Unbound not resolving

Written in the mid-morning in English • Tags: , , , ,

I’m not sure what failed last night, but I’m guessing the cable Internet connection was down. Interestingly, unbound had stopped resolving even local zones configured with stub-zone and stub-addr directives. This was unexpected: stub-zones are supposed to work “without referring to the public Internet” per the unbound.conf manual page.

To mitigate the issue I wanted to have backup name servers in resolv.conf (ones using a different Internet connection) even on the resolving name server hosts themselves. With resolvconf that boiled down to creating /etc/default/resolvconf with the following setting in it:

TRUNCATE_NAMESERVER_LIST_AFTER_LOOPBACK_ADDRESS=no

This way name servers configured in /etc/network/interfaces (using dns-nameservers directives) are included in resolv.conf even when unbound has been started.

However, this is a poor workaround, as I don’t have multiple Internet connections at every site.

Finally figured out why Startup: Never doesn’t work in Parallels: I was being bitten by Lion’s resume feature. To actually obey the startup and shutdown settings of each virtual machine, one needs to select Disable Resume for Parallels Desktop in its settings.

DSM 4.3 has been released. A more complete list of new features can be found in the old beta announcement. Upgrades went smoothly. I think next time I should update all packages before upgrading DSM.

When I click on Preview in the WordPress editor, Fluid makes a GET request to the web server. It still uses the action address specified in the #post form (post.php), just not the POST method. But none of the form values are included, so I end up staring at a listing of all posts instead of the preview I wanted. Maybe it is getting confused by the fact that the #post-preview “button” is actually an HTML link (an a element)? There is also some JavaScript that attaches to the click event of the link (see the doPreview() function).

Blockquoted code blocks

Written in the mid-afternoon in English • Tags: , ,

I’ve been writing in Markdown for nine years now, because it allows me to spend more time on content as opposed to formatting. Using it with WordPress has required a couple of bug-hunt sessions, but overall I feel it has been a time-saver.

This week I spent a little bit of time experimenting with formatting code snippets. While looking into my earlier writing I realized I’ve had an issue with code snippets repeatedly. Today I took the time to fix the problem by changing the Markdown parser slightly. (more…)

Wheezy upgrades

Written late in the evening in English • Tags: , , , , , , ,

Debian 7.0 “wheezy” was officially released about a week ago. I’ve been running it on a couple of systems for a few months already because of the more recent software versions available on it. Today I upgraded one of the shell servers, a couple of days ahead of the originally posted schedule due to security updates to MySQL (DSA-2667). As usual for Debian, the upgrade process is well documented1 and robust. However, here are some notes for upgrading the next instance. (more…)
