Well, in my opinion a sysadmin does not need to be a master of every single piece of technology but he(she) must understand the concept and have a vision of the whole.

- OS (Unix, Windows)
- Security
- Hardware
- Networking
- Webserver / Email server
- Application Server
- Programming (but scripts is a must for *nix world)
- Databases

And must important, patience and will to learn always helps !

    Linux is often used for infrastructure services such as web,

    MySQL and Bind is a minimum these days. Being able to script is
    essential too. Shell, Python, Perl are the popular ones. I
    personally prefer Python these days.

    You also need to have some networking knowledge. I'm not talking
    about configuring BGP here, but you gotta be able to configure
    switches, routers, probably load-balancers. Understanding routing
    is essential to improve your debugging.

    Virtualization is another sphere in high demand. VMware, XEN and
    OpenVZ are popular.

    To become a sysadmin, you need to put in the hours. You gotta be
    ready to keep learning during your entire career. Until you get a
    job that allows you to better your skills during workhours, you
    will have to do that at home.

        Not to sound pessimistic but this is not the impression that I
        got. I've
        been looking for a job for the last 6 months and I don't see a
        lot of
        offers. Add to that the fact that everyone seems to ask for 5+
        years of
        experience...in everything. Even in technologies such as Adobe
        Flex
        (which came out in march 2004)

        As a general advice, I would says that Red Hat seems to be the
        distribution of choise, with Suse a distant second. Database
        skills are
        also a plus (something I don't have and get turned down
        becasue of it).
        And remember that to get the job, you don't need to be a good
        candidate,
        you need to be the best one among the ones they interviewed.

        Of course, knowing the right people also helps. I don't have
        connections, and my only real source of job offers are the
        billboards.

        Good luck!
