Proxy ip to real ip conversion

This modification is no longer available or supported.

A simple modification I did for our forum that was originally based on the Proxy Detector Hack (v3.0). Obviously, like all proxy server detection hacks, this will only work if the proxy server passes the appropiate http variables.

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

i.e.

* The real ip/host is displayed in who's online

* The real and proxy server ip's are accesible for each post, the button is red for members using a proxy.

* The real ip is searchable in the admin/mod cp, not the proxy ip.

* The real ip is bannable by admins (no moving to another proxy to avoid a ban).

etc etc.

The installation should take about 10-15 mins (4 file edits, 2 phrase changes, 1 new template, 1 sql query, 1 new image).

I'm regarding this is quite a serious error as IP information needs to be correct.

Please help!

Hi Spinball,

This problem is corrected in v1.1 - which has a better ip extraction and check.

The steps to update are in the new zip file.

Thanks. I'll keep an eye on it. For the bad IP addresses, I'll just edit out anything after the first 4 numbers and in the case of them having 'unknown' in the text I'll leave them blank. Do you agree with this course of action?
FYI I have installed this hack and the IP Info hack so my moderators can track down the morons causing trouble with duplicate registrations and proxys.

I installed Proxy Detector 3.0 to my VB 3.01 - and next to the IP button is _HacNho - it doesnt seem to be working, any idea what might cause this? thanks>!

Yes, if you really need to edit old records that are in error then that would work. I'm not sure it is worth the effort, depends on how many you have I suppose.

Well I didn't write that hack, but by the sound of it you have a small error in the postbit_ip template. Make sure you have copyied that part correctly.

Hmm, Well you are right, the postbit_ip template code in that proxy detector text file is a bit duff. I just took that hack, as was, and added it to my zip file assuming it was ok.

You could replace it with this which should work ok ;

PHP Code:

<if condition="$show['ip']">
    $vbphrase[ip]: $post[ip] 
    <if condition="($post[proxyip] != '')">
        <br>Proxy Detected - Real IP: $post[proxyip])
    </if>
<else />
    <if condition="($post[proxyip] != '')">
        <a href="postings.php?$session[sessionurl]do=getip&amp;p=$post[postid]"><img class="inlineimg" src="$stylevar[imgdir_button]/ip.gif" alt="$vbphrase[ip]" title="Proxy Server : $post[ip] - Real IP: $post[proxyip]" border="0" /></a>
    <else />
        <a href="postings.php?$session[sessionurl]do=getip&amp;p=$post[postid]"><img class="inlineimg" src="$stylevar[imgdir_button]/ip.gif" alt="$vbphrase[ip]" title="$post[ip]" border="0" /></a>
    </if>
</if> 


But it's a bit academic if you are applying my Hack, as part of mine replaces the postbit_ip template code again anyway.

Paul.

Sorry, but you will have to be a little more specific.

What steps have you done, and what is the problem ?

Hello,
I have some members that I know for certain are behind a proxy. however, this hack hasn't changed or added the second "red" comp in their posts.
I do believe that it is showing the correct IP, but now I can't see who else is behind a proxy.
If there is a proxy detected, will it tell me that a proxy was detected? I click the normal comp and it tells me the IP and the host, but not if they were behind a proxy.
On "who's online", nothing has changed either. All I see are the usernames,where they are currently on the site, and their IP address. Should i also see the host?

Depends on if they are using a completly anonymous proxy, or just a regular proxy
