More complex networking services in Red Hat Linux require more advanced administration methods. While graphical tools such as Network Configuration (via the redhat-config-network command) are available to assist in configuring all aspects of Linux networking, the best way to learn networking is by practicing with the key command line utilities and associated configuration files. | RHCE RED HAT CERTIFIED ENGINEER 9 Network Management CERTIFICATION OBJECTIVES 9.01 9.02 9.03 9.04 9.05 9.06 Q A DNS BIND Squid Proxy Server Network File System NFS Internet Network News Daemon DHCP Keeping Servers in Sync Two-Minute Drill Self Test 526 Chapter 9 Network Management More complex networking services in Red Hat Linux require more advanced administration methods. While graphical tools such as Network Configuration via the redhat-config-network command are available to assist in configuring all aspects of Linux networking the best way to learn networking is by practicing with the key command line utilities and associated configuration files. This chapter starts with a discussion of the Domain Name System DNS . DNS is a service that translates human-readable domain names such as www.mommabears.com to IP addresses such as 199.93.70.2 and vice versa. It continues by describing the basic configuration requirements of the Squid proxy server which can improve the effective response time between a user and the Internet while reducing the load on the network. Next this chapter continues with the Network File System NFS which is a powerful and versatile way of sharing filesystems between servers and workstations. The section on Internet News outlines the old familiar Usenet system and how to run a server on your network for local users. DHCP allows a Linux server to serve out dynamic IP addresses. Finally the PPP section demonstrates how a Linux server can use a dial-up connection for individual or network Internet access. As you learn about these network services you re learning about the services that you might configure and or troubleshoot on the RHCE exam. Take the time you need to understand the configuration files associated with each of these services and practice making them work on your Linux computer. In some cases two computers running Linux will be useful to practice what you learn in this chapter. CERTIFICATION OBJECTIVE 9.01 DNS BIND DNS is the .
