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.

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).

Properly overriding caller ID

Written at lunch time in English • Tags: ,

I don’t usually call myself so I hadn’t until recently made note of my own caller ID not being what it should. Looking at CDR logs the caller ID on one of my phones changed in September 2012 from “my” extension to the extension of the phone device. (more…)
