Finally got djbdns running at home. For some reason it took me ages as I kept putting the wrong addresses in resolv.conf, or the dnscache environment, or something else over and over again. I think setting bind up would have taken me longer, and I wouldn't have been confident I'd done it securely. Learning a bit about DNS doesn't really make up for being ill and missing a band on a friday night, but my computer's a bit better now. bah. I think I quite like DJ Bernstein's svscan alternative to init.d for starting and stopping services.
bgeiger: to get Mozilla to do a tooltip style popup use the title attribute. The standard specifically says it can be rendered as a tooltip in visual browsers, it says no such thing for alt. title can also be applied to any element, not just <img>, try it with <span> around some text (in a good browser anyway). If you must use tooltips you can put the same text for alt and title to do a tooltip that works in Netscape4, Mozilla, Konqueror, Opera and IE. And that's why Mozilla won't change.

Update: oops, that "more accessible reference" was a local file on my hard drive! Fixed to point to the online version
