In these days i’ve worked a lot on Red Hat Enterprise and Centos machines, and so i’ve used yum to install, upgrade, remove and download packages.
I’m more used to .deb packages (or the portage system), and so for me these plugins are both new and really useful to extend the basic functions of yum.
In particular i’ll show you how:

Have you accidentally deleted an important file because you are in a habit of using “Shift+Del” rather than delete only?? Well don’t panic. There is a utility named as “scalpel” which helps you in recovering the so called “permanent deleted” files. Actually when you delete a file permanently (Accidentally or By Intention) , It doesn’t get removed from your hard disk. It get stored in certain blocks of the storage device and they continue to exist in the blocks unless you overwrite them with another files. This article will talk about utilities that will help you in the file recovery. It is always recommended that you shouldn’t recover a file from the device when it is mounted. You should always do the recovery process with the Live CD followed by the file searching in the device like in my case device is /dev/sda1 . If you are unable to understand the upper condition, just forget about it. I am not going to bore you with the theory part anymore. Let’s take a look at the utility.
Yesterday I’ve done an introduction to EncFS, a Free (GPL) FUSE-based cryptographic filesystem that transparently encrypts files, using an arbitrary directory as storage for the encrypted files. i’ve show how install and use it from the command line, but there is also an easier way to integrate it with your Desktop: Cryptkeeper.
Cryptkeeper is a Linux system tray applet that manages EncFS encrypted folders.
EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. EncFS is open source software, licensed under the GPL.
As with most encrypted filesystems, Encfs is meant to provide security against off-line attacks; ie your notebook or backups fall into the wrong hands, etc. The way Encfs works is different from the “loopback” encrypted filesystem support built into the Linux kernel because it works on files at a time, not an entire block device. This is a big advantage in some ways, but does not come without a cost.

In the 2 former articles of this series we have saw OCSInventory and Fusion Inventory 2 software that can create an asset inventory with your computers hardware and software, they both work with agents on the remote machines that send the information on a central server, where you can see, manage and query these information.
Today i present you GLPI, another French product, that can use both of these Inventory solutions and add on top of them a lot of useful things, like an embedded Ticketing System, a Financial Management for the assets and It has enhanced functions like a job-tracking system with mail notification and methods to build a database with basic information about the network topology.
