System Preparation

Install Debian 7

The first thing that is required is a Debian 7 machine - this can be physical or virtual.

  1. Install Debian 7 (Wheezy) via usual mechanism (e.g netboot CD, ISO in VMware/VirtualBox or the DVD image.
  2. Choose the following server install options: "Debian desktop, SSH server, Standard system utilities”.
  3. Create/choose a secure root password and an initial system user account.
  4. Once installed, make sure you run an apt-get update and apt-get upgrade to ensure your system is fully up to date.
Tip

We would recommend using LVM when disk partitioning to allow easier partition/disk expansion on a live system.

Warning

After install, you will want to secure/lockdown the server as best practice dictates - for both the server and any extra software installed. This is beyond the remit of this guide but there are many guides available, e.g. for securing Debian, and SSH servers.

Configure Debian 7

Next, there are a few Debian configuration options that need to be set in advance.

Networking configuration

For production deployments, it is recommended that the Moonshot APC be assigned a static IP address.

For Debian networking information please refer to the Debian documentation: https://wiki.debian.org/NetworkConfiguration

Firewall configuration

The following ports are required to be accessible from the outside world, both in local firewall and in any external firewalls:

  • 2083/tcp (for RadSec connections to other Moonshot entities)
  • 12309/tcp (for Trust Router client connections - if using the Trust Router to broker trust relationships between entities)

Add the Moonshot Repository

  1. Add the Moonshot Debian Wheezy repository to your system. To do this, run the following command (as root, or using sudo):

    bash
  2. Install the Moonshot GPG key:

    bash
  3. Update the apt cache with the new repository information:

    bash

     

     

Install the Software

We’re now ready to install the Moonshot software and its required dependencies. Install the software by running the following command:

bash

If you try to start FreeRADIUS at this point, it will not currently start successfully as the certificates it requires have not been generated - they are created in step 3.1 below.

 

Configure the Moonshot APC

Next, we need to configure the Moonshot APC.

Configure FreeRADIUS

Certificates

We need to get FreeRADIUS to create some private and public keys to use for its RadSec connections. Create and install the certificates by doing the following (as root).

  1. Change into the /etc/freeradius/certs directory

    bash
  2. Edit the certificate generation properties in client.cnf, server.cnf, and ca.cnf as following:
    1. In the ca.cnf file:
      1. In the [ req ] section, add encrypt_key = no
      2. In the [CA_default] section, change the default_days from 60 to a higher number (this is how long the certificates you create will be valid for). When the certificates expire, you will have to recreate them.

      3. in the [ certificate_authority ] section, change all of the parameters to match those of your organisation. e.g.

        true
    2. In the server.cnf file:

      1. In the [ req ] section, add encrypt_key = no
      2. In the [CA_default] section, change the default_days from 60 to a higher number (this is how long the certificates you create will be valid for). When the certificates expire, you will have to recreate them.
      3. in the [ server ] section, change all of the parameters to match those of your organisation. e.g.

        true
    3. In the client.cnf file:

      1. In the [ req ] section, add encrypt_key = no
      2. In the [CA_default] section, change the default_days from 60 to a higher number (this is how long the certificates you create will be valid for). When the certificates expire, you will have to recreate them.
      3. in the [ client ] section, change all of the parameters to match those of your organisation. e.g.

        trueAll of the organisation parameters (countryName, localityName, etc) need to match in the three .cnf files but the commonName must be unique in each file)
  3. Clear out any old certificates in the directory

    bash
  4. Run the bootstrap script to generate the certificates

    bash
  5. Create a file that is the concatenation of the certificate and private key of the client.

    1. Create the file

      bash
    2. Cerify that the client.pem file starts with "-----BEGIN CERTIFICATE-----".

Moonshot UI credential store

We need to enable the freeradius user to use the Moonshot UI flatstore:

bash

RadSec

Next we need to configure RadSec. We do this by creating a file at /etc/radsec.conf with the following:

true

Realm

We next need to configure your realm in the FreeRADIUS server so that it knows not to send any requests for your own users off to another server.

  1. Configure your realm in /etc/freeradius/proxy.conf
    1. Open the file for editing and fine the line “realm example.com {“
    2. Above this, add the following, where YOUR_REALM should be substituted for the realm you intend to use for your APC:

      true

EAP Type

  1. Set the EAP type in use by moonshot (EAP-TTLS) by editing /etc/freeradius/mods-enabled/eap. Find the first instance of default_eap_type = md5 and change it to TTLS, i.e.:

Other EAP types should be supported (PEAP and MD5 have been tested).

 

Resource Provider Authentication

note

This information is implementation-specific and will be discussed separately.

 

Configure the Trust Router connection

The APC is fundamental to a Trust Router network, so the next step involves configuring the Trust Router client software and configuring its connection to a Trust Router.

Set up the FreeRADIUS and Trust Router users

We need to place the FreeRADIUS user and the Trust Router users into each other's groups to allow them to read each other's shared files.

bash

Configure TIDS

The APC also runs the Temporary ID Server (TIDS).

  1. Open the /etc/default/trust_router file for editing. If necessary, create it.

 

true

 

 

 

Testing

 

Now that we have the Moonshot IdP installed and configured, we're now ready to test! 

Tip

At this point you probably want three consoles open on the server, so that you can manually run various components separately.

 

Testing FreeRADIUS locally

 

The first test is to check whether FreeRADIUS is working in its most basic manner. 

  1. In window 1, run (as root user)

    bash
  2. In window 2, run (as root user)

    bash

    This uses the "radtest" utility which is used in the following way - radtest username password servername port shared-secret

  3. If this is working correctly you should see something like the following:

    In window 1 - FreeRADIUS server outputIn window 2 - radtest client output

Testing the Trust Router connection

To test the connection to Trust Router, we need to make sure the Temporary Identity Server (TIDS) software is running, then use the Temporary Identity Client (TIDC) software to simulate a connection to the Trust Router.

Starting the Temporary Identity Server (TIDS)

  1. In window 3 (window 1 should still be still running the FreeRADIUS server and window 2 the radtest command), run the TIDS software:

    bash

    trustrouter@apc.moonshot.ja.net is the identity that the trust router will use when provisioning keys - this makes it easy to spot in your own log files.
    Specifying your server's IP and hostname may seem redundant (and for single server deployments, it is!). You'll need to set the hostname and IP arguments a little differently if you want to enable some more advanced configurations (such as load balancing and key sharing).

    This uses the "tids" binary which is used in the following way - tids [your-ip-address] trustrouter-gss-name] [your-hostname] [path-to-key-database]

    When using Network Address Translation (NAT) or a firewall, you must specify your external IP address.

Run a test

 

Next Steps

At this point, you now have a Moonshot APC that is working. Now for the next steps:

Automatically start the software

FreeRADIUS

To automatically start FreeRADIUS, issue the following command (as root):

TIDS

We currently don't have an initscript for the TIDS, you have to run it manually.

Configure a real source of Authentication

Your FreeRADIUS server can currently only authenticate a single user - "testuser". At this point, you will want to connect to your management database. The FreeRADIUS site has information and instructions for how to do this.
