Moonshine_Iptables

A plugin for Moonshine

This plugin installs and configues iptables for your server. Just include the plugin and recipe, deploy, and you’ll have a nice secure system. By default, the firewall will:

  - Allow inbound ESTABLISHED and RELATED traffic
  - Allow inbound icmp, smtp, ssh, http, https
  - Allow inbound connections to unprivileged ports in the 8000-10000 range
  - Allow outbound connections to anywhere
  - Block everything else

Instructions

• script/plugin install git://github.com/railsmachine/moonshine_iptables.git
• To customize rules, use the configure method, passing the entire ruleset.

    configure(:iptables => { :rules => [
      '-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT',
      '-A INPUT -p icmp -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 53 -j ACCEPT',  # <-- Custom: Allowing DNS
      '-A INPUT -p tcp -m tcp --dport 25 -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 22 -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 443 -j ACCEPT',
      '-A INPUT -s 127.0.0.1 -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 8000:10000 -j ACCEPT',
      '-A INPUT -p udp -m udp --dport 8000:10000 -j ACCEPT'
    ]})
  

• Include the plugin and recipe in your Moonshine manifest.

    plugin :iptables
    recipe :iptables
