Remote access

To run ATK/VNL directly on your computer (as opposed to running remotely and sending graphics over the network), follow these steps on your computer to prepare for and launch the application.

Preparation

  • Modify your configuration for SSH port forwarding on Mega. On Mac or Linux, make the changes to the file ~/.ssh/config . On Windows, consult the help pages of your ssh aplication.
Add two entries for Remote Forwarding:
Local port: 6200,   Remote Port: 6200@cmgmt3
Local port: 6201,   Remote Port: 6200@cmgmt4
Note that the local port is different but the remote port is the same between the two entries.
  • Log out from all Carbon nodes.
  • Log out from Mega.

Download, Install, and Configure

  • Log back in to Mega. This will activate the tunnel configuration that you added previously, to be used later by the ATK License Configuration wizard.
  • Download ATK from QuantumWise
  • Follow the installation instructions until you reach the license configuration step.
  • In the License Configuration helper, choose Configure license settings, Advanced setup. In the field for QUANTUM_LICENSE_PATH+= add:
localhost:6201@localhost
  • Finish the helper.

Launching ATK/VNL

  • Make sure you are logged in to Mega.
  • Start VNL or atkpython normally for your platform.
