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).

Clicks install.

So, if I ban the proxy IP, "what happen?!"

If it's detected as a proxy then nothing. If it isn't detected as one, then it will get banned.

Will it work @ 3.5?

[Paul M]

I have a 3.5 version of this, which will be released in the last week of August (after my holiday).

In includes/functions_newpost.php

i didn't see:

PHP Code:

$DB_site->query("
            INSERT INTO " . TABLE_PREFIX . "post
                (threadid, parentid, title, username, userid, dateline, pagetext, allowsmilie,
                 showsignature, ipaddress, iconid, visible, attach)
            VALUES
                ($threadinfo[threadid], $parentid, '" . addslashes($post['title']) . "',
                 '" . addslashes($post['postusername']) . "', $bbuserinfo[userid], " . TIMENOW . ",
                 '" . addslashes($post['message']) . "', $post[enablesmilies], $post[signature],
                 '" . addslashes($post['ipaddress']) . "', $post[iconid], $post[visible], $totalattachments)
        "); 


i run vb 308 :ermm:


also; If I installed the early version, what should I modify to upgrade it to the newest version? Knowing that I delete the early hack file from my pc so I can't look for the difference between both.

Well it seems to be there for me, about line 423 (under "// ### POST NEW POST ###")

The early version of what ?

The instructions say " "This hack makes the forum always use the members real ip when a proxy is detected,"" and then "Obviously, like all proxy server detection hacks, this will only work if the proxy server passes the appropiate http variables." So, the claims following it are a bit confusing. They are written as it if always works. But they are a bit "optimistic" as they only work if the conditions in the first paragraph are met.

I am wondering just how many people work with a "non-anonymous" proxy?

[Paul M]

It seems perfectly clear to me - when a proxy is detected, the real ip is used, not the proxy ip. A proxy can only be detected if it passes the correct http variables. Only you seem to be confused.

1.5 million ntl customers in the uk for starters, as well as many companies and other ISP's.

I was not putting your hack down, so there is no need to be nasty about it. The reason I asked is because it seemed to be a contradiction, which confused me, and I wanted to understand how this great hack worked. When I install a modification on a board I like to try to understand how it works, rather than letting the "magic" of vb do the work. Thanks again for sharing your work.

There was no intention to be nasty, I'm sorry if you took it that way - I simply answered your questions.
