The Fat Bloke Sings About VirtualBox

One of my favorite bike builders is Russell Mitchell, owner of Exile Cycles. He designed and his crew builds bikes like the Fat Bloke pictured above. You can buy the bike already built like the movie stars do, or initiate yourself into the world of old-school motorcycling by building it yourself from parts in Russell's shop.

Here's another Fat Bloke that's got something interesting to offer. Migrating from VMWare to VirtualBox with Oracle Enterprise Linux describes how to move a virtual machine from one virtualization platform to another. Kinda like moving your hard drive from one machine to another, as the Fat Bloke puts it. Or swapping out the engine on Exile's Brown Pearl and dropping it into the Hot Rod. Or, God-forbid, a Honda Gold Wing.

The writeup by Fat Bloke the blogger includes these topics:

  • Preparing to Migrate
  • Exporting the Virtual Machine
  • Importing into VirtualBox
  • Installing the VirtualBox Guest Additions
  • An Alternative Approach for Advanced Users
  • My favorite of Russell's bikes is the Silver Bullet, though the Brown Pearl is a close second.

    Great New Article on Oracle Solaris 10 Security


    In "Using Oracle Solaris 10 to Overcome Security Challenges," Mark Thacker describes how Oracle Solaris 10 uses the principle of least privilege to reduce the vulnerabilities of applications that perform privileged operations as root.

    "Over 65 discrete, fine-grained privileges are built into the kernel and user access space. The concept of privileges as implemented in Oracle Solaris 10 is extended throughout the operating system — even the built-in tools take these rights and privileges into account. Using this approach, administrators can grant new or existing applications only the appropriate privileges necessary to perform tasks. Many system components such as NFS, the Oracle Solaris Cryptographic Framework, IP Filter, file system mount commands, and more, are already configured to run with reduced privileges by default, with no configuration required by the administrator.

    Mark goes on to provide clear explanations of how the following Solaris 10 security features work:

    • User Rights Management (role-based access control), which an administrator uses to limit access to administrative functions while providing access to specific operating functions.
    • Network Security and Encryption, which includes Secure-By-Default (one of those "Duh, why didn't I think of that" ideas), IP packet filtering firewall, an integreated cryptographic framework, and an arsenal of other tools that sysadmins can use to both keep out network intruders and comply with privacy regulations.
    • Minimized and Hardened OS, which reduces the size of the target for hackers by only installing basic features and securing them at the same time.
    • Containers and Trusted Extensions that enable sysadmins to isolate and protect applications and users in a virtualized environment.

    This article is clear, easy to understand, and does a great job of explaining exactly how an admin can use the security tools of Solaris 10 to protect and certify an operating environment.  Includes a solid list of security resources.

    I found the picture of the bull in this BBC story.
