Shibboleth is a free open source implementation for identity management, providing a web-based single sign-on mechanism across different organizational boundaries. It is a federated system, supporting secure access to resources across security domains. Information about a user is sent from a home identity provider (IdP) to a service provider (SP) which prepares the information for protection of sensitive content and use by applications. If you are not familiar with Shibboleth and how it works, you may be benefited from the Shibboleth home page. In this tutorial we will cover installation of the IdP first and then we will perform the necessary configuration to customize the IdP for an organization. Afterwards, we will install and configure the shibboleth SP and will setup a basic scenario to protect a resource.
IdP Installation This is an installation guide to setup an IdP with the basic features. For a detail introduction to the identity provider or Shibboleth, please refer to Understanding Shibboleth. This tutorial uses CentOS 5.6 as the OS for IdP server. » Read more…

In this article I will introduce the reader to private cloud computing while discussing the nature of a private cloud with UEC based Eucalyptus as a case study to maintain order.
A private cloud is a cloud computing infrastructure implemented as a service provider rather using a public cloud as a consumer of the service.
The main aspects that sets private clouds apart from a commercial public cloud is where the infrastructure is implemented and how it is deployed and maintained. A private cloud is typically hosted on the company servers within their own network infrastructure and administrative domain. » Read more…
CSRDU has just released its first open source contribution through sourceforge.net. It’s a PHP-based script (plus a dialplan) for sending fax through asterisk from a web interface. You can read more about it on my blog here.
In this video, we talk about Auto Scale feature of the Elastic Compute Cloud (EC2). Auto Scale allows AWS to automatically start new instances of AMIs as more and more load is put on the instance. You can define triggers (policies) that define what the low and high limits are. Whenever these limits are breached, instances can be started or stopped depending on the policies. In this video, we start from scratch and setup the Auto Scale feature.
All comments are welcome.

The first in a series of videos by CSRDU about Amazon Web Services (AWS). Here, we talk about the different web services and technologies offered by AWS. It’s supposed to make sense of the different services that AWS offers and whether you need them or not. (Click to view larger version on YouTube)

PostgreSQL is an opensource and free-to-use Object-Relational Database Management System (ORBMS) and is controlled by a group of developers and development companies. PostgeSQL has three modes of backup, i.e. dump, dump all and Write Ahead Log (WAL). I would not focus here on the difference between the three, but will introduce WAL of postgresql. Write Ahead Log is a section of Postgresql where all the psql commands that have been executed are stored. Creating a copy of these logs and executing them again will restore any crashed database. This method is called Point-in-Time recovery, where WAL’s from a certain point in time are re-run to restore (crashed or lost) databases. The tutorial will walk you through the important steps for both backup and recovery of postgresql database using this method.
As an added activity at CSRDU, we’ll be posting links to tutorials that different CSRDU members have written. These are different from ‘contributions’ to CSRDU that are edited and posted in full on our own site.
Here’s the first set of tutorials that might be considered more general purpose. Many members have written tutorials that are very useful from a research perspective and we will try to include them in further posts inshallah. For now, enjoy the first set of more general tutorials that might be useful for a much wider community. You can always comment on the original posts (or even here) to ask questions about the tutorials.
An initial CSRDU strategy meeting was held last week where we discussed some very important matters regarding the present and future of CSRDU. We came up with some important points about the goals, objectives and working of CSRDU. To facilitate a transparent working system, we’re posting this information on our blog so that newcomers can better judge how their interests can align with our goals. Remember, though, that CSRDU is a work in progress. All comments, criticism and suggestions are more than welcome. Please raise your voice if you have something to say. We would be glad to listen if there’s even the slightest chance it can lead to improvement. » Read more…
