Dear Readers, The September issue of BSD Magazine is dedicated to day-to-day BSD administration with the use of MidnightBSD custom installations and Live CDs, BSD server maintenance, directory encryption using PEFS and much more. We start with Rob’s column, where he discusses the future of Microsoft, the industry giant. System administrators and hobbyists often wish to build custom install media with their own software packages, or live CDs for fixing systems. In the What’s New section, Lucas Holt explores MidnightBSD custom installations and live CDs. Many sites and handbooks explain how to install servers, but once a server is running, can an administrator keep it that way? The “BSD Server Maintenance” article by Devyn Collier Johnson will cover the basics of maintaining a BSD server. Then you will have the chance to read Patrick Allen’s article entitled “Re-purposing an Abandoned Mac Mini as a Wireless Router with OpenBSD”, where he will try to bring abandoned hardware into the present with OpenBSD. Next, by reading Antonio Francesco Gentile’s article called “Monit – Monitoring Solution for Enterprise and SOHO Servers with FreeBSD”, you will learn how to set up and manage a monitoring server based on monit. In the Admin section, Rob Somerville presents the eighth part of our series on programming – “FreeBSD Programming Primer”, where we will refine our jQuery menu and start building a user friendly interface to add content. Then, Kris Moore talks a bit about Directory encryption using PEFS in the second part of his “A Closer Look at the Changes in PC-BSD/TrueOS 9.2” series. After that, Carlos Antonio Neira Bustos talks about the Z file system in his “Intro to ZFS” article. Finally, Angel Leon shows you the caveats of deploying FreeBSD over XenServer and the advantages over the traditional schema in improving administration, provisioning and delivery times. We hope you will enjoy this issue and find many interesting articles! Kamil Sobieraj Editor of BSD Magazine & BSD Team www.bsdmag.org 5 Contents Let’s Talk It’s Lonely at the Top By Rob Somerville With the imminent departure of Steve Ballmer and Microsoft insiders adamant that Bill Gates will not return, what is the future for the industry giant? What’s New MidnightBSD Custom Installations and Live CDs By Lucas Holt System administrators and hobbyists often wish to build custom install media with their own software packages, or live CDs for fixing systems. This flexibility can ease deployments in large environments or make it easy to bring your favorite OS along with you. Before customizing install media, it’s important to look at the existing build system in MidnightBSD. There are two directories within the source tree for building media, release and nrelease. Release is used to build installation media, and nrelease (which originated from DragonFly BSD) is used to build Live CDs and USB flash media. BSD Server Maintenance By Devyn Collier Johnson Many sites and handbooks explain how to install servers, but once a server is running, can an administrator keep it that way? This article will cover the basics of maintaining a BSD server. Re-purposing an Abandoned Mac Mini as a Wireless Router with OpenBSD By Patrick Allen Don’t let thousands of dollars worth of hardware that has been abandoned by Apple rot with old, unsupported software. Bring it into the present with OpenBSD. Monit – Monitoring Solution for Enterprise and SOHO Servers with FreeBSD By Antonio Francesco Gentile The state of the network services offered by a company is the business card with which it presents itself to the world. Thanks to constant monitoring, it is possible to understand how and where to improve the infrastructure of the network in real time and detect any abnormalities. Admin FreeBSD Programming Primer – Part 8 By Rob Somerville In the eighth part of our series on programming, we will refine our JQuery menu and start building a user friendly interface to add content. A Closer Look at the Changes in PC-BSD/TrueOS 9.2 – Part 2 – Directory Encryption Using PEFS By Kris Moore Last month we took a look at how PC-BSD is implementing ZFS boot-environments, which can be a life-saver for both servers and desktops. This month we will be looking at how PC-BSD uses the PEFS kernel level file system module to automatically encrypt your home directory and its contents, and how you can manually run PEFS for other sensitive data. Intro to ZFS By Carlos Antonio Neira Bustos “The Z file system, originally developed by Sun™, is designed to use a pooled storage method in that space is only used as it is needed for data storage. It is also designed for maximum data integrity, supporting data snapshots, multiple copies, and data checksums. It uses a software data replication model, known as RAID-Z. RAID-Z provides redundancy similar to hardware RAID, but is designed to prevent data write corruption and to overcome some of the limitations of hardware RAID.” FreeBSD on XenServer Angel Leon In this article, we will learn the caveats of deploying FreeBSD over XenServer and the advantages over the traditional schema in improving administration, provisioning and delivery times. 06 34 28 08 10 18 22 TM 38 42 09/2136 Let’s taLk It’s Lonely at the Top A Chief Executive Officer was newly appointed to a large public owned organisation. On saying good-bye to his predecessor, he was handed 3 sequen- tially marked envelopes and advised to open each in turn when faced with a crisis. After an initial honeymoon pe- riod, sales were down so the first envelope was opened which said “Blame your predecessor”. This worked for a while, until another major crisis arose, so the second en- velope was opened which said “Reorganise”. The CEO duly performed root and branch reform from remote site to corporate headquarters and this strategy seemed to work until another crisis emerged. On opening the third enve- lope, the CEO was greeted with the message “Prepare 3 envelopes”. While there is no suggestion that Steve Ballmer was pushed out of the role (he is retiring), the above anec- dote illustrates well the challenges of being a CEO of a major technological blue chip. You can please some of the people some of the time, but rarely all at the same time. It seems that the Microsoft Corporation (NASDAQ: MSFT) is at a critical juncture both from the long term vi- sion point of view and via strong competition in the sec- tor. Looking back to Bill Gates’ tenure, the organisation switched directions from being led by a technologist to being led by a marketeer. No doubt this made sense at the time, with the increasing move towards software be- coming just “another consumer commodity”. However, very much like Apple losing focus with the departure of Steve Jobs in 1985 and its subsequent rebirth upon his return, the strategy of running a technology company With the imminent departure of Steve Ballmer and Microsoft insiders adamant that Bill Gates will not return, what is the future for the industry giant? by a non-technologist poses some interesting questions about corporate identity and its relationship to the mar- ketplace. As the goal of any public corporation is to make as much money as possible for the shareholders, surely logic would dictate that a marketing/sales focused CEO would be the best candidate? Or maybe a banker or law- yer would be better. To the cynical, major organisations can be run by any discipline, as facilitating any effective change over the short to medium term is close to impos- sible due to cultural inertia and the sheer complexity of the business. The age old conundrum of what lead- ership model to follow is key; centralisation versus decentralisation? One large behemoth or lots of small divisions? Benevolent dictator or autonomy? Corpo- rate clone or individu- al creativity? The per- mutations are endless, as history inevitability repeats itself under each new leader. What is clear is that the original MSFT www.bsdmag.org 7 It’s lonely at the top vision of innovation is becoming decidedly threadbare. The pressure to drain every last profitable cent from the product is moving the market towards Software as a Ser- vice (SaaS). This might be fine for enterprises, but renting software will only remain a growing trend until the ever increasing pressure of vendor lock-in and the long term financial and security risk is realised by the customer. The big problem with renting anything (especially from an effective monopoly) is that they can easily dictate mar- ket price at a whim. At least if you own it (as far as you can own a software licence) you have a physical product until end-of-life. It is ironic that we have come full circle from the 1970’s where enterprises rented processing on a time-share basis. This is a very different reality from build- ing a company through innovation, aggressive acquisition and then branding the now ex-competitors’ products as your own. The disconnect is even clearer as Bill Gates’ vision of a computer on every desktop – a revolutionary idea at the time – has been such a clear success. MSFT is the dominant alpha male, effectively the industry stan- dard whether in the enterprise or in the home. All of this is set to change with the rapidly growing mobile and tab- let market, areas traditionally where MSFT has performed poorly. Time and again, the corporation has tried to gain an elusive foothold in alternative sectors without the obvi- ous success it had in the 80’s and 90’s – Bing and Nokia being good examples. In the past, MSFT managed to main- tain pre-eminence with a simultane- ous pincer attack on the enterprise and the consumer markets. This is now becoming much more asym- metrical, with MSFT holding its own in the corporate world and the consumer turning towards Apple and Android. The ques- tion is what will happen when XP finally turns end of life in 2014. Will the consumer stay with Microsoft or decide to invest in alternatives? With XP holding an estimated market share of 40%, that is a lot of legacy software – and the cool enterprise reception to Windows 8 suggests Windows 7 will become the next consumer haven. With rumours of an aggressive devel- opment cycle for Windows 9, all this may change, but it is unthinkable that the user interface will change dramati- cally from the tablet-focused model. So in the short term at least, MS has hedged their bets should their traditional domestic user base reject Windows 8 or 9 in a Vista-like fashion. Another variable is whether the consumer market will choose to upgrade their desktop PC or move towards tablets. This further plays into the hands of other players (e.g. Google docs) and weakens another traditional cash cow – Microsoft Office. Whoever leads up MSFT, it will be during a very turbu- lent and challenging time in the technology marketplace. If SaaS and the cloud continues its meteoric rise in pop- ularity, the drift away from traditional licensing/purchase models will become a stampede. This is where MS faces a huge challenge – while it might be able to get away with charging the corporate customer, anyone can easily sub- scribe to free services like CloudOn, that offers MS Office on a tablet under a freemium pricing model – free to the majority, pay for premium services. Traditionally, the MS business model would be to purchase competitors and in- tegrate, but how would they monetize this? Start charging and the user base will just move to Google docs unless they are totally locked into Office. Microsoft needs to get back to its roots and decide what business model it wants to follow. As a technology com- pany, they need a killer app, a widely adopted O/S across different platforms, and a revolutionary and exciting vi- sion. As a service provider, they need to focus on the en- terprise, especially in the area of Bring Your Own Device (BYOD) and solution/support provision. If they choose both, a fragmentation of the organisation seems inevita- ble, as the profit from traditional licensing models is evap- orating and the business models are so vastly different. Could it be that MSFT is going the well trodden path of IBM, HP and Blackberry – too big and too slow to respond to a rapidly changing marketplace and consequently los- ing their onward inertia? Unless the new CEO can pull a rabbit out of the hat, the three envelope scenario
