-Run it from sthelens, and only if sthelens is down, from cher, orsay or tiree. It works on other machines too, but some of the other machines have older versions of the OS and core dump upon exiting from matlab. Some other local machines with new setups work fine. Try your local machine. Matlab is blocked from running on the servers (koko and okok).+cities and moods. 
 +You are not allowed to run it on vostok because of its gateway functionality.

==== What to do if Matlab won't start ==== ==== What to do if Matlab won't start ====
There can be three reasons for Matlab not to start: There can be three reasons for Matlab not to start:
-  - //You are on the wrong machine//, usually koko. See previous tip+  - //You are on the wrong machine//, like teslas
-  - //Koko has rebooted and the license manager has not been started yet because the autostart script is broken.// If you do not have koko's root password call either the Matlab Administrator or somebody with a root password. If you do have koko's root password, "su", then "su - lomask" . Type: \\ "/linux_local/matlab71/etc/lmdown -glnx86; /linux_local/matlab71/etc/lmstart -glnx86" +  - //vostok has rebooted and the license manager has not been started yet. The steps to restart license server: 1) Log onto vostok 2) cd /opt/matlab2011b/etc/ 3) run ./lmdown 4) run ./lmstart. If it does not return error msg, it indicates the license manager has been started successfully.//
-  - //More than 5 users are running Matlab//. This happens about two times a quarter. On any machine, type "ls /usr/local/var/matlab*" to find who is running it. The filenames listed will show when matlab was started, by whom and on what machine. If you //really// need to use Matlab, contact the five current Matlab users, find out who needs Matlab the least that very moment and ask him/her to shut down his/hers Matlab session(s) so that you can use it. Every time all five licenses got used, there was at least a person who simply had Matlab open without actually using it. If a machine running Matlab crashes (the whole machine, not just Matlab), the record of that matlab session will not be deleted from "/usr/local/var". If you see a very old Matlab process record that you are //sure// it is not running any longer (i.e. you checked on that machine with "ps aux|grep matlab"), remove by hand the corresponding file from "/usr/local/var". +
-  - //Some important files in one of the subdirectories of "/net/koko/linux_local/matlab71/" or in "/usr/local/bin" have been altered//. Call the Matlab Administrator to reinstall Matlab.+
