Sounds good. You mention that NUT was installed via apt-get. Just to confirm, has another version of NUT ever been installed on this box by hand (i.e. download and build from a source tarball)? > I am trying to also add an NAS to the system as a slave, so that as soon as > the server shuts down, the NAS will also shut down, but I can’t get NUT to > listen to anything.
