Matlab installation error on Ubuntu 11.04

Asked By 20 points N/A Posted on -

Hi all,

I am using Ubuntu 11.04 and have installed Matlab on it. After the installation process I faced an error when wants to run it:

License checkout failed.
License Manager Error -15
MATLAB is unable to connect to the license server.
Check that the license manager has been started, and that the MATLAB client machine can communicate
with the license server.
Troubleshoot this issue by visiting:
ww.mathworks.com/support/lme/R2011a/15
Diagnostic Information:
Feature: MATLAB
License path: /root/.matlab/R2011a_licenses:/usr/local/MATLAB/R2011a/licenses/license.dat:/usr/local/MATLAB/R2011a
/licenses/network.lic

FLEXnet Licensing error: -15,570. System Error: 115

I tried looking for solutions about this on various forums, but I'm unable to understand because I’m a new user of Linux. I got a suggested solution in this link: http://ubuntuforums.org/showthread.php?t=689618

I am aware of my hostname but I don’t understand what is needed to compare to it. Need help please.

Thanks a lot.

Dear Phillipus,

The link you provided is with an error message number different from the one you got. The error message 15 indicates that the license manager is not running or that your machine couldn't communicate with the server machine which runs the license manager.

Try to ping the license manager machine using the command "ping <server machine hostname>" in a terminal. If you received an error, then you have a networking issue that prevents from contacting the license manager server.

Also make sure that the SERVER line in the license.dat file on both the client and server are the same. Again, a firewall between the client and server may cause this problem.

Hope this may help you.

Best of luck.

License Manager Error – 15 can have various reasons but the most common is that your license manager is not running on your license server or it may be the client machine that could not establish a connection with the server machine that runs the license manager. To fix this, check if the lmgrd and mlm are both running. You can be able to check on this through Task Manager on which you can access by pressing the Ctrl+Alt+Delete key.

If you are getting this error on a MATLAB client installation, verify the following:

1. Check if the client computer can communicate with the license manager server. Try to ping the license manager machine by running "ping <hostname>" on the command prompt.

2. Ensure that the license .dat SERVER line matches the license file on the server.

3. Check the Firewall settings on MATLAB client and the license server machine.

If you are getting this error on the installation of the license manager, verify the following:

1. Check the FLEXnet service if it is running on the license manager server. If it's not then restart your license manager and then run the MATLAB again.

2. Ensure that the TCP port numbers on your server or DAEMON lines under the license .dat is are not being used by another application.
