In the license server, you will find license.dat file in $MATLAB_INSTALL\etc folder.
For new MATLAB client installation, pass the license.dat file to the client PC and specify this license file in MATLAB installation GUI. After installation is completed, MATLAB client automatically will point to the licence server.
For existing MATLAB client, end users need to place network.lic file in $MATLAB_INSTALL\licenses folder.
The network.lic has a format like this.
SERVER LICENSESERVERHOSTNAME HOSTID 27000
where LICENSESERVERHOSTNAME is a hostname or IP address of the license server and HOSTID is a host ID (for example, mac address) of the server. You can find the actual SERVER line information in the first line of license.dat.
If end users need to deactivate MATLAB individual license, the following steps are also needed.
