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

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.read more
So, yesterday was the big day. The Coming of The Tablet. I'm not exactly a big tech pundit. I've never seen an iPad in person. I haven't even played with the emulator yet. But I thought I'd still post my immediate reactions.
The Name: It's not that bad. It doesn't trigger the same juvenile "feminine products" joke urge in me that that it does with all of the commentators on Slashdot. It kind of reminds me of PADDs from Star Trek, which is a good association for a high-tech device. It's better than "iSlate" would've been. I think "Apple …read more
Hey all. One of the sysadmins at Mudd, Claire Connelly, pointed out that there's a widespread bug in SpamAssassin that might cause large numbers of false positives on mail sent after 2010-01-01. Apparently, the "date in future" rule is hardcoded to look for years after 2010. You can read more at LWN; the short of it is that you probably want to add the following to your SpamAssassin config:
score FH_DATE_PAST_20XX 0.0
sa-update may or may not be pulling down updated rules. You can find
the relevant bug at the SpamAssassin Bugzilla (#5852). Anyhow,
something fun to be aware …
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.
