License Management (MATLAB Installation Guide for Unix) MATLAB Installation Guide for Unix     License Manager Daemon The FLEXlm license manager daemon (lmgrd) runs as a background process on a network node. This daemon is responsible for managing the initial communication between client applications, such as MATLAB, and vendor daemons. Client applications contact the license manager daemon to request permission to run licensed software. The license manager daemon forwards the request to the vendor daemon, which grants or denies access to the software, depending on the availability of license keys. The license manager daemon is also responsible for starting and stopping the vendor daemons. By default, The MathWorks installs the license manager daemon in a subdirectory of the MATLAB installation directory, $MATLAB/etc/$ARCH where $ARCH represents an platform-specific name. For example, on a Sun system the directory name is $MATLAB/etc/sol2. This eases the installation task and prevents conflict with other applications that use FLEXlm license management. You can run several license manager daemons on the same system.  Licensing Components Vendor Daemon
