The Official Samba-3 HOWTO and Reference Guide, John H. Terpstra and Jelmer R. Vernooij, Editors
As Linux makes its way into previously Microsoft-only environments, whether in a server or desktop capacity, it is likely that Samba becomes involved in the process of integrating the systems. Hot on the heels of the September 2003 release of Samba 3.0 comes The Official Samba-3 HOWTO and Reference Guide, edited by John H. Terpstra and Jelmer R. Vernooij, two of the cofounders of the Samba team.
The sheer amount of information in the book is impressive; the important topics of file sharing, domain control, domain membership and WINS are covered thoroughly. Beyond this, the book goes into considerable detail on issues such as security, trust relationships, access controls and system policies.
A nice touch is the presence of a number of ready-to-run sample Samba configurations in an early chapter. These range from a simple file server to a large domain controller with a directory server back end, and they are useful for anyone who quickly needs to set up a server for one of a number of common tasks, without first having to wade through hundreds of pages of documentation.
Also useful are the Common Errors sections at the end of most chapters, where many of the questions that appear time and time again on the Samba mailing list are documented and answered. These sections are of particular benefit to people migrating from an older version of Samba, and they definitely are a worthwhile feature.
Due to the complexity of modern Samba installations, it isn't sufficient for a book to cover only the Samba software itself. A number of external software packages are needed to integrate a Samba server into a large network. Fortunately, the book does not let us down. The use of OpenLDAP, PAM, ISC BIND and DHCP in conjunction with Samba are all touched on in varying degrees. A detailed chapter on using Samba with the CUPS printing system also is provided.
One minor problem concerns the chapter on configuring Windows systems, where the authors notably have omitted any explanation on joining a Windows NT 4 system to a domain, concentrating instead on later versions of Windows. NT 4 still has some corporate deployment despite Microsoft's lack of support, and potential Samba administrators may have found such an explanation useful. Interestingly, though, the authors did discuss NT 4 in a later chapter in the context of roaming profiles.
The book is unashamedly for the more-advanced Samba user. It should be appreciated most by those people who already have some experience with earlier versions of Samba or who are at least are familiar with administering Linux or UNIX systems. Newcomers looking for a book to step them through their first installation may find this book tough going; they would be better off looking elsewhere before venturing into this one. For the advanced user, however, or for anyone planning on using Samba in a production environment, this book is invaluable.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
