To prevent the NNM scanner from starting automatically upon restarting the system, run the following command:
# /sbin/systemctl is-enabled nnm off
Run the following command and save the challenge string that is displayed:
# /opt/nnm/bin/nnm –challenge

- Paste the challenge string from Step 3 and your Activation Code in the appropriate boxes on the web page.
