The newest version of this tool can be downloaded here: NMIS Support Tool (Version 1.34.60). (NMIS 8.5G and newer ship with the support tool preinstalled.) It needs to be saved in the admin/ directory of your NMIS installation; most commonly that would be /usr/local/nmis8/admin/.
Running the support tool without arguments shows a help screen.
Selftest and Automatic Repair
Starting with version 1.4.0 the Support Tool also runs the NMIS selftest, displays any problems detected - and offers to run NMIS' automatic repair procedure if correctables are detected (i.e. file ownerships, permissions and directory existence are verified and fixed if incorrect).
