Red Hat Linux can act as any of (Anonymous web server)
Red Hat Linux can act as any of the server types described above. However, with a growing number of productivity applications becoming available for Linux and friendly X-based desktops (such as KDE and GNOME), Red Hat Linux is beginning to make a better case for becoming a client system as well. Because Red Hat Linux can run applications as well as offer services, a purer example of a network server is NetWare (from Novell, Inc.). A NetWare server has no way of running applications. It is tuned to store and secure files efficiently, as well as manage groups of printers. With the addition of ZENworks and NDS, NetWare can manage databases of information on all the components on a network. Cross-Reference Chapters 17 through 23 describe how to set up different kinds of servers in Red Hat Linux. Peer-to-peer model In a peer-to-peer network, computers generally behave as equals. Each computer has most of what it needs to operate on its own. Any computer on the network may offer services to other computers. One computer may share the contents of a CD-ROM, whereas another may offer its printer for use by others. A typical peer-to-peer network is one where several employees in a business each have a computer at their desk. A shared printer may be connected to one person s computer, whereas a tape backup system may be connected to another. The drawback with peer-to-peer networks is that if there is a big demand for your printer or other device, your computer s performance may suffer (and so may your work). That s why larger networks tend to offload shared services to a server. After you have made a choice about the typology and computing model you are going to use, the following sections tell you how to actually configure your computers so that they can communicate together. Setting Up an Ethernet LAN After you physically install your Ethernet card, it is possible that Red Hat Linux will automatically detect your card and assign it to the first Ethernet interface on your system (eth0). If Red Hat Linux does find your card, after you connect your hardware you don’t need to do much more than assign addresses. Follow this procedure to set up your LAN and install your LAN cards: 1. Choose a network topology. Earlier in this chapter, I described several different network topologies. This procedure assumes that you are using either a star or a bus Ethernet topology. 2. Choose your LAN hardware. You need an Ethernet NIC for each computer on your network, as well as cables that reach from each computer to the hub. Also, you need to purchase a hub. (See the description of these components earlier in this chapter.) Before you purchase a new NIC, read the following discussion on choosing an Ethernet card. Red Hat Linux does not support all NICs. Choosing one that has already been tested with Red Hat Linux can save you some headaches. 3. Install your NIC cards. Power down your computer and physically install the NIC card (following the manufacturer s instructions). 4.
