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.

Windows

To define the LM_LICENSE_FILE environment variable, do the following:

Open the System control panel.
Click the Advanced tab, and click the Environment Variables button. Click the New button below the System Variables box and enter the following information:
In the Variable Name field, type LM_LICENSE_FILE in uppercase letters.
In the Variable Value field, enter your server's port@host value: for example, 1700@140.116.XX.XX. This information is in your license file. The port number is the last number on the SERVER line. The host name immediately follows the word SERVER.

If LM_LICENSE_FILE has already been defined for another software product, the definition of this license file can be appended using a semi-colon (;) as the delimiter. For example:
C:\Program Files\ITT\License\mylicense.dat;1700@140.116.XX.XX
save the settings.

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

Mac users are similar, add it in ~/.bash_profile
if they need to start idl by GUI instead of bash terminal cli, try to
edit ~/.MacOSX/environment.plist
refer to this link

2, csh/tcsh users
edit their ~/.tcshrc or ~/.cshrc file with
setenv LM_LICENSE_FILE 1700@140.116.XX.XX
