Prevent guests/users from using proxies at your forum

[borbole]

This hack will allow you to prevent guests/users from using proxies at your forum. You can dissallow proxies for the forum as a whole or to prevent only registrations with proxies. You can enable and disable it at the Acp of your forum where you can control the settings for the mod.

Note: As you know there is no such way of preventing proxies 100% but it helps a lot. I tested it with a dozen proxies and it stopped 8 of them.

Thank you, I'll add it right now! Great mod!

[borbole]

You are welcome. Glad it came in handy.

[John1uk]

just what i needed ... :D thankyou

[Rickpwns]

You Rule,
I needed this!

An option to change the 'Not Allowed' Template would be nice :)

[simmer1974]

Great mod!

[borbole]

Thanks for all your feedbacks/comments guys. Appreciate them :)

@Rickpwns, atm I don''t have much free time to edit the mod, maybe later on. In meanwhile you can change the error text at the xml file.

Pretty useless mod, as it will only detect low privacy proxies that forward client information - people that use proxies for anonymity measures which provide a standard level of security wont be detected by this. Try it out for yourself.

There are like millions of proxies out there. There is no way to detect all of them.

Exactly.
This mod is useless, as it wont detect any actual proxies but just block registration access for everyone using a low-anonymity-proxy sometimes necessary for working within special networks or given to you by some providers.

Then don''t use it. Instead of repeating yourself like a broken record, either find another mod, or create your own. What can I say.

I just wanted to point out that its pretty useless and annoying to have this mod installed since it will only bug legit users and not those using anonym proxies.
Didnt mean to offend you, but... thats just the way it is. Besides, a fsockopen on every page load seems like a really, REALLY bad idea... I mean REALLY bad. And basically youre blocking everyone with port 80 forwarded, which seems like an idea far worse...

Technically there is no real possibility to find out wether a user is using an anonym proxy or not. You'll have to rely on your mods if you have troublemakers coming again and again...

[BlackHoster]

Great thank you ...works even with VB4
INSTALLED

[kevinkun]

umm, I was in china a few weeks ago...
& I was trying to access my forums through the internet access I had there...

but the modification prevented me.. because apparently I was using a proxy...

what should I do?

[D_light]

I love this plugin, and I made it even a bit more fun for people who think that proxing through other servers is smart:

Edit this code:

<phpcode><![CDATA[if ($vbulletin->options['no_proxy_enable'])
{
if( @fsockopen( $_SERVER['REMOTE_ADDR'], 80, $errstr, $errno, 1 ) || @fsockopen( $_SERVER['REMOTE_ADDR'], 443, $errstr, $errno, 1 ))
{
standard_error(fetch_error('no_proxy_message'));
}
}]]></phpcode>
</plugin>
<plugin active="1" executionorder="5">
<title><![CDATA[No Proxy Allowed.]]></title>
<hookname>global_start</hookname>
<phpcode><![CDATA[if ($vbulletin->options['no_proxy_allowed_enable'])
{
if( @fsockopen( $_SERVER['REMOTE_ADDR'], 80, $errstr, $errno, 1 ) || @fsockopen( $_SERVER['REMOTE_ADDR'], 443, $errstr, $errno, 1 ))
{
standard_error(fetch_error('no_proxy_allowed_messa ge'));
}
}]]></phpcode>


And where it says:

{
standard_error(fetch_error('no_proxy_message'));
}

and

{
standard_error(fetch_error('no_proxy_allowed_messa ge'));
}


Replace it with this to forward to any site, page or w/e you want:

header( 'Location: http://www.yourwebsitehere.com' ) ;


Hope the author doesn't mind me posting this, had some fun with adding this to our use of the plugin. Which I will add is a GREAT blocking for any and all proxy servers, thank you very much for making this!

[mp3president]

Sorry, dislike this mod because a lot of problems without using proxy.
I'll keep on working this problem manualy.

[Max Taxable]

Got it, installed it, and it works.

3.8.6

Thanks!

[DaBoss2000]

can this be updated to blocc users without a User-Agent(ie, browser)? this will greatly help me out if this can be done and will stop a dos attacc on my site quite easily

[dutchbb]

Finally one that works, I tried every one of them here and they all failed except for this one. Good work.

[dutchbb]

I shouldn't have said anything... it doesn't work with http://www.anoniem-surfen.nl/ for example. :(

[Scyther]

Thanks...marked installed.

[geocodes]

This blocked some of my users who didn't use proxies and were connecting directly to the site with their ISP (Comcast for example). It would be nice if the creator could modify the code to address this bug.

[ChiNa]

This one is not working right, this is also making normal users with normal IP get blocked,, How come,,

[biftek]

because as mention of page one , there is many legit reasons why someone might be behind a proxy

[VIP Hawaii]

Hey, this REALLY WORKS!! .. thanks!

[Gostemilov]

Great mod! Installed!
