As long term readers of this blog might remember, I am involved with the theatre and have built electronics-driven stage props before. However, the last time I used an Arduino to drive an H-bridge IC for a stepper motor, so pretty much low level electrical engineering, with a bit of …

My twitter feed currently is ablaze with discussions about sexism in tech and science. As a member of the social group that goes through life with difficulty set to "easy", of course none of this has happened to me. I don't know what it feels like to go to a …

Recently I was faced with an external program that I wanted to call from my script that only writes its output to a file, not to stdout. Faced with having to call this program a lot of times in parallel, I decided to fake up its output files via POSIX …

Another long and only partially successful day is behind me, and my allocated time for this sprint is over. I said "partially successful", because I did not manage to get GSS-TSIG working. This is mostly due to the fact that I don't understand how to hook it up to GENSEC …

I'm still a but stuck with TKEY/TSIG, unfortunately. While looking at the GSS-TSIG implementation we have in libaddns, I realized that I could simplify my time handling. That ended up fixing my TSIG issues from yesterday. That is, I can now correctly generate the client/request side of a …

Some progress on the TSIG front, but I'm stuck with the exact signing method for a packet. For some reason dig and I disagree on what the HMAC-MD5 of a specific query should be. The RFC is a bit vague, and the BIND code of that area seems to be …

I actually spent my time working out some smaller kinks in the DNS server that I ran into while using it as the only DNS server on my development machine. I also started with restructuring my dns processing code a bit so I can handle TSIGs in a sensible way …

Ok, so I cheated a bit and kept poking at the DNS forwarder code a bit more yesterday after posting my summary. I didn't quite get anywhere final before I went to bed, but this morning, while waiting for my coffee to run through the machine, I got this thing …

Ok, of course this didn't go as planned. It took longer than expected to figure out how to best test my DNS library, which by itself seems to work ok but also only is a thin wrapper around tdgram, so it doesn't do anything fancy yet.

I played with getting …

Samba has it's own small DNS server built in, but it's still lacking a couple of very nice-to-have features. This week, I'll be trying to get as many of those in as possible.

There's two big parts here. One is getting forwarder support, so we can query other name servers …
