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):

Not sure if this can be answered but what kind of server load does this add if it's checking new registrations and posts?

I have a large board with alot of new posts. My 1st thought would be that it would impact the load significantly.

So.. I only wanted this script to be active at registration -- but still saw a dramatic reduction in performance on calls to global_start in all other locations.

I made the following adjustement;

Block Disabled:      (Update License Status)  
Suspended or Unlicensed Members Cannot View Code.

Added right after the global-line in function rbl_livecheck. There is really no need to be running all this code on all calls to global_start if the rblblockonregister switch is on.

No proxy is blocked at registration

axinos, I have just updated a few things in the dnsbl, so hopefully we may get more hits now!

FYI: Time to change the blitzed bitmask, perhaps?

The DNS Blacklist has also been updated:
  • Live reporting from scrapers
  • DNS runs on MySQL so everything reported goes live immediately
  • Daily statistics about added and removed hosts

Yes, it should! There are actually separately released versions for each version of vB!

You can find it at http://www.vbulletin.org/forum/showthread.php?t=201541
