Accessing the license server at NCKU/ISAPS

We have installed the license key in a server (we will announce the server IP at the workshop), so that all the participants are able to use IDL in the training sessions.  Please configure your client machine to ask for licenses from the server by setting the LM_LICENSE_FILE environment variable.


To define the LM_LICENSE_FILE environment variable, do the following:

Unix/Mac OS

setup the environment variable LM_LICENSE_FILE equal to 1700@140.116.XX.XX

1, bash users
edit the ~/.bash_profile to contain this line
export LM_LICENSE_FILE=1700@140.116.XX.XX
