- - Miscellaneous Hacks - Check Proxy RBL on New User Registration. (https://vborg.vbsupport.ru/showthread.php?t=131852)

Ok, I had to entirely uninstall this script. It said that it had a positive match on a user's IP address that attempted to register. WROOOOOOOOONG... the IP address resolves to a local ISP here in Detroit, MI. Crazy!

So?
Could that user be an open proxy or maybe one has been run before at that IP?
Did you goto Sh and look up the IP and seen what it said?

I went to ws.arin.net and it resolves to WideOpenWest's IP address range.

What's the IP?

Can the IP Black list block a range of IPs such as 120.45.*.*?

Good question, I was about to ask the same thing. Most of my registrations are inside Switzerland, and I was getting a couple of addresses inside dynamic ranges blocked by list.dsbl.org

Remeber the more IPs you add to the "blacklist" the longer it takes to process a registration... I'm not sure what list length will = a performance degredation.

Actually, since you are only doing a simple match here, I can't imagine that it will make TOO much off a difference. Remember this plugin in only firing on new user registrations, it's not as if it is firing on every single page. Therefore, probably not that much reason to stress :-)

Top marks on a excellent mod by the way!

Here's some unsupported and untested code that can be used to modify the current version of Proxy RBL mod (4.0) to work together with GLA (Geographic Location Awareness). This allows you to specify an additional whitelist or blacklist based on the country where the user has registered from. In my case I seem to have quite a few Swiss IP addresses listed, but most of my registrations are from Switzerland. Therefore I simply whitelist Switzerland. You can also use this so users from a certain country are always matched, regardless of whether their IP address is listed in a certain blacklist.

I haven't made a fancy user interface for this, because this is not my mod. My code is posted freely here for Daniel to consider implementing as standard. Please remember that unless you have installed and tested GLA first and it is working (details on the GLA thread), then this code won't work. Right let's get started:

Go into the AdminCP -> Plugins and Products -> Plugin Manager -> DMeNTED's RBL Checker -> Check IP against RBLs/IPs. Click the large edit box and locate this code:

Code:

      if ($DM_rblcheck_result == $DM_rblcheck_srvmask) {



            // ********************** NOTIFICATIONS **********************

Above this section insert:

Code:

// Modification to incorporate country checks into RBL checker. This will only work if GLA is already installed, tested and working

// Obtain GLA here: https://vborg.vbsupport.ru/showthread.php?t=151601

if (isset($vbulletin->session->vars['country']))

{

    // Country blacklist - enter a list of countries which are exempted from the RBL checker (use valid *lower case* ISO 2 letter codes only!)

    // See http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 for list of codes

    // example: $whitelist = array('gb', 'fr', 'it');

    $whitelist = array();

    if (in_array($vbulletin->session->vars['country_iso2'], $whitelist)) 

    {

        // We have a match on the whitelist, bail out of the entire plugin, but reset the variables first.

        $DM_rblcheck_result = null;

        return;

    }

    // Same as above example for whitelist. People from these countries will be flagged as positive matches, regardless of the RBL status.

    // Think carefully before using the blacklist - it is generally not recommended to ban entire countries 

    $blacklist = array();

    if (in_array($vbulletin->session->vars['country_iso2'], $blacklist)) 

    {

        // We have a match on the blacklist, set the variables and continue

        $DM_rblcheck_result = $DM_rblcheck_srvmask;

        $DM_rblcheck_errcode = "Matched a blacklisted country: " . $vbulletin->session->vars['country'];

    }

}

This modification is untested (though it is running on my system, but I haven't had any alerts yet so I can't say 100% whether it is working). If it works for you - maybe say so. Don't forget that you have to insert the correct country codes into the code (see the comments in the code itself), and don't get to use 'quotation' marks and commas to separate multiple entries.

Now to add the country name into your reports find this line:

Code:

$DM_rblcheck_errcode = "MATCHED IN THE RBL DATABASE of the " . $DM_rblcheck_rblserv . " RBL.";

And replace with:

Code:

$DM_rblcheck_errcode = "USER FROM: $vbulletin->session->vars['country'] MATCHED IN THE RBL DATABASE of the " . $DM_rblcheck_rblserv . " RBL.";

Also, further to this post, I recommend moving the hook used for Check IP against RBLs/IPs to register_addmember_complete (and change to execution order 4 if you do this), due to the fact that multiple notifications get sent for every bot that turns up.

It might be useful to duplicate sections of code in both plugins so that blocking is done in the Check IP against RBLs/IPs plugin and notifications are done in Auto-Ban or Flag for Moderation plugin. This would avoid all the unnecessary notifications for bots that never succeed in registering anyway.

Remember, just to repeat myself again (I know some people have trouble reading instructions sometimes). Do not ask for support for GLA on this thread - install it and if it doesn't work go through every post on the GLA thread as there are steps for verifying it on that thread.

What is happening is when it hits process, and say the user puts in the wrong captcha, doesn't match their passwords, doesn't put in a required field, etc. When you use the _complete hook it fires once the user has properly filled out the registration form. Only use this hook however if you want the registration to complete, but not get multiple notifications. If you are blocking registrations, then leave it using the process hook.

Has anyone confirmed that this works? I use the NoSpam! mod, and because of that, I get bots trying to register 6 times with their accounts banned (which is good). However, if this mod allowed NoSpam! to run first, they wouldn't even get to the point of registering an account most of the time. I believe I tried the above several months ago and it didn't work. Any suggestions at getting this to run after NoSpam! verification/etc?

Thanks

Hey everyone - I apologize for the extended absence. I am back and plan on redesigning the hack with even more features.

Right now the list includes:

- Ability for blocked registrations to send a message to admins in case they feel there is an error.
- Ability for admins to whitelist IPs from the automatic posts/PMs.
- Ability to blacklist or whitelist using a mask - #.*.*.*
- Ability to ban + blacklist IP from any post for spammers that sneak through.

I'm also toying with the idea of keeping a central RBL that the RBL checker reports to on positive or manual hits...
