I liked from the beginning the idea behind Bodhi Linux and so I followed the progress of this young version of Linux and take advantage of version 1.0 (congratulations to Jeff and the entire team) to make a review. For the uninitiated Bodhi Linux is a recent project that taking as a base Ubuntu 10.04 “reconstructs” the Enlightenment desktop, it use the login system manager of LXDE (and also as the terminal) and offers its own package system (.bod); The system being based on Ubuntu is still compatible with .deb and dpkg and aptitude can be used without problems.

Gmail has become for many the favorite e-mail account, being very comfortable, with plenty of space available and a web interface that can be used through various devices: smartphone, laptop or desktop. But I guess that all of you know already all the advantages of using these email accounts so that they are becoming very important for us … but have you ever thought about making a backup of these mails?

In this article you will see how to configure a service with Spamassassin to identify and discard spam on your mail server.

When a server environment is created using virtualization software or a cloud service, the number of servers tends to increase rapidly. Software installation and configuration are required every time a server is created. Further, synchronizing server configurations requires additional effort such as writing shell scripts.

In this article, we will describe how to build a server environment automatically using a relatively new software tool called Puppet.

If in your work you are responsible for just one server, you will surely wonder: What is the best way to get the situation under control? In the world there are good open source software that allow you to monitor the status of servers, services and programs. In this article we’ll see an overview some of the softwares in this category, and in particular some related to Nagios

Today i want to show you some examples done with Zenity. Zenity is a cross-platform program that allows the execution of GTK+ dialog boxes in command-line and shell scripts. Like tools such as whiptail and dialog, zenity allows for easy creation of GUIs, though it has fewer features than more complex GUI creation tools.

After the upgrade to 10.2 i’ve ran in a know Flash bug and now i can see youtube only in black and white, i’ve searched the net a bit and i’ve found that’s a common problem. The cause seems to be a combination of Flash 10.2, a recent YouTube change and the users graphics cards and seems to be browser-independent (can occur in Firefox 3.x, Firefox 4 beta as well as Chrome / Chromium). Personally i’m a bit tired of all these flash issue, and while waiting for html 5, i’ve took a look around to try some alternatives and in particular for youtube I’ve found minitube.

FFmpeg can be considered the Swissknife of audio and video applications, with many options and possibilities. You probably already have it installed on your computer as a dependency of a program you use to watch videos or listen to music. In this article we will see some use from the command line without using graphics applications.

IPTState is a top-like interface to your netfilter connection-tracking table. Using iptstate you interactively watch where traffic crossing your netfilter/iptables firewall is going, sort by various criteria, limit the view by various criteria. But it doesn’t stop there: as of version 2.2.0 you can even delete states from the table!

This program is an “inotify cron” system. It consists of a daemon and a table manipulator. You can use it a similar way as the regular cron. The difference is that the inotify cron handles filesystem events rather than time periods.

A configuration management database (CMDB) is a repository of information related to all the components of an information system. Although repositories similar to CMDBs have been used by IT departments for many years, the term CMDB stems from ITIL. In the ITIL context, a CMDB represents the authorized configuration of the significant components of the IT environment. A CMDB helps an organization understand the relationships between these components and track their configuration.

Open source is very dedicated in sharing information, comparing and learning, then in this article i will recommend some readings of open books that you can download, read and if you want print freely.

The script command is part of the util-linux-ng package and so should be available already installed in any distribution, or you should be able to easily add it.

Yesterday I followed the online event Virtual Experience, presented by Red Hat. The event was presented in 4 main areas :Red Hat Enterprise 6, Cloud Computing, Virtualization and Jboss, for an idea of the sessions available take a look here. I followed some of the sessions and from what I saw I had the impression that Cloud is the key word (or fashion) that is often repeated even in talks about other topics, RH surely is betting a lot there, but we are still in the early phases and there are enabling technologies, but the solutions must be built ad hoc on your infrastructure.

Are you afraid that your system has been compromised by an unauthorized access? Have you got discovered abnormal network activities and/or do you suspect that your system has been infected by trojans or rootkit? Is this your nightmare? ;) No problem, there are some solutions which help system administrators to check their servers, so they can be more serene about security of their machines.

Awk has always been for me a source of great hatred and love, its an incredibly powerful command with which it is possible to build real programs. In this article I will give you 6 examples ready for use with your preferred terminal. Awk is a data driven programming language designed for processing text-based data, either in files or data streams. It is an example of a programming language that extensively uses the string datatype, associative arrays (that is, arrays indexed by key strings), and regular expressions.

As first thing i want to say that i’m not so well informed about the background of the Mono project, his licenses model and possible implications, and I’m trying to get an idea after reading a few posts on techrights.org. In fact I read on techrights very strong words against this project, and so I’m trying to understand something more.

What better time to create your own calendar for 2011, even better if based on the Linux world? I saw this idea on the site http://cursorlibre.com/ where they made a nice dodecahedron with a Ubuntu theme. In the download package, there is a pdf version ready to print and assemble, plus a pdf version of a guide in which is explained what parts should be cut and how to bend the paper to obtain the dodecahedron.

Actually, I tried them all, from the mythical Beagle to Tracker. Beagle is now in effect a dead project. It was quite interesting, able to search many types of files and miscellaneous information, but personally I was not willing to use so many resources for Mono. Patience, they had developed from the outset with the standard libraries perhaps it might be on all computers. I tried other less known programs, Catfish, Pinot and some other that escapes me, cursed memory, up to lead to Tracker a searching program for files (and information) for Gnome. Until version 0.6 it seemed that someone had finally decided to engage seriously in the implementation of a program that allowed me to not always use the memory to remember which file or e-mail contained the information i was searching for. I was promptly denied (and betrayed).

One thing I found very interesting about Linux is the ability to have a whole series of classic games already present on your distribution, and therefore easy to install. What do I mean as classic game? Games released prior to 2000 on Amiga or perhaps on other operating systems and now ported to Linux. Follow me in this series of old games (as a concept), but always enjoyable and funny.
