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 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?

See https://vborg.vbsupport.ru/showpost....85&postcount=9 for the first bit.

For who's online, it is an option (in Admin CP) to turn on host display, but this still relies on there actually being a reverse dns lookup record for the ip (which is nothing to do with me )

Thanks Paul. Yesterday I installed Proxy Detector v3.1 - for Posts and WOL which also allows you to see the Proxy IP address and Real IP address in Who's Online when User Agent info is displayed.

I think I discovered a bug afterwards in relation to the Revert function which caused my Whosonline template to disappear. I explained what happened in this post.

Today I added your Proxy IP Hack Modification v1.1. Can you explain why you've changed the text in the phrase thread_displayproxyip from

Below is text from original Proxy Detector v3.0 hack which is replaced

The proxy IP Address is: $postinfo[ipaddress]<br>
The proxy host name is: $postinfo[hostaddress]<br>
The real IP Address is: $postinfo[proxyip]
--------------------------------------------------------
to

Real IP Address : $postinfo[ipaddress]<br>
$postinfo[hostaddress]<br>
Proxy Server IP Address : $postinfo[proxyip]<br>
$postinfo[proxyhost]
-----------------------------------------------------------
Why was this necessary?

Also, in your postbit_ip modification one of the lines you add is:

<if condition="($post[proxyip] != '' & $permissions['adminpermissions'])">

I changed it to <if condition="($post[proxyip] != '')">

to allow my supermods to see the red gif identifying the proxy users.

Well I would have hoped it was obvious from looking at it. The old template has the ip's reversed (i.e. it displays the proxyip as the real ip, and vice versa) - there is also now a forth line to display the proxy servers host name.

Fine, it was just an extra check and should probably be removed anyway as it's a bit redundant. Interestingly, our supermods can see them anyway. If I do another update I'll probably remove it myself.

It was obvious to me, Paul but I wanted confirmation from a coder. Are you saying that original text display is incorrect? Why then hasn't someone informed mtha?

No, the original text display is correct for the way his hack works.

The main reason I wrote this [for our forum] was because when his hack detects a proxy, it still treats the proxy server ip as the real ip, and just records the real ip in the proxyip field. As detailed in post one of this thread, my hack corrects this 'problem' and makes sure the forum always uses the members real ip, even when a proxy is detected.

Thanks again, Paul. Just wanted further clarification as the fields appear to be swapped between your version and the original but your modification works and adds further benefits to the original without diminishing the original so thankyou for sharing it.

Paul, I need further clarification, please. With your hack installed and a member logs in using a proxy will that proxy address be stored in the database and be available to search in admin or mod cp to see which members use the same proxy server?

Or are proxy IP addresses ignored and not stored? Thereby, making it impossible to search and find proxy IPs shared by members.

Yes, and No. Both addresses are stored, but the ACP / MCP functions only scan the real ip data field, not the proxy ip field.

No, and Yes !. As above, the proxy server addresses are stored, but the current vB ip functions do not access them.

Paul, since installing your hack I'm getting weird results when searching in admin cp Search IP Addresses.

For example: a member called Scott-Wozniak has 640 posts recorded with 80.3.32.4 When I do a search "Find IP Addresses for user" and type Scott-Wozniak I get 80.3.32.4 However, when I use "Find Users by IP Address" and type 80.3.32.4 I get No Matches Found. What is going on here, Paul. Have others experienced the same problem since installing this hack.

I've checked other members including myself and some IP numbers listed when using Find IP Addresses for user return "No Matches Found" when entered as the search string in Find Users by IP Address to get the members name. But some IP numbers do return the member's name. Any explanation for this?
