This project contains puppet modules for different pieces of software, in particular it is intended to provide the required installation steps for Internet2 implementations of Shibboleth IdP. The module has been developed and tested on Debian (Squeeze and Wheezy) and on Ubuntu (12.04 LTS) Linux systems.

The modules developed can be installed on a Puppet Agent running Puppet <= 3.8.7

The steps to have a Puppet Master installed correctly are:

• Install Ubuntu 12.04 LTS on the target machine, from the installation parameters, choose ONLY standard system utilities and ssh server to minimize the number of packages to be installed on the targed machine.

• Configure the network and the name resolution so that the machine reachable with its FQDN (as returned by hostname -f) from the Puppet Agents.

• Install last version of puppet by executing:

  • On Debian Squeeze:

    • wget http://apt.puppetlabs.com/puppetlabs-release-squeeze.deb
    • dpkg -i puppetlabs-release-squeeze.deb
    • apt-get update
    • apt-get install puppetmaster ruby
    • apt-get dist-upgrade

  • On Debian Wheezy:

    • wget http://apt.puppetlabs.com/puppetlabs-release-wheezy.deb
    • dpkg -i puppetlabs-release-wheezy.deb
    • apt-get update
    • apt-get install puppetmaster ruby
    • apt-get dist-upgrade

  • On Ubuntu 12.04 LTS:

    • wget http://apt.puppetlabs.com/puppetlabs-release-precise.deb
    • dpkg -i puppetlabs-release-precise.deb
    • apt-get update
    • apt-get install puppetmaster ruby
    • apt-get dist-upgrade

• Change /etc/puppet/puppet.conf by adding the following lines after [master]:

  [master]
  dns_alt_names = <your_puppet_master_hostname>
  manifest = $confdir/manifests/site.pp
  modulepath = $confdir/modules
  reports = store,tagmail
  
  

• Download from Github into you prefer directory the Puppet-GARRShibbolethIdP code and update submodules. In this README we download it into a new directory under /opt:

  cd /opt
  git clone https://github.com/ConsortiumGARR/Puppet-GARRShibbolethIdP
  cd Puppet-GARRShibbolethIdP
  git submodule init
  git submodule update
  
  cd Puppet-GARRShibbolethIdP/garr-common
  git submodule init
  git submodule update
  

• Move or Link all modules from the proper folders of this GitHub project to /etc/puppet/modules:

  cd /etc/puppet/modules
  for i in /opt/Puppet-GARRShibbolethIdP/puppetlabs/*; do ln -s $i; done
  for i in /opt/Puppet-GARRShibbolethIdP/garr-common/garr/*; do ln -s $i; done
  for i in /opt/Puppet-GARRShibbolethIdP/garr/*; do ln -s $i; done
  for i in /opt/Puppet-GARRShibbolethIdP/garr-common/puppetlabs/*; do ln -s $i; done
  

• Create a new empty file called /etc/puppet/manifests/site.pp and a new directory called /etc/puppet/manifests/nodes.

• Move on "scripts" directory and execute, in this order, the scripts prepare_puppetmaster.sh and generate_sitepp.py .

• Restart puppetmaster daemon with service puppetmaster restart.

• Install Nagios Server and NRPE Plugin: apt-get install nagios3 nagios-nrpe-plugin

• Move all CFG files from monitoring/nagios/config.d/ to /etc/nagios3/conf.d/

  cd /etc/nagios3/conf.d ; ln -s /data/Puppet-Shibboleth/monitoring/nagios/config.d/*.cfg .
  

• Move all CFG files from monitoring/nagios/commands/ to /etc/nagios-plugins/config/

  cd /etc/nagios-plugins/config ; ln -s /data/Puppet-Shibboleth/monitoring/nagios/commands/*.cfg .
  

• Remember to change the garr_hosts.cfg files with the hostname, and IP Address, of the Puppet Agent.

• Remember to modify the file check_nrpe.cfg like this:

  define command {
    command_name  check_nrpe_1arg
    command_line  /usr/lib/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -t 600 -c $ARG1$
  }
  

• Remember to modify the --authorization field of check_phpldapadmin.cfg file with the right credentials.

• In the end service nagios3 restart

• Install Ubuntu 12.04 LTS on the target machine: from the installation parameters, choose ONLY standard system utilities and ssh server to minimize the number of packages to be installed on the targed machine.

• Configure the network and the name resolution so that the machine reachable with its FQDN (as returned by hostname -f) from the Puppet Master.

• Install last version of puppet by executing:

  • On Debian Squeeze:

    • wget http://apt.puppetlabs.com/puppetlabs-release-squeeze.deb
    • dpkg -i puppetlabs-release-squeeze.deb
    • apt-get update
    • apt-get install puppet ruby
    • apt-get dist-upgrade

  • On Debian Wheezy:

    • wget http://apt.puppetlabs.com/puppetlabs-release-wheezy.deb
    • dpkg -i puppetlabs-release-wheezy.deb
    • apt-get update
    • apt-get install puppet ruby
    • apt-get dist-upgrade

  • On Ubuntu 12.04 LTS:

    • wget http://apt.puppetlabs.com/puppetlabs-release-precise.deb
    • dpkg -i puppetlabs-release-precise.deb
    • apt-get update
    • apt-get install puppet ruby
    • apt-get dist-upgrade

• Install Augeas 0.10.0:

  • On Debian Squeeze:

    • Add deb http://backports.debian.org/debian-backports squeeze-backports main to /etc/apt/source.list file.
    • Run apt-get update and then apt-get -t squeeze-backports install augeas-lenses augeas-tools libaugeas0

  • On Debian Wheezy:

    • Nothing because will be installed by Puppet.

  • On Ubuntu 12.04 LTS:

    • Run apt-get install augeas-tools.

• Change /etc/puppet/puppet.conf by adding the following lines at the end of file:

  [agent]
  server = <your_puppet_master_fqdn>
  report = true
  pluginsync = true
  runinterval = 1800
  
  

• Modify the file /etc/default/puppet by setting START=yes and run puppet service with service puppet start.

• After running the puppet service on each Puppet Agent, on the Puppet Master, execute this command to sign all SSH Certificate of the Puppet Agents necessary to establish their connection with Puppet Master:
  puppet cert sign --all

• Now, if you try to run puppet agent --test on each Puppet Agent, you can see if the connection is established or not with the Puppet Master.

1. Execute the script prepare_puppetmaster.sh, after have been modified his PUPPET_USER and PUPPET_SERVER variables, to generate the mandatory configurations files for your Puppet Agent (or Puppet Agents):

• the public/private keypair for the certificates to be used for HTTPs and for the IdP metadata;
• the TOU HTML file which will be presented to the user when the uApprove screen will be shown; this is mandatory only for those IdP who install uApprove software;
• a set of style customization for the user login page that includes:
• a couple of images containing the Italian and English version of the logo (they may also be equal) with the following sizes: width="32px" height="32px".
• a couple of images containing the Italian and English version of the logo (they may also be equal) with the following sizes: width="160px" height="120px".
• a CSS file.

The modules have been developed for Debian (version Squeeze, Wheezy and Ubuntu 12:04 LTS) and have been tested on an environment using the Debian Squeeze, the Debian Wheezy and the Ubuntu 12.04 LTS versions of Linux.

On the configured Puppet Agent restart the puppet service or run puppet angent --test and check that the puppet configuration works properly.

To create a machine with the Internet2 implementation of a Shibboleth IdP the following actions are requested. An example of site.pp is provided in the homonymous file in this repository. Below an example configuration that should be put into the site.pp file on the Puppet Master:

The configuration of the IdP begins with an optional configuration of iptables on the agent machine. The iptables class permits to configure a software firewall on the Puppet agent machine using iptables. This class ensures that the iptables package is installed on the system and then configures some rules to filter traffic.

The configuration pushed on each Puppet agent is a configuration which closes all ports except for ICMP traffic, port 80, 443, 8080 and 8443 (used by Tomcat and so the IdP to work properly) and port 22 for ssh. Port 22, in particular, can be configured to be open only on certain networks, specified with the $iptables_enable_network param to this class.

The iptables class has the following parameters:

• $iptables_enable_network => The network on which ssh should be accessible. If set to '192.168.0.0/24', for example, the ssh port will be accessible only by hosts with IP ranging from 192.168.0.1 to 192.168.0.254. If not set (or set to '') ssh port will be accessible by every network and every host.

Then the example provided install the common module developed by GARR for all Puppet projects related to Shibboleth. In this module the parameter that can be specified are:

• install_apache: a flag indicating whether to intall Apache httpd web server. Has to be true for Shibboleth IdP.
• install_tomcat: a flag indicating whether to intall Tomcat applicationserver. Has to be true for Shibboleth IdP.
• configure_admin: this param permits to specify if the Tomcat administration interface has to be installed on the Tomcat instance or not. If set to true the administration interface is installed and will be accessible on the port 8080 of the Puppet agent machine.
• tomcat_admin_password: If the Tomcat administration interface is going to be installed this parameter permits to specify the password for the 'admin' user used by tomcat to access the administration interface.
• tomcat_manager_password: If the Tomcat administration interface is going to be installed this parameter permits to specify the password for the 'manager' user used by tomcat to access the administration interface.
• hostfqdn: the fully qualified hostname for the IdP to be installed.
• keystorepassword: this parameter permits to specify the keystore password used to protect the keystore file on the IdP server.

• nagiosserver: This parameter permits to specify a Nagios server, if it contains a value different from undef NRPE daemon will be installed and configured to accept connections from the specified Nagios server.

After that, the example provided installs and configures the Shibboleth IdP on the Puppet agent machine. At first it installs the prerequisites needed to the IdP to be installed. Then downloads and installs the IdP Package from Internet2 Shibboleth.

The parameters that can be specified to describe a Shibboleth IdP instance are the following:

• idpfqdn: This parameters must contain the fully qualified domain name of the IdP. This name must be the exact name used by client users to access the machine over the Internet. This FQDN, in fact, will be used to determine the CN of the certificate used for HTTPS. If the name is not identical with the server name specified by the client, the client's browser will raise a security exception.
• keystorepassword: This parameter permits to specify the keystore password used to protect the keystore file on the IdP server.
• mailto: The email address to be notified when the certificate used for HTTPS is about to expire. If no email address is specified, no mail warning will be sent.
