This information was captured as a user other than root, since when I try
any of the commands as root, the machine locks up and I have to power
cycle. I will capture that information also and send it to you next.

BTW, I was running the find-scanner command as root, but the others as
another user. Then when I changed the permimssions per Markus's
recommendation, I could run find-scanner as user. Sorry for the confusion.
