    Interested in Linux admin, wanted to self learn, please let me know
    what are important things I have to learn for Admin point of view. By
    looking at On-line postings, I came to know these are important,
    besides these what else are important to learn:

    1) Samba installation and setup
    2) Web server setup
    3) Usr account creation

    Besides those three, is there any things are important, also which
    Distribution is better for Server side as well as Client side
    (especially for small businesses point if view).

    Thanks for your time.

    Hey! that's a religious question, otherwise. The best could be same for
    which you are most comfortable; OTH, FYI, broadly speaking all the Linux
    distros can only be classified either as commercial or as community
    supported. For a production system I for one shall go in for decent and
    stable commercial distro with 24/7 customer support.

    What's most important to ''learn'' (I don't know if it can be learned)
    is how to think critically and how to read documentation. There is a
    bit of an art to both. With these two skills, you can do pretty much
    anything in the sysadmin world (not just linux, either).
    If 30 people post their answer to the above question, you'll likely get
    35 different answers. To the experienced admin they're all more similar
    than they are different.

    Add to this very good list of topics possibly before any of the others:

    -1) Security:
    -1.5 Hardening the system
    -1.6 (Stealing from above) Firewall planning/setup
    -1.7 ssh selection, installation, setup
    -1.8 change control procedures, monitoring, etc

  5. Agreed, we both missed, in important:

    0.x) Print Server (CUPS/lpRNG) software selection, installation and

    And ... a much needed now a days, an iPBX Server (Asterisk/YATE)
    software selection, installation and setup, which may further require
    text-to-speech (festival/epos/recite) software.

    Grab a good book, and work through it. O'Reilly's "Running Linux", for
    example. ISBN: 0-596-00272-6

    You might also want to pick up a "cheat sheet" book, like O'Reilly's
    "Linux in a Nutshell" ... I'll let you look up that one, if you're

    That's how I got started, anyway. Well, that, and the somewhat
    frequent pestering of the friend who got me involved with Linux.
    (Haven't seen him IRL in a while, come to think of it.)

  7. It's all important.

    What is administration, anyway? It's making the machine do whatever it
    is its owners need it to do. You may not need to know the details of
    applications (though that may not be the case always) but you certainly
    have to know how the apps being used affect the OS and the hardware and
    vice-versa. An administrator may not be a "performance expert" or a
    "storage expert" or an "* expert", but you do need familiarity with all
    those things. And because Windows boxen will undoubtedly be in the mix,
    you need at least some knowledge of that crapola also (pardon my
    prejudice - does it show?).

    An administrator, then, is a generalist. Unless you know ahead of time
    that you will be working for XYZ and their environment consists of a, b
    and d, you can't afford to spend too much time learning too many
    details. I don't mean to imply that superficiality is your goal, but
    you have to balance depth against breadth and realize that
    administrators usually need breadth more than depth. It's a tough act
    sometimes - I know I constantly find myself learning more than I really
    wanted to know about Y and wishing I had the time to really dig into Z.

    One thing you might find useful is my Linux Skills Tests at
    http://aplawrence.com/Tests/Linux . I originally developed these for
    testing tech job applicants - I'd sit down with the person and have them
    verbally answer a few dozen questions like this.. it gave me a real good
    idea of how broad their skills were (tech folk need perhaps even broader
    skills than admins).. anyway, it might help show you where your weak
    areas are. Some of the questions are very basic, some aren't, but if
    you find yourself really thrown by a lot of them, you need a lot of
    work. Most of the people who answer questions here would likely waltz
    through them and quit out of boredom rather soon - if that's your
    experience, you are probably well prepared to be an admin. And if not..
    well, learning just takes time and effort, right?

    Mike and other guys:

    Thanks for your time for giving valuable info. I ordered those books,
    Please let me know if there is any other books for Linux Admin, I heard
    from a friend that there are some books are available on INternet also,
    can I use those book?.

    One more question is, I need to download Fedora (client) and latest RH
    version (server side), will those two versions serve my purpose for
    Server and Client purpose, I wanted to download Debian and Suse also,
    please give me your valuable idea.

    Thanks and appreciated for your time.

  9. Get yourself "cheat sheets" or "quick references" for the various
    packages. A good understanding of scripting languages will also take you
    a long way, if you're to automate things - study up Bash syntax, as well
    as something like perl.

    Can somebody suggest me, which version I have to use for Server and
    which version for client in freely available distributions. Thanks in

    Dr. Balwinder,

    Appreciated for your response, You mentioned many severs installation
    and setup, If I take any one of the Distribution for example RH, all
    those servers are part of the package, Or do I have to separately
    download and install it. I believe all those are part of the package. I
    tried to install the RH, it gave me soma options like 1) Server 2)
    Desktop 3) Workstation 4) customized, if I select Server for Server, it
    should install all the server packages, similarly for client machines,
    If I select client, then it should install the necessary client
    packages, mainly I have to setup based on whether it is for client or
    server, I am reading Linux is very popular on Servers side only, but on
    client side still many corporate offices are using Windows desktops I
    believe. Please correct me if I am wrong here.

    Thanks again,GS.

  12. Well, you are right, but there is some movement back to terminals on the
    desktop - not old green screen terminals, but GUI based RDP, X or
    whatever. If you have no idea what I'm talking about, see

    The advantages to business are return of more control to the MIS
    department, easier deployment of upgrades, less concern about viruses,
    spyware, etc (or at least less kittens to chase). These terminals can
    also be less expensive, more reliable, and easier to "repair" (just
    replace it). Many of these, particularly at the low end of the market,
    run Linux as the underlying OS.

    So, yes, right now Windows desktops are the most common circumstance,
    but MIS departments expend tremendous energy and money because of that,
    so the tide may be shifting. The ability to do this has been available
    for quite a few years (I was doing Citrix stuff longer ago than I care
    to remember, and X terminals before that), but it's much more palatable
    then it was a decade ago. That's partially because the technology has
    gotten better, particularly for remote office use, partially because
    Windows apps now play much better in a multiuser environment than they
    did previously, but I think mostly it is driven by the frustration with
    viri, spyware and the many inscrutable and time consuming glitches that
    plague Windows desktops.

    The beautiful thing about it from a Redmond hater's point of view is
    that the client/server model makes it much easier for an app vendor to
    return to or switch to Unix/Linux and much more likely that they will
    contemplate doing so. We may yet see the day when people say "Gawd..
    remember when we had all that awful Microsoft crap in here?"

    Most distributions can be configured to perform either task. Any of
    the major ones can, and most of the minor ones.

    "Running Linux" will have you working with a specific distribution,
    though I'm not sure which. Start with that one; Most of the skills
    should carry over to any distribution you choose. That's the beauty of
    Linux. Not only is the software largely interchangable, the skills
    carry, too.
