We want to run PFC2D on an HPC cluster,  
The cluster does not have internet access, however there is one node in the cluster which is connected to the internet,  
it is 40 cores and runs well, but the compute nodes do not connect to license server, We need to allow the compute node to connect to Master Node and allow the license forwarding to take place through the master,  
CLOUDFRONT -\>\>\> [MASTER] -\>\>\> [COMPUTE]

Rather than

[INTERNET] → X → [COMPUTE]

We want to create the license key fingerprint on master node for Linux
