Chapter 8. Network Services

One major strength of Linux is in its offering of a wide range of network services. SLES 9 ships with a large number of such services, ranging from network time services to file sharing to web page serving. A detailed discussion of each topic discussed in this chapter is not feasible due to space; entire books are devoted to many of the topics, such as the Domain Name Service (DNS) and Samba. Therefore, the intention of this chapter is to provide you with the bare necessities to get a specific network service configured and running with a basic configuration.

We selected the topics covered here because they provide services to users on your local, private network, and not necessarily services over the Internet. This is why certain topics, such as the Squid proxy server and SuSEfirewall2, are not discussed here. The following topics, however, are discussed in this chapter:

• The xinetd super-server

• The Network Time Protocol (NTP) service

• Email services using Postfix

• FTP servers

• File sharing using NFS and Samba

• Remote management using VNC, XDMCP, and Telnet/ssh

• Network name services using DNS, DHCP, SLP, and Samba

• Web page serving using Apache

• Authentication services using Kerberos, LDAP, NIS, and Samba

There are other services beyond those available with SLES. Novell's Open Enterprise Server (www.novell.com/products/openenterpriseserver/) provides a number of extra services (such as NetStorage and iFolder) that help bring the Novell and SLES world closer. These extra services are, however, beyond the scope of this chapter.
