I suspect that I tried to re-boot while something unlocked was running but the upshot is that I can't login as root. However, I had previously established myself as a user in the sudoer list with ALL access so I can login as that user (with rw privs). I've checked Messages but with the exception of an irrelevant printing module (char-major-188) that cannot be located during boot I can find nothing to indicate where my problem lies. The boot.log isn't helpful either. The secure log wasn't any help either though it did report that the "root" listed in sudoer is "unknown" According to what I've read about pam, I believe I can remove the password requirment for root from the console (to which I have full access) but I'd rather fix root's login problem if possible. If there's a troubleshooting HOWTO I've missed or a site where this kind of problem is discussed, I'd appreciate the information. Since I've run out of my own guesses, I'd also appreciate any advice listers have to offer. I'm running FC1 (2188). Karl L
