In a TCP/IP environment, working with services happens in a static way most of the time. For example, the DNS server provides information about what IP address must be contacted as the mail server for a given domain, but it doesn't give any guarantees that this mail server is actually available when you try to contact it. A much better method to provide information about available services is to use a dynamic method. The Service Location Protocol (SLP) is an RFC standard that provides such a method. SUSE Linux Enterprise Server comes with OpenSLP, the open source implementation of that protocol. In this chapter, you'll learn how to use and configure it.
