FLEXlmTM provides a wide number of tools for the license managing, all of them are well described in the FLEXlm End User Guide. To start the license manager on a UNIX box the lmgrd command has to be used. The simplest way to start the daemon is to use the command:
FLEXlm_path/lmgrd -c license_path/license.dat
where FLEXlm_path is the absolute path where the FLEXlmTM tools are saved (usually .../ESTECO/modeFRONTIER3xx/lic) and license_path is the absolute path where the license.dat file was saved.
If you want to start the license daemon at startup each UNIX System has some strange system dependent way to do it. We can just show a simple example how to solve this problem.
Let's write a shell script which execute the lmgrd command:
#!/bin/sh nohup /bin/su frontier -c 'echo "exec FLEXlm command: lmgrd" > log_path/license.log' nohup /bin/su frontier -c 'FLEXlm_path/lmgrd -c license_path/license.dat >> log_path/license.log' sleep 3 nohup /bin/su frontier -c 'echo "exec FLEXlm command: lmdiag" >> log_path/license.log' nohup /bin/su frontier -c 'FLEXlm_path/lmdiag -n -c license_path/license.dat >> log_path/license.log' exit 0
Since this script has to be run at boot only absolute paths must be used. The vendor daemon esteco has to be in the same directory of lmgrd or his path must be defined on the SERVER|VENDOR line in the license.dat file.
DAEMON esteco mypath/esteco
For security reasons it is always recommended to run the lmgrd daemon under a user different than root. In this case the /bin/su command will run the service under the frontier user.
Save the script in a file called flexlm_daemon and ask the system administrator to modify the necessary boot files to start the FLEXlmTM license daemon when your server boots.
Since the UNIX machines can be quite different and user dependent some hints on how to set up the boot files can be shown for the following architectures:
Copy flexlm_daemon to /etc/rc.d/init.d.
Modify its permissions to be the same as the owner of the directory (e.g. root).
List the content of /etc/rc.d/rc3.d (run level 3) and pick a number which is not in use and is not smaller then the one for xinetd, let's say 70.
ls /etc/rc.d/rc3.d

S13portmap S20random S28autofs S55sshd S60lpd S90crond S95rcsge
Create a symbolic link from /etc/rc.d/rc3.d to the flexlm_daemon script in /etc/rc.d/init.d.
cd /etc/rc.d/rc3.d
ln -s ../init.d/flexlm_daemon S70flexlm
Similarly list the content of /etc/rc.d/rc5.d (run level 5) and pick a number which is not in use and is not smaller then the one for xinetd, let's say 70.
Create another symbolic link from /etc/rc.d/rc5.d to the flexlm_daemon script in /etc/rc.d/init.d.
Reboot the system to start the license manager.
Copy flexlm_daemon to /sbin/init.d.
Modify its permissions to be the same as the owner of the directory.
List the content of /sbin/rc2.d and pick a number which is not in use, let's say 780.
