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.

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.

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

We’re now ready to install the Moonshot software and its required dependencies.

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

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:

RadSec

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

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.:

Channel Bindings

Turn on channel bindings in freeradius by symlinking the chbind module: 

Testing

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.

Testing using the Temporary Identity Client (TIDC)

1. In window 2, (as the freerad user) run the tidc command:

   bash

   This uses the "tidc" binary which is used in the following way - tidc [hostname-of-trust-router] [rp-realm] [hostname-of-apc-server] [apc-name]

2. If the Trust Router connection was successful, you should see something like the following:

   In window 2 - TIDC output

Starting the Temporary Identity Server (TIDS)

1. In window 3 (window 1 should still be still running the FreeRADIUS server and window 2 the TIDC 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.

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.
