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 ..
//

} 
Report bugs if you find them...



Don't forget to install it

Is there still a huge problem with false positives? Right now, I'm limiting the DNSBL to opm.tornevall.org, because it blocks Tor and many anonymizers.

EDIT: How does it affect the server load? I temporarily disabled it, because when it was activated my load average rose by quite a bit. Maybe it was a coincidence.

Has anyone heard about relakks, the anonymous VPN (some swedish piracy sites has been writing about this, because it makes filesharing more secure)? I've been thinking a while on how this network opens for new abuse-methods into forums, so I decided (yesterday) to add a bunch of completely new entries (65025 ips) into tornevall.org's RBL-database as a preparation for the future. I haven't been testing this with this product yet, but I think adding relakks.tornevall.org into the RBL-list might work, if you'd like to block the Relakks network. I've added this system on another subdomain so this shouldn't interfere with opm.tornevall.org.

Can you check if ip-field in the the proxycache is set as a key? If not, this might cause problems wipe dupe keys. An alternative can be to optimize/repair the table.

I've also noticed that the proxydb can't handle ipv6 properly. Maybe thats something to look at.

This may sound dumb, but how do you check using tornevall.net? I can't see anywhere to put in an IP address.

I never added a field for doing that because of the risk of spam (like bruteforcetesting networks), but http://www.tornevall.net/cgi-bin/ip.cgi?q=<ip> should work.
