I have recently got linux yellow dog for my ps3. Since i've installed it, I've been getting the message -do not have permission- on about everything i try to do. How do i change my security settings to fix this problem? Its linux yellow dog. (red hat nash) ver 6.0. I would also like to know how to restore to default. Just like it was when I first started it. Can that be done? Again ........Thanks for the support.
