Due to known issue attempt to virt-install OpenSuse 11 PV DomU at Xen 3.3 CentOS 5.2 Dom0 from nfs share fails immediately at startup. Approved procedure via Internet repositories for OpenSuse 10.3 requires internet connection speed at least 700 Kbit/sec to take reasonable time. OpenSuse 11.1 (with pygrub implemented) is due only in December 2008.However, pygrub coming along with current Xen Release 3.3(3.2.1) does allow to load OpenSuse 11 DomUs at CentOS 5.2 (RHEL 5.2) Dom0 with no problems.

With libfaketime you can tell a process that the current time is something different from the machine's system clock. This fake time setting affects not only the functions directly related to reading the system time, but also file timestamps such as modification times. With libfaketime you can test how a program will respond when it is running in the future or in a different timezone without having to change your machine's system clock. Timezone testing can be useful for network applications where a certificate may have already expired in a given timezone but might still work in your local environment.

In this article I'll briefly review ten of my favourite CLI (command-line interface), not necessarily the most popular or most powerful of them. So if you don't find your personal favourite, (e.g. Midnight Commander or mp3blaster), it's because the article includes the tools I use more often. So here it goes:

In part one of this tutorial I looked at installing and configuring greylistd alongside Exim to help combat the evils of Spam. In this second part I will look at getting some information out of greylistd — handy if you need to troubleshoot why the CEO’s “urgent” message hasn’t arrived yet! Read Part Two of Ryan Cartwright's article on Exim and greylistd at Freesoftware Magazine.

When you think Red Hat, you think Linux. Maybe, if you're a developer or a CTO, you also think JBoss. Red Hat, itself, now wants you to think virtualization.

This article by Tarek Ziadé focuses on a repeatable process to write and release Python packages. We will focus on how to install, uninstall, develop, test, register, and upload a package.

I have one last item I would like to discuss pertaining to the use of html forms. That is, the question on how to store unvetted, input data. I will show it makes sense to store the news items as formatted, ready to publish summaries as separate text files each containing one story. I further suggest they be deposited in an off site directory with severely limited access rights. The formatting for news items is simple, using either a template or an informed (trained) user. I show how I would have implemented a simple file naming structure to make news items easier to work with in an inherently date / time ordering. For this particular, limited instance, I think my model would have worked.

If imitation is the sincerest form of flattery, then the Linux community must be doing something right. Rumors abounded throughout the blogosphere last week that HP may be working on its own version of our favorite operating system. Specifically, employees within HP's PC division are reportedly working on a mass-market operating system that is based on Linux but easier to use.

Amarok sure inspires a lot of KDE-envy for Gnome users. Unfortunately, it doesn’t fit in well in Gnome: it’s written for a different desktop environment, uses a whole different toolkit, and requires a lot of extra libraries to run. Luckily, there’s a great Gnome-based alternative: Rhythmbox. Andrew Min at Freesoftware Magazine explores the Gnome alternative to amarok. You can read the full article at FSM.

Mail merge, the production of multiple documents that differ only in minor details, remains a difficult task in OpenOffice.org Writer. Few use the function regularly, and when they do, the mail merge wizard seems to cause as much confusion as it resolves. Writer's original mail merge feature, retrievable from Tools -> Customize -> Add -> Documents -> Mail Merge is somewhat more straightforward, but, even with it, users are likely to confuse the original document and the information source. In comparison to those other alternatives, FastMailMerge is not only simplicity itself, but a welcome relief that easily lives up to its name.

13 terminal emulators for Linux: Konsole, GNOME-Terminal, Yakuake, Tilda, ROXTerm, xterm, Eterm, xvt, rxvt, mrxvt, rxvt-unicode, aterm, wterm.

Traditional methods of spam protection involve using Bayesian detection rules (usually via SpamAssassin) on messages after they have been accepted by your server. Most mail sysadmins may have encountered the constant cries from their users asking “can’t you stop them sending it?”. Of course you can’t stop somebody sending a message but you can stop accepting them in the first place. Enter greylisting. These two articles are kind of follow-ons to my previous article on spam prevention in exim mail servers. Think of it as an appendix. If you are starting from scratch you might find is useful to go and read that first. Read Ryan Cartwright's article in full at Freesoftware Magazine.

This howto explains installing Zivios Master Service version 0.5.0. Zivios is an n-tiered PHP-5 application, providing identity management, single sign-on, user, group and computer provisioning, as well as remote management of services. It uses MySQL and OpenLDAP as its data store, with OpenLdap being the primary back end for identity management and application integration and MySQL being used for panel specific data.

Microsoft's new "I'm a PC" ad campaign celebrates the fact that millions of people prefer PCs over Macs. But it overlooks the fact that many of those PC users are leaping from Windows to Linux. For me, "I'm a PC" means I've discovered the freedom of open source.

Toshiba has announced that it too is joining the “Netbook” race, but given that the Intel Atom is a chip designed for exactly this type of low-spec computer, what’s more of a surprise is that it has taken Toshiba this long to join in the fun!

Postfix Mail Server will allow you to set a base domain and add any number of virtual domains. Virtual domains can either be virtual alias domains which are the domains that your server is the final destination for and also virtual mailbox domains which do not have local accounts and only pick up mail through IMAP or POP3.

A quick script to pull up famous quotations based on keywords or phrased you provide on the Unix or Linux CLI. Today's Linux/Unix bash shell script is yet another follow up to a whole cavalcade of scripts we've written to mine the knowledge on tap at reference.com, although this one is grabbing its material from QuotationsPage.com. If you missed any of the others, you can still find them in our older bash script posts to do encylopedia lookups, access the online Thesaurus, translate between different languages and, of course, the use the online dictionary.

Javier Colado, Novell's new channel chief, tells The VAR Guy that he has some new ideas to help strengthen Novell SUSE partner relationships. Here's a look at the first interview published with Colado.

Sometimes sharing files and folder between Windows and GNU/Linux can be annoying and problematic especially for beginners. In this article we're going to see how to setup Samba and how to get both Windows and GNU/Linux sharing and browsing public share the right way.

This review has been a long time coming...mainly because I've been having such a good time with this book. That said, the title is a bit misleading. It's not really "The book that should have been in the box" (even if JavaScript came in a box) since a "box of generic JavaScript" wouldn't have come with half of what this book contains. In fact, I'm not really sure the reader will come away with a solid foundation in JavaScript after reading McFarland's book. Let me explain.
