For those who have been handed the keys to a system and simply been told, “It’s not working”, it can be very useful to know what files have been modified from the stock installation of the system.

If you are working with an RPM-based installation, such as Suse Linux Enterprise Server, the following command (by way of Linux Journal) can be very useful:

rpm -qa | xargs rpm --verify --nomtime | less

This command will spit out output that looks roughly like this:

missing     /usr/local/src
  .M......    /bin/ping6
  .M......    /usr/bin/chage
  .M......    /usr/bin/gpasswd
  ....L...  c /etc/pam.d/system-auth
  .M......    /usr/bin/chfn
  .M......    /usr/bin/chsh
  S.5.....  c /etc/rc.d/rc.local
  S.5.....  c /etc/sysctl.conf
  S.5.....  c /etc/ssh/sshd_config
  S.5.....  c /etc/updatedb.conf

A quick look through the man pages will tell you what the flags mean:

  c %config configuration file.
  d %doc documentation file.
  g %ghost file (i.e. the file contents are not
    included in the package payload).
  l %license license file.
  r %readme readme file.

  S file Size differs
  M Mode differs (includes permissions and file type)
  5 MD5 sum differs
  D Device major/minor number mismatch
  L readLink(2) path mismatch
  U User ownership differs
  G Group ownership differs
  T mTime differs

So, in our sample output you can quickly determine that the configuration file for the OpenSSH daemon (/etc/ssh/sshd_config) has been modified, along with several others.

This can give you a quick insight into the state of the system, and may allow you to trace down the source for any errors more efficiently

On Tuesday, June 30th from 1-3 EDT we will review the primary method of managing resources (CPU, memory, disk, network, etc) in SUSE Linux Enterprise Server 11, Control Groups in a live online webcast.  Control Groups are a new feature that can help you manage which applications have access to specific resources, and how much of those resources applications can consume.

By using PlateSpin® Orchestrate to manage both Microsoft Windows and Linux environments, Tenzing has created a new cloud computing platform for a new market of customers.

Tenzing is a managed hosting company with an award-winning approach to hosting business-critical Internet applications. A private company with 60+ employees, Tenzing has customer service centers in Kelowna, BC and Toronto, Ontario and datacenters in Canada’s primary NAPs: 151 Front, Toronto and the Harbour Centre, Vancouver.

Challenge

As a managed hosting company, Tenzing manages the complex business requirements of hundreds of different clients. To provide efficient services and support, the company needs to make the best use of its data center resources. Automating workload management across physical and virtual machines would not only increase efficiency and improve performance, but also reduce costs for both Tenzing and its customers.

Many of Tenzing’s clients have both Microsoft Windows and Linux environments and require virtualization technologies that work seamlessly on both platforms. Tenzing needed a single data center management solution that was flexible enough to natively manage all industry-leading hypervisors, including VMware, Xen and Microsoft Hyper-V.
Novell Solution

Tenzing evaluated several workload management solutions including VMware and Citrix, before selecting PlateSpin Orchestrate from Novell to power its new cloud computing platform.

“We needed a workload management solution that is hypervisor agnostic,” said Kelly Beardmore, CTO at Tenzing. “PlateSpin Orchestrate is the only solution we evaluated that does not lock us in to a single virtualization technology, giving us the maximum flexibility to meet the individual needs our diverse customer base. We also found that PlateSpin Orchestrate was very extensible and easy to customize.”

Using PlateSpin Orchestrate, Tenzing can manage client workloads efficiently across physical and virtual machines. The company can effectively leverage all hypervisor technologies, regardless of vendor, and manage everything from a central, unified interface. With a centralized view of its data center, Tenzing can create policies specific to a customer’s business environment. For example, if a customer has a significant outage, policies automatically direct the workload to another machine, with no user disruption.

“We need a flexible policy engine and the ability to set high-level policies for our clients, regardless of the technology underneath,” said Beardmore. “PlateSpin Orchestrate is the brain of our data center and allows us to manage workloads effectively so that everything works in concert. We can tailor policies for hundreds of customers.”

PlateSpin Orchestrate offers high levels of automation, allowing Tenzing to quickly provision new servers using images and predefined templates. Such automation has dramatically improved speed of delivery – the company can now deliver solutions to customers in 15 minutes, a process that used to take up to 24 hours. PlateSpin Orchestrate will also automate the way customers place orders as they will be able to elastically scale their network, storage, and processing resources on-demand through a Web-based portal.

“With PlateSpin Orchestrate, we do the initial install of the operating system and application framework for our customers, then they configure it and we template it,” said Beardmore. “If there is a problem, we have the template ready which greatly reduces our support costs.”

PlateSpin Orchestrate provides Tenzing with the flexibility to balance the right amount of computing resources for each customer. Such flexibility also allows the company to prevent any business disruption in the event of a workload failure. Customers can be confident that they can scale workloads on demand in both their Windows and Linux environments.

“With PlateSpin Orchestrate, we’ve been able to bring a cloud computing platform to the market, which is an important place to be right now,” said Beardmore, “We can be much more flexible than our competitors with the ability to provide native support for Windows and Linux, using any hypervisor technology.”
Results

PlateSpin Orchestrate gives Tenzing a single workload management tool to natively manage Windows, Linux and VMware environments, enabling the company to create a cloud computing platform to reach a new market. The flexibility of the solution allows the company to effectively support the individual needs of its diverse customer base.

Automation has dramatically improved data center efficiency, while reducing man hours by 50 percent. The company can now deliver services to its customers 95 percent faster. Greater efficiency has also reduced capital expenditures per customer deployment by 20 percent, and support costs by 25 percent. With flexible, monthly licensing agreements from Novell, the company can pass along savings to its customers with cost-effective options.

“Without Novell, we would be tied to specific technologies—whether Microsoft, Xen, or VMware—and would be forced to manage each environment separately,” said Beardmore. “PlateSpin Orchestrate gives us a major competitive advantage as we can provide customers with a much more flexible offering as there is no need to require customers to use one solution over another.”

A nice little article about LA-based chain La Curacao who worked with Novell partner Novacoast to test and implement SUSE Linux Enterprise Server and other solutions to alleviate problems they were experiencing and better position themselves for growth.

In addition to being affordable, La Curacao now has an IT environment that is largely hands-off and maintenance-free. “It all works the way it’s supposed to,” Elder says. As a result, the time spent administering the system has dropped by about 50 percent, leaving IT employees more time to focus on other projects.

Before we start our journey to Linux land there is one question you need to ask yourself: why do YOU want to switch from Windows to Linux? What do you expect Linux to achieve? You don’t want to spend the time and effort learning about Linux just to realize that changing your operating system to Linux does not solve the problem you have or does not deliver the benefits you expected.

I will list 9 of the most common reasons to switch from Windows to Linux and try to explain in which cases the switch to Linux has a good chance of delivering the expected benefits.

From the article:

British market researchers took some lessons from a survey of 1,275 Linux migrators in organizations worldwide.

The respondents considered the fear of “painful and distracting” change as the largest obstacle to migrating from Windows to Linux. Device driver issues, fragmented distributions and lack of support were not among the high potential hurdles, according to the study.

Oh boy, this will cause some, umm, “lively discussions”, this guy details why he switched from GNOME to KDE. From the article:

Three weeks ago, I switched my main desktop from GNOME to KDE. The switch was not a rejection of GNOME, nor an unreasoning enthusiasm for KDE. It was based on my determination to learn about a side of GNU/Linux that I had been partially neglecting, and a growing appreciation of KDE’s innovations on the desktop. And, thanks to the attitudes that GNU/Linux has taught me, the switch needed almost no adjustment period, either.

The truth is, I had been tempted to make the switch for fifteen months, ever since I saw the finished KDE 4.0 in January 2008. One or two aspects of KDE 4, such as the separate mode for customization and the de-coupling of the desktop from the file manager had immediately intrigued me. I was less thrilled about other changes, such as the Kickoff menu, but even these suggested a philosophy of advancing the desktop without breaking with tradition — an attitude that struck me as exactly right.

Check out the newly launched Linux.com site run by the Linux Foundation. It would be nice if their vision came true…

SAN FRANCISCO, May 13, 2009 — The Linux Foundation (LF), the nonprofit organization dedicated to accelerating the growth of Linux, today announced the formal launch of Linux.com. The Foundation took over stewardship of the site in March, at which time it began soliciting input from the community to help define the new Linux.com via its Ideaforge web tool. Today, it unveils the results of that input and a new online home for all things Linux.

The new Linux.com will connect Linux users and developers, and by showcasing their skills through its guru listing, will connect individuals to jobs and collaboration opportunities. Instead of a static information site, the new Linux.com will empower the Linux community to share its knowledge, get questions answered, download the right software and find hardware to solve problems.
