Nut upsuser - Aug 2007 - upsc "Error: ... Can't assign requested address"

Hello there.

I've just install nut 2.2 from source on my FreeBSD box. I have an MGE
AVR 600 UPS on a USB cable. Following the INSTALL instructions,
everything works in term of the USB driver detecting the right UPS and
upsd loads up and runs without error.

However, upsc reports the following error:

   # upsc mge600 at localhost
   Error: Connection failure:Can't assign requested address

I was having this trouble with the FBSD ports version of nut v2.0.4,
hence the source build of 2.2. Whilst other things are working much
better with 2.2 (like the upsd driver auto-driver load, which wasn't
before), this "address assignment" problem remains.

(I have no firewall activated, if that's of any relevance).

Many thanks for any help!

I am by no means a FreeBSD expert, but I do have a test machine that I
can try this with.

A couple of questions:

What version of FreeBSD are you running?

Is IPv6 enabled?

I think that's part of the problem - the loopback interface does not
have an IPv4 address assigned. In a normal IPv4 setup, "localhost"
resolves to 127.0.0.1, which should be bound to the loopback
interface.

I forgot to reply to the list with the answer. Thanks again Charles!

Thanks Charles! You're absolutely right my man. I never even noticed
the missing IP4 address! How bizarre.

I've now assigned an IPV4 address of 127.0.0.1 to lo0, restarted the
nut ups driver and upsd daemon and now everything is working fine. :-D

Thanks so much for helping out with my domestic blindness on this cool
morning here in New Zealand :-)
