Install a free Unix-like operating system on your computer and play with
More verbosely: install some version of Linux. I would suggest one of the
less "newbie friendly" distributions, such as Debian or Slackware. Or you
might want to go with OpenBSD, FreeBSD or NetBSD (which are like Linux in
that they are free Unix-like OSes, but they are from a different "school"
of Unix, but still equally useful for learning Unix administration).
I would recommend getting an old PC to try this on. You should be able to
pick up a 486 or early Pentium for not much money. This hardware will be
fine for playing with Linux and learning about it.
Once you get the system installed, start making the computer useful. The
following are some typical tasks that a Unix admin should probably know
how to do:
- set up X
- configure and use network devices: ethernet, serial analog modem,
- install and use a printer
- download a program's source code, compile it, and install it on your
system (i.e., do *not* use the system's package management tool to
- configure system services, especially common ones such as:
- FTP (e.g. proftpd)
- a web server (e.g. Apache)
- a mailer (e.g. postfix, or sendmail if you're brave)
- secure shell (e.g. OpenSSH)
- familiarize yourself with shell scripts (and maybe perl
scripts)---at *least* enough that you can understand what's going on
in them (and that's a bare minimum)
- configure and recompile your kernel
Keep in mind, that once you do these things in Linux, it doesn't mean you
can do it immediately on any flavor of Unix (because they all have varying
degrees of difference). But you will develop a "Unix intution"; i.e.,
you'll understand the rationale behind the design of a Unix system.
Keep in mind, when doing any of the tasks listed above, do *not* use any
kind of auto configuration tool, such a Linuxconf. If you do, it's
cheating, and you won't really learn anything about what's going on in
Once you can do the things I listed above, you should be comfortable
enough with a Unix-like operating system that you can come up with your
own admin tasks, such as setting up a LAN (with Linux *and* Unix clients),
setting up a firewall, perhaps running a small dial-in ISP, etc.

Everyone seems to have their own thoughts on this, all are valid. My idea
is for you to download the source code to a program that you like, but
lacks the features that you want. Read through the code to figure out how
the original program works, then try to add your desired functionality.
A major drawback to this approach, however, is that you might pick up some
sloppy coding practices from the original programmer :) But there's
plenty of well-written open source software, though.

In my opinion, Debian is a good choice of distro for a newbie who wants to
be a Unix admin.
