Not Supported DB Changes Uses Plugins  

History

I've had some problems with abuse via open proxies for a time ago, and when we were banning abusers, they always found a new proxy to use and register new accounts with. Since this forum was a large type we could'nt just ban e-mails etc just like that, because this was leading to a very large amount of other banned users too.

At IRC, in the other hand, we had Open Proxy Monitors, that was banning everything that was blacklisted in some DNSBL-databases. No spammers had a chance to get in there as long they were listed in such database.

This is a plugin that blocks blacklisted hosts from some different DNSBL's. It uses the global_start-hook, a very simple handler for blocking proxies, and a vBphrase called OPM_Deny.


April 2006

The source has been rewritten a bit. The proxychecker is now using a cache that, by default, stores all ip's in a database for 6 hours. It scans some DNSBL's and can be configured to block proxies from bitmasks (defined in the plugin) which makes it a little bit more reliable, because it does'nt block everything it see).

Configuration is made from the plugin (hopefully there will be a nice admin interface in the future). Exceptions (ip's that can pass through this system even if it is a proxy) are also handled differently now.

How does it work with other vBulletins?

This filter actually works with both 3.5 and 3.6, but for now, they will be separate versions, but for 3.5 and 3.6 you should look here and for 3.7 you should look here.


How to use the compatibility thing

If you have a plugin that you want to use together with the proxy monitor (only returns a value if a an ip-address is registered as a proxy or not) you can call the function rbl_livecheck like this (example):

Very nice mod, thanks. I'm in progress to implement a bit more commlicated task, but in similar way. Could you share some statistics from you board?

1. How many %% of disturbers were blocked immideately?

2. How many wrong blocks?

3. How many ACTIVE distubbers still exists (if they uses payed proxy lists and so on)?

Does this block users from registering or will it also block them from posting (if they're already registered) ?

With the default settings, there has been probably 2-3 wrong blocks in 6 months. Most of the incoming (external) reports also says that temporary Tor-nodes causing the problems.

Both - there's a specific setting for "Only block on registrations".

How does this plug-in compare to the old "Check Proxy RBL on New User Registration." plugin below (that still works with 373)?

is there a way to allow only admin login, if your at an open proxy ?

for 3 days now since i used this, its not blocked me, however for some reason, its saying i am blocked

thi is the message

You have been denied access to this forum. The reason is that you are visiting us from a place that has been blacklisted as an Open Proxy. You have to fix this, and return.

If you want to know exactly where you are blacklisted, go see www.tornevall.net/cgi-bin/ip.cgi

I haven't tested that version yet, but I think it should do the same as this.

You should be able to reach admincp and add yourself to a whitelist.

But why not? I'll look into some kind of "override protection on fly"-function too for the next version..

Registration-checks only blocks registrations. The other option is site-blocking.

If you are getting "MySQL Server has gone away", the forum won't be running, assuming they are talking to the same database server (MySQL).

You will get an error for every "hit"/request/visit on the forum.

Check your system / processes.
