I've been using Debian Linux for several years but will admit that I'm pretty dense in the password/security area. I normally don't have to worry much. I have a good firewall and don't have much to steal.
I usually log in as su and operate from the X11 terminal in that mode. I have been having problems getting locked out of my own files because they are marked as root:root rw-r--r--. I just started doing some GUI programming with C++ and Qt (great package) and am getting the following error at the end of the compile cycle:
Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
I suspect a permission problem but don't know what to change. I'm a little busy right now and would like to avoid a major research project to solve this. I've had too many of them lately.
