LPI Linux Certification in a Nutshell, 2nd Edition

Chapter 19. Networking Fundamentals (Topic 1.112)

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 basic Linux networking configuration. This chapter introduces fundamental networking, troubleshooting, and dial-up 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 chapter covers these three Objectives:

Objective 1: Fundamentals of TCP/IP

Candidates should demonstrate a proper understanding of network fundamentals. This Objective includes the understanding of IP addresses, network masks, and what they mean (i.e., determine a network and broadcast address for a host based on its subnet mask in dotted quad or abbreviated notation or determine the network address, broadcast address, and netmask when given an IP address and number of bits). It also covers the understanding of the network classes and classless subnets (CIDR) and the reserved addresses for private network use. It includes the understanding of the function and application of a default route. It also includes the understanding of basic Internet protocols (IP, ICMP, TCP, UDP) and the more common TCP and UDP ports (20, 21, 23, 25, 53, 80, 110, 119, 139, 143, 161). Weight: 4.

Objective 3: TCP/IP Configuration and Troubleshooting

Candidates should be able to view, change, and verify configuration ...
