Must Read……

Once upon a time there was a software engineer who used to develop programs on his Pentium machine, sitting under a tree on the banks of a river. He used to earn his bread by selling those programs in the Sunday market.

One day, while he was working, his machine tumbled off the table and fell in the river. Encouraged by the Panchatantra story of his childhood
( the woodcutter and the axe )
He started praying to the River Goddess. The River Goddess wanted to test him and so appeared only after one month of rigorous prayers. The engineer told her that he had lost his computer in the river.
As usual, the Goddess wanted to test his honesty. She showed him a match box and asked, ‘
Is this your computer ?
‘ Disappointed by the Goddess’ lack of computer awareness, the engineer replied, ‘ No.’

Safe Orkuting

1.Try to use Mozilla Firefox or opera or Apple safari as they have very few security vulnerability as compared to the Internet Explorer 7, which is full of well known security vulnerability. Although I have never tried Internet Explorer 8.

2.Never download or activate the grease monkey extension in Mozilla Firefox while orkuting because it may run malicious Java script without your permission leading to your private data export to the hacker.

3.Never click on malicious link or catchy photos from inside your Orkut windows as they lead to almost most of the Orkut hacks.

DSpace Redeployment

Redeployment of the DSpace Server

Read this blog if you want to upgrade DSpace from Lower Version to Higher.

1.Current Version running at the University Resource Center is Dspace-1.4.1

2.Current Available Version Dspace-1.4.1.

3.Roadmap :

1.First of all take the backup of the URC Server
2.Restore the that data on another system.
3.Upgrade the version to 1.5.2 on that computer.
4.Testing the system after up gradation
5.Testing in Real Environment
6.Redeployment

Fedora Repository

1 Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.

We want to make the yum repository accessible through http; Apache’s default document root on Fedora is /var/www/html, so I’ll create the repository in /var/www/html/yum. If you’re using a different vhost, you might have to adjust the paths.

Slim Server

This is my first blog so, don’t expect my blog to be free from english mistakes because technical guys are generally weak in communication and litreary .This first blog is about how to install the SLIM server which stands from Single Linux Image Management.Basically this is a article which I really found very much interested as a FOSS Lover……………..

A. Introduction

A Linux cluster is considered a single system which consists of a set of tightly coupled machines called nodes. In many cases, it is locked inside a room and people access it remotely via the network. Usually nodes are individually installed with the Linux OS manually. This creates much setup burden when the number of nodes is large.

SLIM (Single Linux Image Management) is a solution developed by the Department of Computer Science of HKU to ease the deployment and management of large-scale networked Linux systems. One of the goals of SLIM is to reduce the setup burden. This workshop teaches you how to setup, administer, and manage a SLIM environment for cluster computing. More information about SLIM can be found at the website http://slim.cs.hku.hk/.

The SLIM environment consists of a SLIM server to provide shared system resources via the network to the client PCs. Client PCs known as cluster nodes use network booting to start the Linux system locally.

In this workshop, we will use the Fedora Core 2 Linux distribution to setup the SLIM server to serve all the cluster nodes connected in a network. Figure 1 depicts the specific network topology we will use in this workshop.

The SLIM server is on the 10.0.1.0/255.255.255.0 private network. The IP address of the SLIM server is 10.0.1.254. This is the simplest form of the SLIM environment network. But it is powerful enough to build a Linux Cluster having tens of cluster nodes.
