Proxy IP to Real IP Conversion

[Paul M]

This modification is no longer available.

The latest vBulletin 3 version (3.8.11) has the same built in system as vB 4.2, that system should be used instead.


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).

For example ;

* 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.

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:

v3.8.001 : Initial release for vbulletin 3.8.


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

Thanks Paul Installed :up:

[bleros]

thnx Paul installed

[GrendelKhan{TSU]

yay!! been waiting for this. thank you!! :D :D

[Brother Malachi]

How reliable is it?

[Paul M]

Read the first post.

[Brother Malachi]

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

How reliable is it? How many proxies actually pass the correct http variables to allow the detection?

[Angel-Wings]

How reliable is it? How many proxies actually pass the correct http variables to allow the detection?

Simple answer - unknown except you have a real time list of all available proxies filtered by ones passing these variables and the ones that don't.

If you're really concerned - with Javascript, Flash, Java or ActiveX controls you can get the Browser sends it's real IP by executing some code at the clients comp.
Still - someone who wants to spam your board, hiding behind a proxy, maybe has these things disabled anyways.

Please could you give me the instructions
how to install hack class_core.php first edit and upload or upload hack hack and then edit class_core.php

Thanks for this,, really appreciate ur time taken,

[ikizbeyin]

Thanks a lot, installed...

[Stifmeister2]

I'm not sure if I understand it, this hack will convert proxy IP to "non-proxy" IP that the certain user has previously used?

What if someone has registered with a proxy and has always used a proxy?

[Paul M]

No, this only works on posts made after it was installed, and only if the proxy passes on the details.

[Stifmeister2]

No, this only works on posts made after it was installed, and only if the proxy passes on the details.
Well, better than nothing I guess. ;) I think I'll install this tomorrow.. Thanks. :)

[drupy]

Installed. Thank you!

Does it by any chance have any conflict with DNSBL -RBL/Open Proxy Monitoring/blocking mod below?
https://vborg.vbsupport.ru/showthread.php?t=201541

Like one makes the other not fully working as it should?

[Paul M]

Sorry, I have no idea.

[drupy]

Thanks a lot anyway.
I think I will ask the other modder the same question :p

[magiccen]

Lo instale y funciona bien, pero no surte efetco para los que navegan usando el ip hiden

[Paul M]

Sorry, this is an English only forum.

[MisterLaO]

i have done the edits and everything.. i have tested it in my forums but i cant see the small button i have uploaded to "/images/buttons folder"... how does this work?

i have tried using a proxy and posted on a test section. still i cant see the button.. i have uninstalled it ATM until i know whats wrong.

[MisterLaO]

uhhmmm.. any help with this one? :o

[Paul M]

What help exactly ?

[Rottimom]

The tool is nice - but in practice it is unfortunately rarely the case. The browser can be arbitrary IPs and agents concerned. Veracity = 0
If the user then over Tor or proxy's - why should these values at once credible?
Authentic is the public ip in the weblog - which can be used with the IP in the browser to compare - it only has the Board software can not access.

Uninstalled

[Paul M]

Um, huh ???

[sexgosex]

is that also can block the proxy user too or just find them?

[LeatherNeck]

Excellent work Paul, Thankyou.:D

[Hornstar]

Does vbulletin do anything like this? because I noticed it said " * Fetches an alternate IP address of the current visitor, attempting to detect proxies etc." If not, then why does vbulletin not do something like this if it is so beneficial?

[Paul M]

VB does have a bit of code to detect the original IP - but it does absolutely nothing with it.

[Hornstar]

This seems like such a useful mod, I can not seem to work out why vbulletin would not do this as default. Thanks for the great mod.

[Danny Diamond]

I am totally confused. I installed it and see absolutely no difference anywhere.

Where is this "Red Button" located? I look everywhere on known proxy users and I see nothing.

Please help.

It's installed on the board in my sig.

Thanks in advance.

[Paul M]

Read the notes on proxy detection.

Also remember this only applies to posts made after it is installed.

[The4um]

thank you!

it is not possible to know the members's real ip when a proxy is detected but in whos online list?

[Paul M]

If detected, the real ip will show anywhere in vb

[Zidane007nl]

I was looking at the online list of my forum and noticed that a registered member using a proxy has the IP 192.168.1.1. Is this a bug, since this is a private IP?

[Paul M]

No, its not a bug.

[Jaiibee]

Parse error: syntax error, unexpected T_VARIABLE, expecting T_FUNCTION in [forum path]/class_core.php on line 2285

Installed three times in two different text editors.
Any idea?

[Paul M]

Basically it means there is an error in the edit you have made, use a simple editor like notepad.

[Jaiibee]

Basically it means there is an error in the edit you have made, use a simple editor like notepad.

Im on mac.
I used ViM twice and TextEdit once.

If you get a chance, the attached class_core.php is what is currently active on my test board.

[Paul M]

Some of the edits appear to be in the wrong place (Steps 1 & 2) - and you also seem to have completely deleted the fetch_ip() function.

[Jaiibee]

Sigh, I missed the "Add below" part and deleted fetch_ip.
My bad, thanks for the support and modification, Paul M. Muchly appreciated.

[mtlcore]

How is this different than the IP function already in place by vbulletin?
example in the first step, where you say to add the code, there is another code which starts with:

Fetches an alternate IP address of the current visitor, attempting to detect proxies etc.

is this the same?

[chick]

Paul before I try this I was wondering if there is anyway to prevent mods from having access to this feature in their modCP. My mods cannot view IP's, only admins.... so I don't even want them to know this is installed.

I will await your reply before installing and thank you.

[Paul M]

This doesnt make any difference to the modcp.

[chick]

okay thank you. so I add this to the header template or headerinclude?

<!-- $Header: d:\cvs/3.8/Proxy-to-real-ip/Proxy-to-real-ip.txt,v 1.1 2008/10/04 19:57:57 pem Exp $ -->

clicks install (but will wait for answer)

Thanks again

[Paul M]

You dont do anything with that - just follow the instructions in the text file.

[Notorious Jay]

Thanks Paul works great!

[chick]

OK thank you... I noticed it at the top of the text instructions and thought it must be for something. Thanks Paul

[HolyKiller]

Installed ...

It works if user use transparent proxy

It doesn't work if user use Elite proxy


Better than nothing ... so, thanks :)

[dutchbb]

Mediawiki has a pretty big list of proxy ip's, idea to import those in this mod so more Ip's are detected as proxy?

[kyrenator]

thanks! i hope it will work!!!

[Paul M]

Mediawiki has a pretty big list of proxy ip's, idea to import those in this mod so more Ip's are detected as proxy?

Nope. The point of this is (was) to extract the real ip if a proxy is detected, having a list of proxy servers isnt going to help with that.

JFYI, I think I have mentioned this before, but this was specifically developed for my forum when the uk ISP Virgin Media (NTL as was) used to use transparent proxy servers. They no longer do this, so this is a bit redundant to me, but I have so far kept it updated. Whether I do that for vb4 I havent decided yet.

[korny]

Ok, lets say that the user has already been banned and his IP has been banned also. After I install this, the user decides to try to gain access to my board again through a proxy. What I am reading is that the proxy will be detected and the users real IP will surface. If thats the case, then he will not be able to see the board as his original (real) ip was shown and its banned already. Is that how this mod works?

[Byron]

How do you uninstall the hack?

What tables have been added?

Do we just uninstall the product?

[Paul M]

Do we just uninstall the product?
Do this, and revert class_core.php

[maplr4life]

nice :) installed.
thanks.

ps. You should mention that class core is in includes somewhere for the general vB noob

[MacHack]

Hello Paul, I was using this in the past, great product, worked great:up:. However after upgrading to 3.8.3, I went in to class_core and couldn't find the line in step 2 to add below now in class_core. And in further investigation they seemed to make several changes to the "detect proxies" section in class_core. Have they implemented these changes of yours and is this product is no longer needed if using 3.8.3? Thanks.

[kalisekj]

Sadly for the first time of installing a hack I have an irrepairable error. After installing this Hack My Who's online is no longer working, I get a DB error as seen below:
Database error in VBulletin 3.8.2 , It was working fine right before I installed this. I uninstall and revert back to my saved class_core.php file and who's online is still not working any more. Help! Please! I have Thread Thumbnail hack installed but this should not affect who's online.

Class_core has not changed in 3.8.3

[kalisekj]

I have had the server adjusted, and still i get the DB Error, more info though is that if I am a regular user pulling up online.php it comes up fine because it is not showing the ip addresses. So it has something to do with a db field not being added correctly or not being able to be found when an admin or mod attempts to pull up online.php. I am not to sure of what db field was added and where it was added, I did check my db on the server and do not see any proxy_ip field added to the db in any of the tables. I think that something is wrong here. Can you assist me in understanding what field needs to be added to what table. Thank You!

[kalisekj]

ok I have fixed the problem Now :D Thank You For this mod, Not sure if it works but time will tell.

[MacHack]

Class_core has not changed in 3.8.3

You're right Paul, my apologies! It was late and I couldn't find the line in step 2, found it today, haha. Thanks again for this and all your wonderful products!!

[James Birkett]

Hey Paul, last time I installed this modification it shown the IP icon as red even when the user wasn't behind a proxy. Was this a fault on my behalf, or has this been fixed at all?
Any information would be appreciated.

[Paul M]

That happens when you forget to do the file edits.

[Saviour]

Paul...

Thanks for this...installed with no issues. Instructions were straight forward and easy to follow. Running this on 3.8.3. I'll let you know how it goes.

Thanks for a great mod!

[Robbed]

It only displays the red icons when I disabled the ipinfo hack

Any suggestions?

[ricardoNJ]

Smetimes I see:
**********.board.xm.fj.dynamic.163data.com.cn

That is a user with a proxy IP? How can I ban' him , only copy and paste?

[Paul M]

This mod does not ban anything.

[ErrorLog]

Thanks Paul Installed

[Lolli]

Installed.

[SuperTaz]

I read the info of what it can do and tried 6 proxies and it still shows those proxies and not my IP. So, I guess I use some good proxies..

[Hornstar]

Did anything change in 3.8.4?
Because I re did the changes to class_core.php in 3.8.4 like I did with every other vb release but this time, every post appears to be from the same proxy.
The Proxy Server IP Address is: PROXYIP
did I do something wrong, or has something changed?

Edit: I spoke to soon, It appears everything is working now.

[Paul M]

You did something wrong. Nothing has changed in 3.8.4.

[unforsaken]

XML Error: Not well-formed (invalid token) at Line 3 on install

That means you have a corrupted xml file.

[DeanLag]

I have this mod installed on my boards annnnd someone using "anonymouse.org" (I think its a browser program that goes through a proxy or whatever?.. not sure" and it didn't detect his real IP. How do I know he's using a proxy? I IP traced him and yeah, showed me another IP.

[hpidriver]

I would looooooove this mod, but it does not work for me. I am suppposed to be editing class_core.php in the includes folder correct????? Please advise what i am doing wrong, i have installed and did everything in the directions and see no changes at all.

[Paul M]

What change exactly are you expecting to see, that you dont ?

Had this off one user.. interesting

[Log on]

I installed it,,, but how I can manage it OR how I can see the real IP ?

thank u

[Lean Bodies]

I messed something up.

When I did the edits and then uploaded the product, I lost my custom image header, colours reverted, some buttons like the who's online, etc show as text. Basically, something is jacked up.

I undid the edits and deleted the product but it hasn't reverted.

Any ideas?

[Paul M]

Not really. Its hard to see how this could affect any of those things.

[Asterix_ita]

thx Paul installed

[Kahuna900]

Installed, made the changes to class_core.php and now every ip post icon shows as the proxy icon and every ip is listed as; The Proxy Server IP Address is: PROXYIP.

[Paul M]

Either, you havent made the changes properly, or you havent uploaded them, or the changed code is not running - what you describe is what happens when the plugin is running but the class_core changes are not.

[Delazar]

Hello Paul,

does an update come for vB4?

[Tanapangarap]

Hi.

My forum is version 3.7.3. I use version 3.7.003 of your modification. Is there a significant difference between that version and 3.8.001? In other words, is it worth the update if you already have the former? Also, version 3.8.001 says it has a dependency of 3.8 minimum. I was wondering if this really means that the modification won't work or is likely to have problems with the version of vBulletin I am using, or if it just means no support for anything lower than vBulletin 3.8?

Regards,

Kevin

[Paul M]

There is no significant difference between the 3.7 & 3.8 versions.

[dacho]

I installed it on my system, I still receive the proxy IP and not the real IP user's

[TheInsaneManiac]

Problem... I have a style that uses PNGs. So now my IP image is not displaying because it's broken.

[Paul M]

Edit the postbit_proxyip template for your png image.

[jkcerda]

sweet.

[jkcerda]

is there a way to automatically ban them if a proxy is detected?

[Paul M]

No - and that would be a very bad thing to do.

[www.ch-joy.com]

thanx :-)

[jkcerda]

No - and that would be a very bad thing to do.

ok, anyway to hide the registration page if Proxy is detected? that would kill a huge percentage of trolls:D

[Paul M]

Trolls are unlikely to use a proxy server that is detectable.

[darknusens]

Thanks for the awesome work Paul! Installed*

[jkcerda]

I read the info of what it can do and tried 6 proxies and it still shows those proxies and not my IP. So, I guess I use some good proxies..
same issue here tried 4 proxys & posted using them, not flying :confused:

[jkcerda]

I just noticed, you have to check the POSt and not view "whos online", be just a bit careful, those with Iphones show up as Proxys.

good hack, thanks Paul:up:

[mesdar]

thank you

[korny]

If thats the case, then he will not be able to see the board as his original (real) ip was shown and its banned already. Is that how this mod works?

Paul, am I way off on what I said here? Is this what this mod does ^^^

[Paul M]

You are correct, however, its not a case of the proxy will be detected - but only if it is detected, and it passes on the original ip. Annonymouse proxy servers (quite obviously) do not do this.

[Amiga Harrison]

I was looking at the online list of my forum and noticed that a registered member using a proxy has the IP 192.168.1.1. Is this a bug, since this is a private IP?

I'm getting this with a few different members on one of my forums. What causes it to log a LAN IP as the real IP?

Also you mentioned somewhere that the mod does log the proxy IP to a hidden field, but then doesn't do anything with it. Where is this hidden field? If a member is logged on my forums with a LAN IP then I will need to check the proxy IP that was logged to do further checks.

[Paul M]

You view it by viewing the ip screen in the postbit.

[Hornstar]

Will this still work with 3.8.5 (Since I think there were changes to class_core.php) Just wanted to double check before I upgrade.

[Paul M]

The minor change to class core has no effect on this.

[Hornstar]

cool. Thanks Paul.

[Erica1977]

Nice Thanks.

[MentaL]

still cannot get this to work , keeps showing proxyip.. Product is imported and class_core edited, all it does it display the real ip and outputs proxy ip as "PROXYIP".

Anything i need to enable on my server?

[Paul M]

If you have done the edits correctly, and installed the product, it should work fine.

Bear in mind however that it wont fix old posts that say proxip, it will only work on new posts.

[ETDC]

Does this reveal both proxy address and real address on registration - or just when the user posts? :)

[Paul M]

If it detects a real address it will store it as the registration ip.

[ETDC]

Thanks Paul - so it doesn't store both?

[Paul M]

Nope. It only stores both for posts.

[madmax1228]

[xlguy]

Trying to install this on large forum with over 5m posts, product installation seems to be taking a long time as it does "Adding Column to Post Table" if this process fails due to timeout will it corrupt the database at all? Also if I want to remove the plugin will it remove the columns?

[Paul M]

If it timesout I think you should be able to just install it again. If the column exists it will just bypass adding it.

Dont use the uninstall option as that will attempt to remove the column, leaving you back at square one.

It wont corrupt anything, mysql will do what it was told to do, its just that php wont hang around forever waiting for it.

[xlguy]

Thanks, it did go through in the end - so my suggestion to anyone with a similar number of posts is to be patient and keep waiting :)

Thanks.

[Paul M]

Not really sure what response you want, but as I have no access to your site theres not really much i can tell you.

[dutchbb]

It's solved, not sure what happened. Thanks for your response.

[dutchbb]

I had to uninstall it because it didn't work at all and some members started to get different members IP addresses. We also have the mod that detects login of two accounts on the same IP, maybe there was some conflict there.

[Wreck713]

anyone know if their is a conflict with the above? As I also have that mod but would like to install this one as well.

[Marvin Hlavac]

Paul, this mod is EXACTLY what I needed! My site is behind a proxy now, and I needed to see IPs of visitors instead of the IP of my proxy. It works! It actually started to work the moment I uploaded the modified class_core.php file. Do I need to import the product, too? I don't need the red px.gif in my use case. Will I miss some other functionality if I don't import the product?

Again, thanks so very much for sharing your product with the community!

[Paul M]

The rest is basically to store both ip's for posts - but in your case thats not really necessary as the original ip will always be your proxy.

[Marvin Hlavac]

Many thanks, Paul!

[Dimoks]

Thank You!
But now some webmasters use flash technology for identify real ip adress
Sample http://super-socks.com and http://www.ip-score.com/ (run test)
Flash have very high percent identify real ip. Do you know such plugin ?

[forum4]

Thanks for this hack.:D

[ChiNa]

I am simply amazed by this one, I had so many users using proxy and this detected them all! Thank you Paul, I was always wondering who made this untill I registered vBulletin.org! Thanks for an amazing plugin!

by the way I have a question I head that putting this line on top of my Config file, it will also show the real ip of the users, is it true and what is it used for:
$_SERVER["REMOTE_ADDR"] = ( isset($_SERVER["HTTP_X_REAL_IP"]) ? $_SERVER["HTTP_X_REAL_IP"] : $_SERVER["REMOTE_ADDR"] );

Thank you very much

[Paul M]

Its slightly true - HTTP_X_REAL_IP is sometimes used, but isnt as common as some of the others.

[ChiNa]

Thanks for your reply Paul appreciated,,

[VIP Hawaii]

Thanks! It blocks various proxies, plus the ones it can't totally block (yet?) it does so far block from REGISTERING. Good work! :)

[laminedj]

Hello,

Is it working with vB 5.05?

[Paul M]

No, there is no vB5 version of this.

[Terrablade]

Ouch. It messed up my skin...
Cant have it on.. its messing up the templates :/

[Terrablade]

This seems not to be working on vb3 i see no red thingy when users log in with proxy. Tested it using a proxy on a test account.

[Paul M]

This works just fine on vB3, it was written for my vB3 site, and is still running 9 years later.

[Terrablade]

Any ideas what could be wrong then?
No red puter showing on users login in with proxy .

[millardjb]

I installed this add-on following Cloudflare support's recommendations to restore original ip addresses in vbulletin. It worked perfectly.

I only need it for this function.

Will the mod continue to work if I disable IP logging in the vBulletin options -> Message Posting and Editing Options?

[Terrablade]

seems not to detect ANY real ip at all.. Only says. Real ip: Proxyip. rofl

[Paul M]

Then you have an error in the set-up somewhere. :)

[Terrablade]

And I stand corrected :)
