If you're running a Rails server on Ubuntu, protecting your server is as simple as deploying your app with Moonshine, with the ssh, iptables, and denyhosts plugins. It requires maybe 7-10 lines of configuration to have a fairly well-insulated system: # config/moonshine.yml :ssh: :port: 9024 :allow_users: - rails # app/manifests/application_manifest.rb configure({ :denyhosts => { :admin_email => 'admin@example.com' } }) recipe :ssh recipe :iptables recipe :denyhosts
