Since these links are there so I can copy files from any of these machines to this one, or move a network acquired file to one of those machines, is your version of permissions adequate for that? I don't really think security concerns are relevant here as this whole network is behind dd-wrt, and no one whom I didn't give login creds to has succeeded in penetrating this network in the 15+ years I've been using dd-wrt in my routers. And I AM the only user sucking air. The wife is 75% dead from COPD, I have been her caregiver for EVERYTHING for the last 3 years, and she has never had any interest in using my computers even if she's had an account off and on for the last 30 years. > Don't just randomly throw 1777 or 777 or 666 permissions on > everything. See the question above. I will restrict it, until it gets in my way the first time. Thanks Greg.
