Service for controlling commercial software distribution.

License Manager


The license manager controls commercial software such as the MIPSpro compilers and Maya.

The license manager gets hash of the primary MAC address and compares it with a license file.

The license manager can be on another computer and runs as a service on a port to check out and check in licenses.



returns the host license ID, the ethernet MAC address or for newer machines a hash of it. Multiple module systems may change lmhostids when adding or removing modules.





If the software which requires license crashes (most likely with Bus Error or Segmentation Fault), it's possible it's because of licensing issues. Please make sure that you only have one single master file with all the licenses under /var/flexlm/ - if you have more than one some applications get confused and crash.

If this doesn't help, try to investigate system calls being executed just before the crash with strace or par, you may at least be able to narrow down your search.


If you've installed a license and tried to run the protected software, you may see an error message such as Unable to find a license or Unable to find a license server. Use the methods described in this section to check the installation.

Run the Unix command /usr/sbin/lmdiag. This command analyzes the licenses in the default licens file (/var/flexlm/license.dat), which may help debug problems. If you get an error message that says the HOSTID is incorrect, check the HOSTID:

If the license you are having problems with is a Nodelocked license, in a Unix shell run the command /etc/sysinfo -s. If the result does not match the HOSTID string for that product in the license file, this is the problem.

If the license you are having problems with is a Floating license, on the server system, run the Unix command /etc/sysinfo -s. Compare the results with the second argument on the SERVER line, which corresponds to the product in question. If the two numbers are not identical, this is the problem.

A few conditions might cause the /etc/sysinfo -s results and the HOSTID to be different:
The license may be made for a system different from the one you are running it on.
The HOSTID may have been entered incorrectly.
The HOSTID on the system may have changed. If the CPU board or I/O board was replaced, this can change the HOSTID.

If you are having trouble with a FLEXlm Floating license, try the following procedure:

You may wish to configure the lmgrd daemon to send its output to a log file rather than sending it to standard output. To do this, edit the file /etc/config/lmgrd.options and add a line that looks like:

-c /var/flexlm/license_<server_name>.dat -l /var/adm/flexlm.log

Where the file after the -l is the log file. Note that -l is a lowercase L, not a number 1 (one).

In a Unix shell, type:
/etc/init.d/flexlm stop; /etc/init.d/flexlm start 

Look at the log file for error messages.

If the lmgrd daemon is started (check the log file), on the client system, run the Unix command:
/usr/sbin/lmstat -a.

This tells you whether the lmstat tool has the same trouble contacting the server as the client application.

If the application program on the client system cannot connect to the server to check out a license, one of several things may be wrong:

The license server may be down, or there may be a network problem. Check to see if the client system can communicate with the server. In a Unix shell on the server, enter:

/usr/bin/lmstat -a

To verify the vendor daemon is running. In a Unix shell on the client system, enter:

lmstat -a

To check if it can contact the vendor daemon on the server. Then, from the client system, enter the command:


Where hostname and portnumber match the SERVER line in the license file.

The vendor daemon may not be running. On the server, check for the Silicon Graphics vendor daemon by running the Unix command:

ps -ef | grep sgifd | grep -v grep

If nothing is returned, then the vendor daemon is not running.

The application may not be looking at the expected license file. The default license file is /var/flexlm/license.dat. By default, Silicon Graphics applications that are licensed with FLEXlm use this file.

If a warning message appears stating that the license expires in an incorrect number of days, see "Installing a Nodelocked License" in this document. Follow the steps to remove or comment out any existing temporary or evaluation license(s) in the /var/flexlm/license.dat file for this product.

The License Password may have been typed incorrectly. Check that the letters l and O were not typed in place of a numberal 1 (one) or 0 (zero).

The license you are entering may not be the correct type. Check the License Type on the license information sheet. If you are following the instructions for installing a nodelocked license, be sure that it says "Nodelocked". See "Installing a Nodelocked License" in this document.

The system time may be set incorrectly or the license may have expired. Run the date command by typing date. Make sure the date is not earlier than the Start Date or later than the Expiration Date listed on the license information sheet.

For more information on troubleshooting, refer to Appendix B of the FLEXlm End User Manual. This guide is located in the IRIS InSight Library, which you can find by selecting "Online Books" from the Help toolchest.
