Fedora Core provides network ups tools (nut). I use nut with an APC Smart UPS 2200, a Tripp-Lite Omni 1100, and several Belkin Universal 1200. The APC Back-UPS series only provides a simple AC/battery indication. Which is fine but you have no indication of how long until the battery dies. (At most a minute or two for an APC Back-UPS 500.) You might consider a Belkin Universal 1200 VA (F6C120). These work well with nut and will run for 5 minutes or so on battery. I've setup two of them this past week. The Belkin 1200 supports USB or Serial and has full AC line and battery monitoring capabilities. The Belkin Universal F6C120 typically sells for $90-$130US. (I've frequently found them for $80US.) On my desktop I run this program in addition to the nut service: http://www.amautacorp.com/staff/Rudd-O/ups-monitor/ ups-monitor monitors the UPS, shows a status icon (AC line, Battery, etc), and when the power fails ups-monitor tells (KDE and GNOME) desktop applications to save their documents and settings. This way if the battery fails prematurely any open documents have been saved to disk. To install nut: yum install nut nut-client To configure NUT for the Belkin I've added the following lines to the indicated files: /etc/sysconfig/ups: MODEL=belkinunv DEVICE=/dev/ttyS0 /etc/ups/ups.conf: [belkin] driver = belkinunv port = /dev/ttyS0 desc = "Belkin Universal 1200 VA" /etc/ups/upsmon.conf: MONITOR belkin@localhost 1 monuser password master -- David Norris http://www.webaugur.com/dave/ ICQ - 412039
