Basic Network Services: xinetd, NTP, DNS, DHCP, and LDAP
SUSE Linux Enterprise Server (SLES) can be used very effectively to provide different services on the network. In this chapter, you’ll learn how to work with such elementary services as NTP, DNS, DHCP, and LDAP. You’ll also learn how to set up different network services. We’ll begin with the xinetd service, also known as the Internet super service. This service can be used to listen on different ports and to start the related service as a request comes in on its port. Next, you’ll learn how to set up your server to synchronize time on the Internet. Following that, you’ll learn how to set up a DNS server, as well as a DHCP server, for automatic provision of IP-related settings to nodes. In the last section of this chapter, you’ll learn how to use LDAP as a centralized authentication service.
