct http variables to allow detection.

If a proxy is detected, then a red ip icon is displayed instead of the standard one. This mod will also detect if the ipinfo hack is installed and adjust itself to call the ipinfo code.


History:

v3.7.001 : Initial release for vbulletin 3.7 beta.
v3.7.002 : Fix px.gif - Update install data for 3.7.
v3.7.003 : Installation Code Updated.


Remember that this modification involves changes to the class_core.php file - if you upgrade your vbulletin, you must reapply those changes.

[Snake]

Good to see this useful hack back again for 3.7 compability. Well done, Paul.

[kaptanblack]

Thanks...

[apiasto]

reserved but i am surprise y they didn't make this default in v bulletin,thnx for your work paul

[SwollenCranium]

Nice !!

I'll wait till gold before adding though.

[LewisAinslie]

Yeh, default in vb would of been a nice feature!
Especially with the vast ammount of proxies about these days.

[yahoooh]

thanks

[Ba$im]

thanx.

[ssvp]

I think there is a problem with the px.gif I just downloaded it and it has dimensions of 3349x3345 and when opened says, "Drawing Failed".

[Paul M]

I think you're right, I just tried and got the same. I've updated it.

[ssvp]

Yup worked like a charm.. Thanks Paul!

[phonexpo]

Will install when vbulletin 3.7 is released fully.

Thanks

[jaycob]

this hack just simply does not work on my forum, i just logged in using a proxy and posted and stuff and my ip did not turn back to my real ip.

[Paul M]

As the notes say ....

Note: Obviously this hack relies on the proxy server passing the correct http variables to allow detection.

[Spinball]

Good work, Paul. Does this version work with 3.6? (Can you please add a note in post #1?)

[Paul M]

Nope, this is the 3.7 version. There are seperate releases for 3.0, 3.5, 3.6 and 3.7

[jaycob]

As the notes say ....

ahh ok so its working but i havent used to right proxy detect?

[Paul M]

More and more proxy servers these days do not pass on the required variables. Unfortunately there is nothing that can be done about them.

[RaceJunkie]

How well does this work for AOL users? Will their Ip's be detected?

[Paul M]

As I recall, AOL proxy servers do not pass on the details.

[samraz972]

Parse error: syntax error, unexpected ')' in /home/globald5/public_html/forum/includes/class_core.php on line 1722

I keep getting that error

[Paul M]

Then you have not edited the file correctly. Start again.

[hornstar1337]

Just wondering, is this a fairly generic way of detecting proxies, or could you extend this, and take a look at proxies manually that are currently not being detected and get them to be detected in a future update?

[J98680B2423E]

Thanks Paul, *Installed* :up:

[rapidphim]

Paul, thanks for the Mod. However, how do I know/find out the use of this mod? I already installed it but don't know where to see the use of it.

anyone knows how to use this mod?

Thanks much for the help. However, where your normally see the Red IP Icon (assume there is one proxy IP)? Do you see it when viewing "Currently Active Users" or in AdminCP (where)

[Paul M]

In posts (only).

[rapidphim]

That I'd like to know. Thanks so much Paul.

Hello,
Please help me understand "what it do..?"

I have just instaled this mod in my board, but when i tryed to post some post using http://anonymouse.org , my messages have still 'anonymous.org' IP adress. I can`t see a 'proxy icon' anywhere.

Maybe there is some options in ACP to activate this hack? I have just changed class_core.php file and imported icon and product.
Maybe i did sth wrong?

My real IP (193.26.131.*) is visible when i posting without using anonymous.org.

PS. I`m not sure it have a matter, but month ago i have another problems and someone tells me i have to edit postbit_legacy (not postbit), because something.. ? :P

Hi Paul,i'm wondering if it possible to use this hack together with Check Proxy RBL on New User Registration. ?

Anonymous proxy servers do not pass on any such details for pretty obvious reasons, they wouldnt be very anonymous if they did.

Getting a blank page after doing the class core revisions.

That's the revised version that ends up with a blank page.

You overwrote the closing bracket of function fetch_ip() when you edited the file.

[bbqchef33]

so this will NOT work with Hidemyass, makemeaninja, etc..??

the anonymous proxies dont pass the proper info?

[Paul M]

I have no idea what Hidemyass, makemeaninja are, but no, annonymous proxies do not pass on the information - they wouldnt be very annonymous if they did. :)

[TheInsaneManiac]

The 3.6 version worked for 3.7, why the need for a 3.7 version?

[War_force]

thanks a lot

[Leo Brazil]

Installed and working good. Tks.

May be here is not the right channel for asking this but I'm sure who's using this mod might be interested in that too. Is there a way to block new registers if they are using annonymous proxies ?

[TroyTrojansFan]

Does anyone have a screenshot so I know what to look for to see if the mod is working properly? :)

[Angel-Wings]

Is there a way to block new registers if they are using annonymous proxies ?

Oh - believe me - that's a pure waste of time. That module requires that a proxy uses the HTTP_X_FORWARDED_FOR variables which some proxies do, others not.
By reading that variable it's possible to find the real IP but with a Webserver Module - at least for Apache, dunno about others, you can do the same.
Just - point is - just do a Search in your favorite Search Engine for "anonymous proxies" and you'll find a lot of them, most of them are non working. Problem is just that having a blocklist you need to update to add or remove proxies, well, a waste of time.
I just want to say that it's nearly impossible to block all proxies without a false positive and we shouldn't forget that there're still countries in this world which block sites - these people need proxies to bypass any filters to access the web freely.

What works for spam filters in blacklisting dynamic IP's doesn't make sense everywhere else - sorry

[chadi]

Are file changes needed to be done *again* to simply upgrade this module to the latest version?

[Paul M]

If you are referring to the update today then no, just the product xml was updated slightly (to detect the 3.7 version of ipinfo as well).

[chadi]

Thank you for clarifying.

I was trying that mod and was getting the same conclusion of yours. When I saw your comments here sound like a spark for me. That's true.

I have tow questions:
1- is there anyway to know if work or not?
2- does this mod have any issue with this one here:
http://www.vbulletin.org/forum/showthread.php?t=179362

[Angel-Wings]

1- is there anyway to know if work or not ?

Just try to access your board with different proxies ;)

[Paul M]

Bear in mind that not many proxy servers pass on these details now.

JFYI, this was originally written for Cable Forum four years ago because the UK ISP that our forum is about (ntl as was, now called Virgin Media) used to force all its customers to browse via transparant proxy servers that did pass on these details. This is no longer the case but I have continued to maintain it anyway. Its quite likely that when vb4 comes out I will probably not bother porting it anymore.

[skywalker2208]

Is there any proxies that this is known to work for because I have tested it and I don't find one that seems to make it work. I know you said that it has to pass the right info. I have tried like 6 or 7 proxies.

[TheInsaneManiac]

Do we have to do the file edits? For some reason it still seems to work even though I have not edited any files.

I still think you should port it. Most proxy websites like proxy.org, uses the same methods you are talking about, and I have caught many members who I have banned and they have made second accounts.

It cannot possibly work unless you edit the file.

i get this error..

You would not be able to measure any difference.

[thestaton]

Paul,

I installed PL2 this morning, and then this mod. I followed your instructions exactly how you have them. When I went to install / import the product, the system was hanging... I've had this happen once before with a theme, and I found that if you hit back and then try to reinstall it again very quickly that it will go through.

The problem I ran into, is I got a DB Error. If I go to the products pay it says it's installed... So I'm curious what i can do to test to see if it's working. Or if I should uninstall / reinstall.

Thanks for the help,

[Paul M]

If you have a very large Post table then it may seem to hang for quite a while as this adds a field to that table. If its installed, and seems to be working then probably best to leave it as is. You could check the Post table to see if the proxy_ip field has been added ok.

[thestaton]

Paul,

It's there. Thanks for the mod & thanks for the support.

[jailer]

Works great. I can see my real IP in 'Who's Online'. The px.gif doesn't show in posts for the reason Paul explained. My main concern is keeping real IP's banned, and this will do the trick just fine.
Thanks Paul.

[PoetJA-1975]

Thanx PAUL! Question though - Do you know of a proxy site where I can test?
Thanx,

JAcquii.

[Paul M]

Sorry, I dont.

[mmm3]

Does it work for guest posters using anonymous proxies, or only registered members?

[Paul M]

It wont work for annonymous proxies at all, otherwise they wouldnt be very annonymous. :)

[PoetJA-1975]

Sorry, I dont.

No probs - Thanx for responding. Can I ask you to please look at THIS THREAD (http://www.vbulletin.org/forum/showthread.php?t=184921) and offer a possible solution to the issue reported please?

[PoetJA-1975]

OK - so I tested this mod using http://proxy.paradox-productions.net
1st I tried browsing my own profile via the proxy site - see the pic below:

http://img174.imageshack.us/img174/779/ipbq2.gif


I suppose in the Who's Online page - the px.gif graphic doesn't show.
The interesting thing is that the proxy IP showed up - My IP address did not show on the Who's online page. So then - I tested by posting in the JPiC Staff Zone.... The px.gif graphic didn't show either and clicking on the regular IP graphic showed an IP address of 77.243.225.164 - circe.xynta.nl --- instead of my own IP address

So - question. What have I done wrong? I had expected that my IP address would show on both accounts. Am I misunderstanding what this modification does?

Thanx,

Jacquii.

[Paul M]

px.gif is not meant to appear in the WOL page. It appears in the postbit.

Also, please read the notes in the main post re detection.

[PoetJA-1975]

OK - so basically your saying what...? :P
Thanx for commenting too - and thanx for sharing the modification.

I had some problems with this, it would always record the real IP as the proxy ip as well

this fixed it for me:

Replace:
return $real_ip;
with:
if($real_ip != $_SERVER['REMOTE_ADDR']) return $real_ip;

[lowlight]

Hmm, when I spot someone who is apparently using a proxy, and go to get their info, it just says:



Code:
---------------
Code is only visible to licensed users, and only when logged into the forums.
---------------



Is it not able to find proxy IP addresses?

Thanks for this BTW!

Thank you VERY much!

I guess the only thing more I could want from this would be a diff against 3.7.3PL1 that I could simply run 'patch' on. :D

[Come2Daddy]

Actually I tryed to install it but I didn't find some codes you mentioned in the class core

[harlita]

Come2Daddy - depending on the HTML/PHP editor you are using, the find-function is likely not searching the entire document from top down with each find request. And that can easily throw a person off.

In otherwords, you likely were able to complete Step 1, but once you got to Step 2, it couldn't find the code you entered in.

If that is the case, try going thru it again, but after you complete Step 1, scroll back up to the very top and physically click on the first line of the file. Once you see the cursor flashing there, try the search for the code in Step 2 again.

I'm running 3.7.3 forums (few of them XD) and this code works as a brand new install (not sure how I overlooked it prior).

Thanks Paul M :) Another great job.

[Come2Daddy]

Thanx Harlita

actually I followed your instructions and it worked just fine, however I didn't notice any difference after I installed this hack

Suggestion: ignore LAN ranges, such as 192.168.x.x or 172.x.x.x

Within the file edits you will find a line that says ;

Change that to true and it will exclude those private ranges.

[Warden-B-]

They do exist and they came with these styles. They are attached.

[Paul M]

Like I said, px.gif is not a standard vb image/file, I cant imagine why those styles would have one, the only time they would get used is if you have this mod installed. Perhaps they were created for someone who originally did.
