Choosing a Unix System Administration Textbook? 57

Smantha writes "I recently began teaching a Unix System Administration course at a community college. The previous instructor was using a very outdated textbook, and I'm trying to find one that is a bit more advanced and useful for my students. They are required to take a 100-level Unix class before this one and are familiar with the basics of using the command line. I'm looking for something that covers topics such as OS installation, software/package installation, user management, system administration tools, troubleshooting techniques and tools, service configuration (network services, for example) and some miscellaneous topics such as compression/archive tools, grep, make, and the like. What books have you found to be good references on your desk? What books have been good for learning these sorts of topics?"

    Define "too old".

    For an entry level class, you need to start with the classic: UNIX System Administration Handbook (3rd Edition, 2000) by Evi Nemeth, et al. If you want to focus on linux, you can go with Linux Administration Handbook (2nd Edition, 2006) by the same authors.

    Once you learn the basics, you need to pick a flavor and dive in with more "up to date" stuff. Something that covers zones, smf and zfs for solaris folks. I'm sure there are new features to linux, but I cant think of any at the OS level that dont vary widely by distro :-) (dont get me started, my biggest annoyance with "linux" is that everybody follows their own "standard" for how to configure the system.)

    Unix is 30+ years old and the basics still have not changed in a very, very long time. Its like complaining that a programing class is still using a 10+ year old book to explain looping and variable scoping.

      I think that's the best book out there. Just make sure you get the most recent edition. I had the 1st or second edition, which covered pre-Solaris SunOS, BSD 4.x on a Vax, and System V on an AT&T 3B-whatever. Their more recent editions include Linux, Solaris, and probably others (FreeBSD? AIX?).

        I learned from the second edition (red cover) circa 1995 for SunOS and Solaris, on the advice (and tutoring) of the two senior sysadmins at my work.

        I'm currently teaching my neighbor FreeBSD using the third edition (purple cover).

        The latest version still covers UNIX in a generic sense, with specifics needed for Solaris, HPUX, Linux and FreeBSD.
    • You are in the right ballpark of thought.. A good way for apprehending the bug UNIX is by focusing on POSIX. It is the standard by which some of the most modern systems (except MSFT... they wont conform) are compared to. Plus since posix is huge.. there is a lot to learn.
    • Agree with the Nemeth book, never leave home without it. Supplement this with a spare PC and a few cheap disks / other peripherals, then pick a number of Unix versions you can get for free then spend a bit of time doing all the commercial hosting oriented stuff to it. Build it, tear it down, play with disks, backups, scripts for all sorts of maint, build Apache and other standards, drag it, drop it, treat it like an object... basically use the bejeezus out of until you learn all the little twinks the book

    First off, you can't go wrong with Essential System Administration [oreilly.com], 3rd Edition by Aeleen Frisch. Really, really excellent book.

    But just as important as the specifics of Unix, I'd argue, is the general question of how to be a good sysadmin. ("Start by installing Linux" is my usual smart-ass answer, but I'll skip that for right now...) The Practice of System and Network Administration, 2nd Edition [amazon.com], by Tom Limoncelli, Christine Hogan and Strata Chalup, is a truly excellent book about how to be a good sysadmin in the general case. I can't recommend it enough. (BTW, the link for the book comes from the authors' website [everythingsysadmin.com], so I presume it throws them a few nickels if you buy it that way.)

    • by danpat (119101)
      I'll second the recommendation of "The Practice of System and Network Administration". It outlines not only what you should do, but why, and with plenty of examples of what can go wrong or right. Combine it with your own exercises to implement the specific practices it lays out and you'll be well on your way to producing some fine sysadmins, IMO.

    Also, you really should not expect there to be one great textbook for such a broad topic. Things like HTTP-server configuration, DNS configuration, POP/SMTP server admin, Security, shell scripting etc. are all separate focal points of system administration that each command entire multiple books and can each easily cover a whole semester on their own.

    The best route for teaching an entry-level class is probably to teach your students a popular shell such as Bash with a book like Learning the bash Shell, Third Edition [O'reilly publishing]. Shell interaction is really the most important fundamental skill for a UNIX systems administrator. (i.e., a sysadmin will have to be proficient with the Shell before he or she can do other critical things like securing the system, network configuration or installing software).

    It seems like you have an idea of what you want this class to be. The idea isn't to just pick a text because it's "good". It's to pick a book that has the same ideas you want to teach. You may find a "good" textbook, and just don't believe in certain philosophies in the book. You don't want to keep having to go "well, it's like this in the book, but it's better to do it my way". If you've fleshed out your ideas into actual lesson plans, it may just be better to bypass a book, and strictly go on course notes. Like I said, the main factor in this will be finding a book that melds with what you want to do.

    Books people have mentioned, such as the ORA books, ARE good references. But they aren't text books, and it probably isn't a good idea to use them like one.

    My suggestion, would be to read though some of the options here. However, if none match with what you planned, good course notes and classroom time would be the better idea. Especially if there are ideas that a book present that go against what you are teaching. You don't want students that have two conflicting ideas about a topic.

      That instructor was not only good, he was more honest than most people would have been in his position. The normal response to that situation is to write your own text book, require that all your students use it and come out with new editions regularly with only minor changes to keep them from buying used copies. Many professors have financed their retirements by doing exactly that.

    Okay, so you want to teach people Unix.

    First off, it's important that you know unix yourself. Then it is important to explain the unix philosophy, and start with the basics. Since I do a bit of unix teaching, I think I'll put forward how I prefer to teach my pupils.

    First off, it's important that they know the basic philosophy.
      - Everything is a file
      - Many small utilities, that does its own little thing
      - Utilities can be combined.

    Choose a decent shell, and teach them how to use it. bash seems to be the industry standard, so go for that (or go for whatever you want, but be certain that you know it yourself).

    Then teach them about STDIN, STDOUT and STDERR.

    Explain that each utility they launch have those three file descriptors. Teach them pipes. Explain that pipes connects STDOUT from one process to STDIN of another. Explain that you can redirect STDERR to STDOUT to include it in the pipe. Explain that you can connect STDOUT to a file. Explain that you can connect a file to STDIN.

    Explain command line substitution (backticks).

    Then go forth and explain the basic utilities. Explain how to use 'man' and 'apropos' (or man -k). Explain the other basics such as cat, grep, cut, tr, find, xargs, df, kill (man signal), pkill, the evils of killall, ifconfig, netstat, and so forth. Explain how you can use pipes with these utilities. When they've mastered the basic utilities, move on to explaining sed and awk.

    When they've understood these basics, which they should after some 3-4 lectures + training sessions - they can move on to the more advanced stuff.

    Explain about filesystem hiarchies. Explain the basics of filesystems and what inodes are. Explain atime, mtime, ctime. Explain how to use fdisk (or format if solaris). Explain how to create filesystems - and why inode density might be important. Explain why it's important with different partitions / disks. Then move on to explaining volume management.

    At some point, they should read "Learning the bash shell" (or a similiar book for other shells), and learn shell scripting.
    At some point, they should choose themselves another scripting language, be it perl, python, ruby or something else.

    After they are past these basics, you should start talking about actual system administration. They are now ready to move on to topics such as how to configure syslogging, NFS and how to configure the local mailer daemon. After that they should now have had to touch the MX records, and DNS might pique their interest. Teach them bind. Then teach them another DNS daemon just to show that there are more of them. djbdns might be a good alternative.

    If you're evil, this might be a good time to teach them to hate printing by trying to explain to them how to configure a print-server. Make sure there are some evil printers around. It's important to teach them about both postscript-printers and the evils of non-postscript printers.

    After all this, they should have a toolchest big enough to be able to do the rest themselves. They're ready to be self-taught for the rest of whatever they need to do.
  • Definitely take a look at the second edition of O'Reilly's LPI Linux Certification in a Nutshell. The table of contents [oreilly.com] shows great overlap with the topics you're interested in.
  • While there are plenty of books out there on Unix, not all of them cover all flavours of Unix. Sometimes you are better off getting something that covers one flavour well, or be happy with one that is a good compromise of all of them. The book I have is Essential System Administration [oreilly.com]. It is a good book, but there are are certainly times that I would like a bit more depth on certain subjects, but when that need arises I usually head off to the internet.
  • Thanks for all the advice, guys! I have tossed around the idea of going without a textbook, but, in that case, I'd at least like a good reference book so that those that don't learn well from hearing something spoken will have something written to lean on. As for the "install Linux" idea - that's day 2 of my lesson plan. I bring in a bunch of disks (various flavors of Linux) and set them loose. The comments suggesting "the basics" are correct, but as the OP notes, there is a 100-level class that they tak
