Hey all. Maybe this is an expert@ question, but here goes. We're setting up a distance education centre at my church and while the maintenance crew is working on the classroom, from time to time we find that the power to the server room gets cut off. Upon rebooting, the file system almost always has errors and therefore hangs on boot-up asking for the root password before letting the person at the console check the file system and corrent any errors. Question 1. I've used another *nix before (QNX) and know that under it you can limit or just plain shut OFF file system caching. Would this help at all to reduce file system errors if the power to the system gets cut off? Question 1a. How would I limit the file system cache size on the system? It's a P-200MMX with 80MB of RAM. Question 2. Does anyone know of any UPS systems (with software) that works under Mandrake 6.0 to watch a serial port and if it detects a signal from the UPS (that the power is cut) that it will issue a shutdown command? Thanks much. --- Ian W. Douglas, Wild Web Services [EMAIL PROTECTED] ICQ UIN: 506679
