In Linux, setting an image as the desktop wallpaper is not a difficult task, but getting it to change automatically at a certain interval is. If you have a good collection of wallpapers and want to see them in action on your desktop, there are some nice wallpaper changer software, i’ll try to give you an overview of some of them: Desktop Drapes, Webilder, wallpaper-tray, desktopnova, wally

Suppose you have a long-running task (for example, compiling a large program) that you need to run, but you also want to get some other work done. Linux lets you start a task in the background and keep on doing other things from the command prompt. We will see in this article how to send commands in the background, then return them to the foreground, and make sure that also closing the current shell or terminal the process doesn’t remains tied to the session but continue to work. An alternative to these command is using screen, as read in a former article, but now let’s seethe command bg and the spacial character &

A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. Logically, MAC addresses are used in the Media Access Control protocol sub-layer of the OSI reference model. MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card’s read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer’s registered identification number. It may also be known as an Ethernet hardware address (EHA), hardware address, adapter address, or physical address.

In this article we’ll see 3 way of installing Ubuntu on a USB drive. We’ll see how to create a live USB Ubuntu disk, just like your live CD. Only difference is that we’ll be booting and installing Ubuntu using this live USB diskette, and as last option how to do a full installation of ubuntu on your USB drive. Option 1: Boot Ubuntu as a Live CD from a USB Flash Drive Use this option to install Ubuntu as a Live Install, which allows you to boot from the USB flash drive in Ubuntu, experience the Linux environment but will not retain any changes or settings after you shut down. This is a great way to get a feel for the OS, test some of it’s capabilities as well as typical hardware compatibility

Request Tracker, commonly abbreviated to RT, is a ticket-tracking system written in Perl used to coordinate tasks and manage requests among a community of users. RT's first release in 1996 was written by Jesse Vincent, who later formed Best Practical Solutions LLC to distribute, develop, and support the package.RT is open source (FOSS) and distributed under the GNU General Public License. Actually the stable release is the 3.8.X, and team is working on the 4.X series. I'm using RT from 2004, we have handled with it more than 100K tickets and i must say me and my company are very satisfied of this software, so i feel i can write this hub in favor of this great piece of software.

A mind map is a diagram used to represent words, ideas, tasks, or other items linked to and arranged around a central key word or idea. Mind maps are used to generate, visualize, structure, and classify ideas, and as an aid to studying and organizing information, solving problems, making decisions, and writing. Brain mapping is a graphic way to identify different parts of an issue or to plan steps or consequences of an action. Experts say mind mapping makes information easier to remember and makes studying more enjoyable.

The community of OpenOffice has highly criticated Oracle work, announcing a new name, a new project and a new foundation that will guide the project LibreOffice. The move underlines the tensions between open-source community and Oracle. Openoffice.org (originally supported by Sun Microsystems) has grown to become a real alternative to Microsoft's Office suite. OpenOffice is a real alternative to Microsoft Office, but the acquisition of Sun by Oracle has challenged the open source projects like MySQL and OpenOffice.

On linux there are some simple commands that allow you to see what the OS is seeing (that does not always correspond with the hardware in the machine). Today we will see some of these useful commands that allow you to check the proper recognition of all our devices. lspci – lsusb – lshw lspci lspci is a utility for displaying information about PCI buses in the system and devices connected to them. By default, it shows a brief list of devices. Use the options described below to request either a more verbose output or output intended for parsing by other programs.

There are many articles that explain the different characteristics of the distributions of Linux, today I also want to try it my way. If every Linux distribution was a food, which would you choose to eat? I’ll try to resume for every distro the keywords that come to my mind thinking at it and see what’s the first Food result that google image give with these words and the word food.

If you frequently use the terminals and the command line, I hope you know the command screen, otherwise get ready to see something that will help you immensely. Screen ? (from the man page) Screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells). Each virtual terminal provides the functions of a DEC VT100 terminal and, in addition, several control functions from the ISO 6429 (ECMA 48, ANSI X3.64) and ISO 2022 standards (e.g. insert/delete line and support for multiple character sets). There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows moving text regions between windows.

Last article of my series on tools for network analysis, after wireshark, ntop and a fine assortment of tools to use with the command line is the time to see nmap. Nmap (“Network Mapper”) is a free and open source (license) utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.

After ping, telnet and dig we continue to see other useful tools for network analysis done by the command line. Traceroute traceroute is a computer network tool used to show the route taken by packets across an Internet Protocol (IP) network. An IPv6 variant, traceroute6, is also widely available. The traceroute tool is available on practically all Unix-like operating systems. Variants with similar functionality are also available, such as tracepath on modern Linux installations and tracert on Microsoft Windows operating systems.

In two previous articles we saw two instruments that have as output of our analysis a graphic form (ntop and wireshark), but today we will see some tools you can use from the command line: Ping, telnet, dig, traceroute, whois, netstat, nmap, and mtr PING Ping is a computer network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer. The name comes from active sonar terminology.

wiresharkOn the Internet there are hundreds of excellent open source tools and utilities that can be used for network analysis, but not many technicians use them. Indeed, several open source solutions are truly effective and can help the specialist networks in daily work. In this first article i’ll show you Wireshark an useful tool for network analysis.

WebDAV is always been one of my favorite protocol, because it permit to easily share file system and give user the permission of upload files, on the other side using it from Linux it’s always been a thorn while on Windows it works completely integrated with the OS. What’s WebDAV ? Web-based Distributed Authoring and Versioning (WebDAV) is a set of methods based on the Hypertext Transfer Protocol (HTTP) that facilitates collaboration between users in editing and managing documents and files stored on World Wide Web servers. WebDAV was defined in RFC 4918 by a working group of the Internet Engineering Task Force (IETF).

An operating System for your kids Maybe you start thinking that after all you may begin to try Linux, I presented 27 reasons to love linux, but for your children? Well, you need a secure operating system with games that will "protect" from the net and teach them the first things on the computer world, and in general it is for their stimulating and educational ... and so, what's better than Linux! In this hub, i'll present not one but five choice between Linux distributions dedicated to childrens, each of these has been designed specifically for use by children alone, you can really tell me that Windows have the same? At the end of this short presentation I hope to consider the idea of installing one of these distributions on your old PC and give it to your son.
