All Manuals > LispWorks Guide to the License Server > 2 The License Server Daemon


2.1 Overview

The License Server daemon, hqn_lsd, provides secure network licensing services for Lisp. Together with its administration utility, hqn_lsa, it allows flexible but simple centralized control over the use of licensed applications throughout a network.

The daemon itself is licensed to run on one or more specific host machines at any given site. Where multiple hosts are specified this constitutes a server domain . Any host within a server domain can be configured as the active license server, while the rest provide backup services in case of failure of the current server.

Product licenses are provided in human-readable permit files.

Product licenses are locked to a particular server domain, that is, only daemons within that domain will serve licenses for the product (the product itself can of course be run anywhere within the network depending on its policy configuration).
