[Nut-upsuser] New UPS Support: Eaton 5S 1000

[Ken Marsh]

Hi,

Thank you for taking a look at this. This is 13.10. I realize Saucy is no
longer supported. This system is slated for replacement, but in the
meantime I'm responsible for it.

The repo version of nut was 2.6.4-2.3ubuntu2. Installing it was useful as
it gave me the nut user and group. The compiled version errors out whether
or not the repo version is installed.

I just did strace. EINPROGRESS seems to be part of some socket connect code
either doing with ldap or DNS. I have no idea why it is doing this as the
upsmon process user "nut" is local, nsswitch.conf has files before ldap,
and the UPS is on USB and in standalone mode. Maybe just boilerplate
library initialization?

The nscd is not running. Kernel is 3.11.0-13-generic so it's a "3" kernel.

The getpwnam is for (ups) not sure if that's a variable or string literal.
If it's a literal, I have nothing named "ups" in the setup, the UPS is
[eaton] and the user within NUT is monuser.

Any more ideas or questions?

Thanks again,
Ken
