About this series

The Linux Professional Institute (LPI) certifies Linux system administrators at three levels: junior level (also called "certification level 1"), advanced level (also called "certification level 2"), and senior level (also called "certification level 3"). To attain certification level 1, you must pass exams 101 and 102. To attain certification level 2, you must pass exams 201 and 202. To attain certification level 3, you must have an active advanced-level certification and pass exam 301 ("core"). You may also pass additional specialty exams at the senior level.

developerWorks offers tutorials to help you prepare for the five junior, advanced, and senior certification exams. Each exam covers several topics, and each topic has a corresponding self-study tutorial on developerWorks. Table 1 lists the six topics and corresponding developerWorks tutorials for LPI exam 301.

Prerequisites

To get the most from this tutorial, you should have advanced knowledge of Linux and a working Linux system on which to practice the commands covered.

If your fundamental Linux skills are a bit rusty, you may want to first review the tutorials for the LPIC-1 and LPIC-2 exams.

Different versions of a program may format output differently, so your results may not look exactly like the listings and figures in this tutorial.


System requirements

To follow along with the examples in these tutorials, you'll need a Linux workstation with the OpenLDAP package and support for PAM. Most modern distributions meet these requirements.
