Chapter 19. Networking Fundamentals (Topic 1.12)

While it is not necessary for you to be a networking expert to pass the LPIC Level 1 exams, you must be familiar with networking, network-related vocabulary, and Linux networking configuration. This section introduces fundamental networking, troubleshooting, and dialup concepts specifically included in the exams. However, it is not a complete introductory treatment, and you are encouraged to review additional material for more depth. This section covers these three Objectives:

Objective 1: Fundamentals of TCP/IP

This Objective includes TCP/IP basics such as network masks, ports, and utility programs. Weight: 4.

Objective 2: (Superseded by LPI.)

An Objective 2 was originally included by the LPI in this Topic, but was later superseded by other Objectives. It remains in place to keep Objective numbering historically consistent and is likewise included here.

Objective 3: TCP/IP Troubleshooting and Configuration

This Objective describes how to configure Linux network interfaces, including DHCP. Weight: 10.

Objective 4: Configure and Use PPP.

This Objective includes the description of PPP client and server configuration. Weight: 4.

What follows is not a complete treatment of TCP/IP, but rather a refresher of its core concepts as they apply to Exam 102.
