Once these changes have been made the user will need to log out and log back in for them to take effect. If you used pico hit Ctrl-X then press Y when prompted to save the file and Enter to accept the filename. Depending on the login shell defined for the user in /etc/passwd it may be necessary to set up both sh/bash and csh/tcsh style this file. LinuxĪ common approach to setting system-wide environment variables is to create files in /etc/profile.d which are executed when a user logs in. You may set these variables any way you see fit. In each case the environment variables for all the above applications are included, but keep in mind that these are just samples. Below are examples of how to set up system-wide environment variables on linux, OS X, and Windows. How environment variables are set depends on the operating system the application is running on.
FlexLM environment variables (Abaqus, Ansys, Comsol, Matlab)Īll remaining applications utilize environment variables for license management.
If a user wishes to run one of these applications remotely they will need to use a VPN to connect to Tufts first, at which point they should be able to check out licenses. The license servers are firewalled to only allow connections from within Tufts. is the master license server so it is typically listed first in the environment variables.
In each case the three license servers are, , and. The environment variables list the hostnames of the license servers and the network ports that the license servers listen on. Local license files are not necessary in these cases. For most applications it is a simple matter of setting an environment variable that the application will use to locate the license servers. As long as two of the three license servers are operational they will allow applications to check licenses in and out. Tufts operates a cluster of three FlexLM license servers that provides redundancy in checking licenses in and out. People using these applications can configure them to check licenses in and out from the Tufts license servers using the instructions outlined below:Īll of these applications but Mathematica and TecPLot utilize FlexLM for license management. Tufts operates licensing servers for the following applications. Tufts Application License Management Introduction
