Zone Not Loaded - Linux to Windows
I am running a couple dozen websites on a Linux server (Pigpen) as primary DNS and a Windows server 2008 (Linus) as secondary. A while back I noticed that Linus had stopped updating zones automatically when I made a change on Pigpen.
This has been a minor annoyance. All I have had to do is copy the ~.DNS file from /etc/bind on Pigpen to c:\windows\system32\bind on Linus. Still, I had to remember to do it whenever I make a change, so on Thanksgiving day when things were quiet I determined to find the cause and fix it.
Google found me a LOT of possible reasons, but not the one I needed. After examining Syslog here's what I found that fixed it: Windows uses TCP to get zone updates. The rest of the world, apparently, uses UDP.
So I changed
UFW ALLOW 53/udp
to
UFW ALLOW 53
and it works.
Hope this helps, if you are having the same problem.

Harmful to minors
Panic at the London Evening Standard [Sept. 8] where the theatre critic Henry Hitchings filed his review of Lolita at the National Theatre, only to learn that no one at HQ could locate his copy. The panic starts early there – 5am – with production staff looking at the clock and imploring him to file again. Why couldn't he communicate with them. No one could understand it. Enter a hero computer boffin. The firewall, he explained, was rejecting the word Lolita. So Hitchings had to re-file substituting Lolita throughout with the less troublesome "Fishfingers". Relieved production staff re-inserted all the Lolitas at the other end.

After Obama
There were some of us -- indeed, many of us, myself included -- who thought there was a possibility that Barack Obama might seize this moment of American crisis, twinned with the complete failure for all to see of the regressive agenda, to become the second coming of Franklin Roosevelt.

Mr. Franken goes to the State Fair
From dustytrice.com ...
About a dozen tea party activists had staked out Sen. Al Franken's booth [at the Minnesota State Fair], and confronted him loudly when he arrived. But within minutes, he'd turned an unruly crowd into a productive conversation on health care.
