Bastion Cookbook

A Chef cookbook for configuring a server to be used as a bastion host for
remote access to and administration of an otherwise walled-off network.

Requirements

This cookbook is written to hopefully work on, or be expandable to, other
distros, but is currently only tested against Ubuntu Linux.

Some of the dependencies are pinned to older versions in order to maintain
compatibility--for now--with Chef 11.

Usage

Override any included attributes as needed and add bastion to your run_list.

Recipes

default

Refreshes the APT cache and configures the firewall and remote desktop (below).

firewall

If the firewall enabled attribute is set to true (the default), enables the
system firewall and pokes holes in it for SSH (port 22) from an
attribute-specified set of trusted networks.

If the firewall is not set to enabled, it disables it.

remote_desktop

Installs X2go, Google Chrome, and Firefox.

Attributes

default

default['bastion']['firewall']['enabled'] = true

Whether or not the system firewall should be enabled. This can be overridden to
false if, for example, port access is instead being handled solely in your
cloud provider's security configuration.

default['bastion']['firewall']['trusted_networks'] = %w(
  10.0.0.0/8
  172.16.0.0/12
  192.168.0.0/16
)

The set of CIDR ranges to allow access from in the system firewall.
