nginx_ipset_blacklist¶ ↑

An nginx module for using netfilter ipsets as a black/white list. In comparison to standard nginx access module this allows for dynamic list updating, without nginx reload/restart.

Installation¶ ↑

• Get youself a linux server with root access

• Install ipset 4.4 (see ipset.netfilter.org/install.html)

• Get nginx source code, unpack etc.

• Install libssl-dev, pcre and other nginx requirements

• Configure nginx with this module:

  ./configure --with-module=/path/to/nginx_ipset_blacklist

• Compile, install

• Configure nginx to run workers as root (this is needed to allow access to ipsets)

• Create yout ipset and add some 'offending' ips to it:

  sudo ipset -N myblacklist iphash
  sudo ipset -A myblacklist 127.0.0.1

• Start nginx

• Profit!

Usage¶ ↑

Sample nginx config:

user root;
worker_processes  1;

events {
  worker_connections  1024;
}

http {
  blacklist "myblacklist";
  include       mime.types;
  default_type  application/octet-stream;

  server {
    # your server configuration goes here
  }

  server {
    whitelist "my_whitelist"; # this server will not use global blacklist, but instad use local whitelist
    ...
  }
}

For blocked ips server will respond with 403 error to any request.
