Good, that looks like a UPS which is supported by the 'safenet' driver,
a driver I maintain.

This is an older version of NUT. Version 2 has been out for quite a
while now, so if you can find this one, please install it.

Fortunately for you, the safenet driver is the latest.

These are all variables that can be set in the 'ups.conf' configuration
file. The protocol that is used ('safenet') is only
'half-smart', in the
sense that the UPS will reply to basically any command with a set of ten
characters, which are not more than status bits. The meaning of these
can be found in the sources of the driver. It is by no means smart
enough to transfer the above mentioned information, so you optionally
can enter these by hand (not needed for operation though, only useful if
you have more UPS-es connected). The man page 'man safenet' will also
tell you that.

Your UPS is connected to the mains and is operating normally.

This is intentional. The shutdown will only be initiated if the UPS is
running on battery and the battery charge is getting low. The reason
behind is in the FAQ:

Q: Why doesn't upsmon shut down my system? I pulled the plug and
nothing happened.
A: Wait. upsmon doesn't consider a UPS to be critical until it's both
'on battery' and 'low battery' at the same time. This is by
design.
Nearly every UPS supports the notion of detecting the low battery
all by itself. When the voltage drops below a certain point, it
_will_ let you know about it.
If your system has a really complicated shutdown procedure, you
might need to shut down before the UPS raises the low battery flag.
For most users, however, the default behavior is adequate.
Ask yourself this: why buy a nice big UPS with the matching battery
and corresponding runtime and then shutdown early? If anything, I'd
rather have a few more minutes running on battery during which the
power might return. Once the power's back, it's business as usual
with no visible interruption in service.
If you purposely shut down early, you guarantee an interruption in
service by bringing down the box.
See upssched.txt for information on how you can shutdown early if
this is what you really want to do.

That depends on your system. Since I do not use Unbutu, I can't help you
there. Rest assured that NUT *is* working correctly.> My questions are:

Yes.

As stated somewhere in the README's, you may want to try this out before
going live. Power your computer straight from the mains and pull the
plug on your UPS. When the battery charge is going low, NUT will inform
you about that. You can also follow this with the 'upsc' if you want
too, since that will also show you the status of the UPS.
