Post subject:  Setting up a BIND server for Dynamic DNS and zero-conf
I'm interested in setting up a BIND server on my Linode, primarily to use with Apple's wide-area Bonjour service. I started playing around last night, but was pretty unsuccessful. I got BIND9 installed to my Ubuntu 8.04 environment, did a very simple configuration just to get going, but get a string of errors in the syslog, and it doesn't seem to be doing anything. This is all a bit of a mystery to me, and I've spent hours researching, but am not getting anywhere. Maybe someone can help?

Specifically, the configuration I envision is this:
- Linode DNS remains master for the whole domain
- I pass the subdomain bonjour.example.com to my BIND service
- I set up the server per the information laid out here: http://www.dns-sd.org/
- I connect my devices needing dynamic DNS to this subdomain, for instance, my Airport Extreme

I've found this so confusing that I'd like to figure out a simple enough setup that I can perhaps write a concise set of instructions, as I imagine this would be useful for others.

Any help would be appreciated. I'm decent at most of this stuff, but DNS is still a total mystery to me.

Thanks.



For reference, here's what I'm getting in my syslog. I've replaced my domain name with "example.com", that's not an oversight.

Looks like it's choking on line 1 of the zonefile:

I wonder if that line is a comment, missing its semicolon... if not, paste what's in that file and someone will surely speculate further.

Exactly right! I didn't realize how picky the conf files were. I have a running BIND now.

Next, I'm wondering if anybody has experience creating a delegated subdomain DNS. I found a decent document here http://www.zytrax.com/books/dns/ch9/delegate.html but it's sort of far from my use.

Can anyone offer experience or advice for creating a delegated DNS like this?
