S4X8 ProxyKicker

What is this?

This is a plugin for Bukkit made to block connections from anonymous and public proxies like Tor exit nodes or SOCKS proxies at the Minecraft server Mine21.

Installation

To install the plugin on your Bukkit server, you may either download the pre-built version, or compile it yourself.

To compile it yourself, you need Oracle Java Development Kit v1.6 or newer, Maven 2, and Git. When you have all of them downloaded and installed, you have to grab the source code using GIT and compile it:

git clone http://github.com/socram8888/ProxyKicker
cd ProxyKicker
mvn clean package

Maven will automatically download all the dependencies. It may take more than five minutes if you have a slow internet connection, but usually it will take less than a minute.

The resulting compiled Java Archive file (.jar) ready to be used will be at /target. Just move it (or copy it) to Bukkit's plugin folder.

Configuration

The configuration for the plugin is stored in a YAML-formatted configuration file at /plugins/ProxyKicker/config.yml:

# ProxyKicker configuration file

# Expiration of proxy list cache, in milliseconds. By default, a week. Setting this value to zero or less will disable caching.
tor-update-interval: 604800000
# Unix time of last update. This value should not be modified manually. A value of zero or less forces an update
tor-update-date: -1

# Put on this list feeds for the Tor exit nodes.
tor-list:
- http://torstatus.blutmagie.de/ip_list_all.php/Tor_ip_list_ALL.csv

# Every time an user connects, ProxyKicker will scan for these ports on his/her endpoint, and will kick him/her if one of the port is open
proxy-ports:
- 3127
- 3128
- 1080
- 6666
- 6668
- 6667
- 6673
- 42321

This plugin will automatically download at startup a list Tor exit node database if tor.db does not exist or has expired.

You can skip checking for certain users by using PermissionsEx or another Bukkit Permission plugin and adding them the permission node "proxykicker.bypass".

About the author

My name is Marcos Vives Del Sol, aka "socram8888". I'm a 18-year-old Spanish guy who likes programming useless stuff that nobody uses. If you want to report a bug, ask for a new feature, or just say hello, you can contact me in my e-mail account socram8888@gmail.com.

This plugin is was based on a early version of proxykiller, programmed by jcarlosn (who also continued developing of the plugin - see ZeroProxy). This initially became as a fix for some race-condition bugs it had which made the server crash, and evolved into a full rewriting of the plugin. Right now, no line from the original code has been left.
