dnsextd, TCP, and IPv6

Posted Tue 02 March 2010 17:45 under category programming

Hello interested parties. dnsextd (in my git repository) now supports TCP. It was actually sort of an amusing bug. I guess the dnsextd code must date back to PowerPC, because it had an extra ntoh call which on little-endian systems would cause TCP requests to fail. It's fixed in the "tcp" branch of my git repository. In case you're curious as to how to get that repository, you would use the following:

% git clone http://files.roguelazer.com/projects/mDNSResponder-214.git
% cd mDNSResponder-214
% git branch --track tcp origin/tcp
% git checkout tcp

If you need more setup help ...

So, some news on the wamupd front. I just released version 0.1.1 (tagged as such in git; also available as a tarball at http://files.roguelazer.com/projects/wamupd/wamupd-0.1.1.tar.bz2) which has a lot of new features over the prior, unnamed release.

  • wamupd now stays resident, renewing leases and such
  • It can talk to Avahi over D-BUS and pick up other services registered on the computer (sort of; it's kind of hack-ish)
  • Lots and lots and lots and lots of bug fixes

I've got ideas for the next few releases (still looking ...

Dynamic DNS: Part Two

Posted Mon 15 February 2010 23:18 under category tips

Bonjour This post is a follow-up to Dynamic DNS

When last I left you, we had basic updateable DNS running and could update it from OS X. I've been a bit busy since then, but thanks to some prodding from @Loredo, I got back in and started looking at. What follows is the exciting story of how I got things up and running -- by the end of this post, you'll have access to a working copy of dnsextd for linux, and a client application that updates SRV and IP (A/AAAA) leases. Woo.

*nix Tip of the Day: Dynamic DNS

Posted Fri 18 December 2009 16:29 under category tips

Bonjour logo

It's nice to have DNS records for all of your computers. It's a giant pain in the ass to remember IP addresses, especially if you're on something like a cable connection, where the IP address is dynamic (but only changes every month or two). Now, you could go ahead and use DynDNS or No-IP or something. But those are lame. You have to use a subdomain of one of their domains, and you have to use their software to update. You might be wondering if there's a better way. Well, there is. Standard DNS supports updating, it turns out. In BIND, this is managed through the allow-update parameter. I had some free time this week after I finished finals, so I went ahead and set it up, along with the other trimmings required for Wide-Area Bonjour. It's cool, so I thought I'd post a bit.

The most important resource for all of this stuff is dns-sd.org. Aside from a couple of minor errors that I corrected and an update for OS X 10.5+, this Tip will be based off of the guides from that site. So credit to them.
