Ok. We'll finish pouring the cement then. :)

Aha, ups owned by root:415. Nuts number changed and I didn't fix it. Have
now, and it works:
[root at coyote etc]# /usr/local/ups/bin/upsdrvctl start
Network UPS Tools - UPS driver controller 2.4.3-2672M
Network UPS Tools - Generic HID driver 0.35 (2.4.3-2672M)
USB communication driver 0.31
Using subdriver: Belkin HID 0.12
[root at coyote etc]#
So I'm past that (again). On to step 9:
[root at coyote etc]# cat upsd.conf
LISTEN ::1 3493
LISTEN localhost 3493
[root at coyote etc]# cat upsd.users
[gene]
password = gh10041934
actions = set, fsd
instcmds = all
upsmon master
Looks ok, so step 10
[root at coyote etc]# /usr/local/ups/sbin/upsd
Network UPS Tools upsd 2.4.3-2672M
listening on localhost port 3493
listening on ::1 port 3493
/var/state/ups is world readable
Connected to UPS [coyotes-ups]: usbhid-ups-coyotes-ups
looks ok.
11.
[root at coyote etc]# /usr/local/ups/bin/upsc coyotes-ups at localhost
battery.charge: 100
battery.charge.low: 30
battery.charge.warning: 30

battery.voltage.nominal: 24

etc etc
But how about gene?
[gene at coyote linux-2.6.36]$ /usr/local/ups/bin/upsc coyotes-ups at localhost

battery.charge.low: 30
battery.charge.warning: 30

aka yes!
Ok, how about the init.d/upsd script?
Nope, back to the perms problem
[root at coyote etc]# /etc/init.d/upsd restart
nutuser=gene
nutuser=gene

So, how does the nutuser=gene get access to ups.conf? (appending ',gene' to
the group of ups & nut didn't help. gene can run it from a cli, but that
script can't.
I have attached it as it exists now.

That was as stated in the INSTALL file.

I have 4Gb here, with a slow phenom 9550, asus m2n sli deluxe board. pclos
is the snappiest os I've had on this box in yonks.
[root at coyote etc]# udevadm --version
156
Take a look at that starter script I attached & see where it needs help if
you can, and thanks, Charles. I'm going back to bed. ;-)
