I didnt get any response by adding this to my previous post (
http://forums.contribs.org/index.php/topic,43343.0.html) so I thought I would start a new thread. So here is my question:
Before I rush and buy another UPS for my server (I've already returned 2

) I thought I would try the APC Back-UPS ES550 that is connected to a windows machine. But I couldn't get it work so maybe this is me doing something wrong rather than the UPS's not being compatible

I did:
lsusb
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply
Bus 001 Device 002: ID 04a9:107f Canon, Inc. i860
Bus 001 Device 001: ID 0000:0000
then:
config show nut
nut=service
MasterPass=998638045365574
Model=usbhid-ups
SlavePass=753638089762791
status=enabled
and:
upsc UPS@localhost
Error: Connection failure: Connection refused
Am I missing something?
Thanks.
