Extension:MWBlocker

What this extension does
Tool to hook in with an obsolete proxy-blocker, used briefly by the Wikimedia Foundation circa 2005 until early 2006. IP addresses of editors would be sent to a daemon process which would queue up open-proxy checks, then write IP addresses of hits to a log file which could be loaded into $wgProxyList in your LocalSettings.php

The actual proxy checker tool code was written in Boo (Mono-based Python-like language) and is floating in SVN should anybody want to pick it up.

Installation
To install this extension, add the following to LocalSettings.php:

Configure the location of the daemon & debug settings if necessary:
