The information on this page refers to v4.4.3 and later, which introduced an installation program that installs both LM-X License Server and the end-user tools and removed some commands from lmx-serv. For applicable to earlier versions, see documentation for previous versions.

The lmx-serv command will let you run the license server as a service in Windows or as a daemon in the background on Unix. However, it is recommended that you use the provided installer to install and start the license server instead of using lmx-serv.

The lmx-serv command usage is as follows.

For Windows:




[-config configfile -licpath licensefile -logfile logfile -port portnumber]

For Unix:




[-background -config configfile -licpath licensefile -logfile logfile -port portnumber]

Applies to





Run the license server as a daemon in the background.




Specify an optional path to an lmx-serv.cfg configuration file. Typing the full path is required. If the server is run without the -c parameter, it will use default settings.




Specify an optional license file path that will be read in addition to those specified within the lmx-serv.cfg configuration file.
Alternatively, you may specify a directory in which the license server will look for all .lic files. You can specify multiple paths, separated by a semicolon ( ; ) for Windows or a colon ( : ) for Unix; for example, "-l C:\dir1;c:\dir2."

If no default license is defined in the configuration file and the -l parameter is not specified (or no license can be found in given location), the server will look for all .lic files in its directory.




Specify an optional logfile path, which will override any logfile settings in the lmx-serv.cfg configuration file.




Specify an optional port number, which will override the port number set in the configuration file.




Print out usage information for these commands.

We recommend enclosing all switches (e.g., configuration file path) within double quotes (" ") to avoid problems with white spaces.
