Hmmm...is there some particular reason you're concerned about SCO Sys V? (Is the power requirement for SCO different from AT&T, Esix, ISC, Dell?:-) I think of UPS concerns as being mostly hardware issues; we'd benefit from broadening the discussion. Seriously...we've been 'round the UPS discussion a time or two, but only lightly; it wouldn't hurt to run it again with updates. (I think we left a question about Unison hanging; that ought to be cleared up now.) One of the things you need to talk about is what sort of hardware you're trying to supply--one little machine, a big one, a flock of 'em? If you really have SCO-specific questions, what are they? > 2) How do I get the U.P.S. to tell the machine that > it is running on "borrowed time" and to do a shutdown? UPSes which are set up to do this generally talk down a serial port...so you need a spare serial port and a little program to kick off the shut- down. -- Dick Dunn rcd@ico.isc.com -or- ico!rcd Boulder, CO (303)449-2870 ...If you plant ice, you're gonna harvest wind.
