    OpenBSD Mastery: Filesystems

    “Many users assume that their advanced filesystem is better than UFS because they have so many features—snapshots, checksums, compression, sophisticated caching algorithms, and so on—while all UFS has ever done is muck about putting data on disk. But, conversely, UFS users believe their filesystem is better for exactly the same reasons.”
    —Hitchhikers Guide to OpenBSD

    FreeBSD Mastery: Jails

    CONFINE YOUR SOFTWARE

    Jails are FreeBSD’s most legendary feature: known to be powerful, tricky to master, and cloaked in decades of dubious lore. Deploying jails calls upon every sysadmin skill you have, and more—but unleashing lightweight virtualization is so worth it.

    FreeBSD Mastery: Jails cuts through the clutter to expose the inner mechanisms of jails and unleash their power in your service. You will:

    FreeBSD Mastery: Jails

    • Understand how jails achieve lightweight virtualization
    • Understand the base system’s jail tools and the iocage toolkit
    • Optimally configure jail hardware
    • Manage jails from the host and from within the jail
    • Optimize disk space usage to support hundreds or thousands of jails
    • Comfortably work within the limits of jails
    • Implement fine-grained control of jail features
    • Build virtual networks
    • Deploy hierarchical jails
    • Constrain jail resource usage
    • And more!

    Strip away the mystery. Read FreeBSD Mastery: Jails today!

      Absolute FreeBSD, 3rd Edition

      FreeBSD empowers. Absolute FreeBSD empowers absolutely.

      The critically-acclaimed FreeBSD guide, now expanded, revised, and updated!
      Absolute FreeBSD 3rd Edition cover

      “When was the last time you could physically feel yourself getting smarter while reading a book? If you are a beginning to average FreeBSD user, Absolute FreeBSD 2nd Ed (AF2E) will deliver that sensation in spades. Even more advanced users will find plenty to enjoy.”
      Richard Bejtlich, TaoSecurity founder and president

      FreeBSD is the muscle behind companies from Netflix to EMC. Any place where someone does heavy lifting on the Internet, you’ll find FreeBSD. Absolute FreeBSD brings FreeBSD’s strengths to bear on your problems.

      Any computer system is only as good as the system administrator’s knowledge. Absolute FreeBSD teaches you everything you need to know about managing FreeBSD systems, from installation, configuration, and taking the system from “just working” to “working well.” A cohesive focus on service delivery and best practice means that you can apply much of the book to other operating systems.

      ” . . . a very fine piece of work. It isn’t about how to implement BSD solutions. It’s about managing systems ‘in situ.'”
      –Peter Salus, UNIX historian, on the 1st edition

      Managers ask “Why is it slow?” “How fast is it working?” “How many users can our current hardware handle?” Sysadmins ask “Can I set up a local software package repository?” “Where is that function, anyway?” “What do I do with this crash dump?” Absolute FreeBSD, from No Starch Press, answers these and more!

      Absolute BSD taught new sysadmins how to build and manage a FreeBSD server. Absolute FreeBSD dove deep into server management, taking you beyond just making things work and into understanding why they work. This third edition of Absolute FreeBSD updated all that knowledge and covers FreeBSD’s newest features.

      You’ll learn:

      • How to best install FreeBSD to meet your needs
      • Which filesystem to use in your environment
      • How to back up and restore critical data
      • When and how to tweak the kernel, and when not to
      • Network configuration, from activating interfaces to selecting congestion control algorithms
      • Managing both UFS and ZFS, as well as FreeBSD’s other important filesystems
      • FreeBSD’s software packaging system, including how to build your own package repository
      • How and when to upgrade
      • How to build your own FreeBSD
      • Advanced security features like blacklistd and packet filtering
      • Monitoring and Adjusting Performance
      • Container-style virtualization with jails
      • Diskless systems
      • Panic management and bug reporting

      New readers will still get the solid introduction they need, but fans of the earlier editions will expand their skills still further.

      All in the inimitable style that has made Lucas’ system administration books so popular.

      Absolute OpenBSD, 2nd Edition

      OpenBSD is the world’s most secure networked operating system, in wide use by Internet Service Providers, corporations, and embedded systems manufacturers. The original Absolute OpenBSD was the go-to work on this operating system, earning praise for a decade after its release.

      Absolute OpenBSD 2nd Edition coverThe best-selling standard work on OpenBSD, fully revised and expanded!

      The first copy of Absolute OpenBSD off the press was auctioned off to support the OpenBSD Foundation.

      This new edition is fully rewritten and contains the latest details about key OpenBSD features such as the PF packet filter, network VLANs and trunks, packaged software, building your own releases, diskless installs, and more, more, more.

      Absolute OpenBSD goes into depth on the features that set OpenBSD apart from the crowd of free UNIX-like operating systems. It reaches beyond explaining what to type, and instead takes the reader into why things work that way.

      This is an excellent book for users and system administrators who want to migrate to the OpenBSD operating system.” ACM Computing Reviews

      “[This] is a well-written book that hits its market squarely on target. Those new to OpenBSD will appreciate the comprehensive approach that takes them from concept to functional execution. Existing and advanced users will benefit from the discussion of OpenBSD- specific topics such as the security features and pf administration.” –Slashdot
