I have an interesting problem. I have a pair of servers, one Windows 2000
and one RedHat Linux 8.0. They are both sharing the same UPS, but only one
can have the signaling cable. I'd like to know if anyone knows a way of
sending a shutdown command from the Windows server to the Linux server when
the UPS signals that the power is out. I'm open to hooking the cable to the
Linux server and having it shut down Windows, but I think it may be easier
the other way around.

Any thoughts?

Possibility 1: See if the UPS vendor has any Linux support. (TrippLite
had remote-shutdown software for Linux at one point. Not sure if this is
still the case -- it's been a few years since I last used their tools.)

Possibility 2: Take a look at the NUT (Network UPS Tools) project. The
Linux software is already on your RH 8.0 Installation CD #3 (check the
RedHat/RPMS/ subdir, look for nut*.rpm). Windows is supported, but only as
a client (i.e., you'd need to have the Linux box monitoring the UPS) -- you
can find the Windows software on the NUT homepage:
http://www.exploits.org/nut/

It'd probably be a good idea to check the NUT site's compatibility list
first to see if your UPS is supported.

Cheers!
