The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

DNS Woes

Mark wrote in today to say that reverse lookups for my domain weren't working properly. And lo, nslookup was having a hard time finding the machine it was running on.

At first I thought maybe it was a problem with what I was trying to do with the latest version of bind. You see, I set things up such that I control the reverse lookup on the 32 IP addresses Atlantic Internet provides me.

This is done via an interesting hack. For the appropriate in-addr.arpa file, I have:

0	IN	NS	linus.slab.conman.org.
1	IN	NS	linus.slab.conman.org.

And so on for the 32 addresses I've been assigned. Then, for the namesever here in the Computer Room, I have:

1	IN	PTR	isdn.slab.conman.org.
2	IN	PTR	area51.slab.conman.org
3	IN	PTR	linus.slab.conman.org.

32	IN	NS	ns1a.aibusiness.net.
33	IN	NS	ns1a.aibusiness.net.

253	IN	NS	ns1a.aibusiness.net.
254	IN	NS	ns1a.aibusiness.net.
255	IN	NS	ns1a.aibusiness.net.

I've also set the nameserver to think it's a master for the in-addr.arpa zone I appear in.

So anyway, I thought the latest version of bind wasn't liking that. And it turned out that was true, to a degree.

There is no such TLD as .apra. Stupid typo.

Obligatory AI Disclaimer

No AI was used in the making of this site, unless otherwise noted.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: https://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

https://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.
