LPI exam prep: Networking configuration

Intermediate Level Administration (LPIC-2) topic 205

David Mertz (mertz@gnosis.cx), Developer, Gnosis Software

David Mertz has been writing the developerWorks columns Charming Python and XML Matters since 2000. Check out his book Text Processing in Python. For more on David, see his personal Web page.

Summary: This is the first of seven tutorials covering intermediate network administration on Linux®. In this tutorial, David Mertz shows you how to configure a basic TCP/IP network, from the hardware layer (usually Ethernet, modem, ISDN, or 802.11), through the routing of network addresses. Higher level servers that may operate on these configured networks are covered in later tutorials.

About this series

The Linux Professional Institute (LPI) certifies Linux system administrators at two levels: junior level (also called "certification level 1") and intermediate level (also called "certification level 2"). To attain certification level 1, you must pass exams 101 and 102; to attain certification level 2, you must pass exams 201 and 202.

developerWorks offers tutorials to help you prepare for each of the four exams. Each exam covers several topics, and each topic has a corresponding self-study tutorial on developerWorks. For LPI exam 202, the seven topics and corresponding developerWorks tutorials are:

*Table 1. LPI exam 202: Tutorials and topics*

About this tutorial

Welcome to "Networking configuration", the first of seven tutorials covering intermediate network administration on Linux. In this tutorial, you learn how to configure a basic TCP/IP network from the hardware layer (usually Ethernet, modem, ISDN, or 802.11) through the routing of network addresses. Higher level servers that may operate on these configured networks are covered in later tutorials.

This tutorial is organized according to the LPI objectives for this topic. Very roughly, expect more questions on the exam for objectives with higher weight.

*Table 2. Networking configuration: Exam objectives covered in this tutorial*
LPI exam objective	Objective weight	Objective summary
2.205.1 Basic networking configuration	Weight 5	Configure a network device to be able to connect to a local network and a wide-area network. This objective includes being able to communicate between various subnets within a single network, configure dialup access using mgetty, configure dialup access using a modem or ISDN, configure authentication protocols such as PAP and CHAP, and configure TCP/IP logging.
2.205.2 Advanced network configuration and troubleshooting	Weight 3	Configure a network device to implement various network authentication schemes. This objective includes configuring a multi-homed network device, configuring a virtual private network, and resolving networking and communication problems.

Prerequisites

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