Book: LPI Linux Certification in a Nutshell Section: Part II: General Linux Exam 102
## Chapter 20. Networking Services (Topic 1.13) Much of the success of Linux can be attributed to bundled networking services, such as the Apache web server, sendmail, NFS and Windows file sharing, and others. This section covers these five Objectives on networking services: Objective 1: Configure and Manage inetd and Related Services This Objective includes the so-called Internet superdaemon, or inetd . This single daemon manages other service-specific daemons, dispatching them as needed in response to inbound requests. Also included is the TCP wrappers facility for adding access control to inetd. Weight: 5. Objective 2: Operate and Perform Basic Configuration of sendmail sendmail is probably the most common mail transfer agent on the Internet. This Objective covers only the basics of sendmail configuration, including its alias feature. Weight: 5. Objective 3: Operate and Perform Basic Configuration of Apache Apache is the most popular HTTP server on the Internet and is the default web server for most Linux distributions. This Objective covers basic configuration of Apache. Weight: 3. Objective 4: Properly Manage the NFS, smb, and nmb Daemons This Objective covers file sharing using both NFS (Unix) and SMB (Samba, the open source file server for integrating Linux within a Windows network). Weight: 4. Objective 5: Set Up and Configure Basic DNS Services This Objective covers the basic configuration of DNS and address resolution settings. Weight: 3. For systems deployed as servers, even in a small department, these Objectives cover some of most important system administration concepts to be performed for Linux.
