Unfortunately there is a bug in the "Import Devices from NMIS" functionality. Below is a patch and work-around for those that require this before our next release.
This functionality is available for Linux users only. Windows Open-AudIT users are not affected.
Save the attached file to /usr/local/open-audit/code_igniter/applications/controllers/nmis.php
To use the function, log on to Open-AudIT Community (if you are logged in to Enterprise or Professional, click the button in the top right of the menu bar to go to Community) and go to menu → Manage → Devices → Import Devices from NMIS.
Open-AudIT Enterprise will be patched to fix this in our next release.
My apologies for any inconvenience.
