Go ahead, ask

altivoAfter that last one, where I did what amounted to prying into private thoughts (or so it seemed to me at times) I feel as if I should give you all a chance to get even. I don't think I've done this one, though I've seen others try it.
Ask me anything. No holds barred, though in a few cases I might answer in private rather than here. I will try to answer anything honestly if you want to ask.
In other news, rain, rain, rain. Power has gone out twice today. The first time it took down the network at the library. Or at least, they thought it did and called me. I was puzzled at first because it was a short outage, under ten minutes, so everything with UPS protection should have just stayed up through it.
Turned out that the local name servers had shut down on UPS command, after five minutes. Once they do that, the UPS is supposed to kill the power. When the power comes back on, they restart themselves. Well, the power came back on before the UPS itself shut off, but after the servers had closed. Consequently, neither one woke back up. The network connection was live, but everyone there thought it was dead because everything they did to test it depended on getting a DNS response first. I'm going to have to hard code an external IP for an alternate server on some machines to get around this. I've given up on getting anyone else to actually understand the distinction and diagnose it without my help.
