Add-On Releases - DNSBL, RBL - Open Proxy monitoring/blocking

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):

PHP Code:

global $rblInstalled;

if ($rblInstalled) {
$remoteIsProxy = rbl_livecheck(1, $_SERVER['REMOTE_ADDR']);

//
// .. your code here ..
//

}

To be honest: I almost forgot that part. But I'm thinking of migrating my own forum to the new version, so - yes, definetively! Thanks for reminding me!

I think it's more about reversing the process or something like that. I haven't checked that mod more than reading the thread, and it feels a bit unwise to ban by iphistory since IP's tend to get old very fast. A cache or some kind of agechecking may be a solution for it.

I've just upgraded to 4.0 and currently learning the new system, so the solution is getting closer!

Any update status for vb 4.x? Would be very nice to use this addon on vb4.

As soon as I can, I would say. In all this chaos I suddenly sitting here with a newborn child also, so I'm trying to catch up with everything that I missing. I'll do my best, since I need it myself too


And a little FYI: Time to change the blitzed bitmask, perhaps?

The DNS Blacklist has also been updated:
