Linux DNS Question

[pgp_protector]

Question.

I'm trying to setup a laptop to run Linux (Ubuntu 8.04 is on it now)
I'm going to be using it for web development & play

What I want to know is how / if I can set up a DNS server on the laptop to do the following.

I own the domain xyz.com (not really xyz, but will work for this point )

So If I set my main computer to use the laptop DNS as it's DNS server I want is to that if I go to www.xyz.com, it will go to the internet site xyz.com as normal.
But if I go to test1.xyz.com, it will then use the Laptops web server to serve the pages in the subdomain test1.xyz.com.

So
1) Is this possible
2) If so, how do I configure it ???

It's possible. You need to set a CNAME record under the main domain to point to where you want the site to go.

For web development, it would be better to setup a dummy DNS name for testing, ie. xyzlocal.com . This way when you want to copy your code across you shouldn't need to make any changes to it. For simple web design (not development), the above wont be an issue though. Modifying your hosts file and restarting the Apache client should be enough to get this to work.

Not sure how it works for the sub domain being local and the regular domain being live.... If you rely on the CNAME change, you would need a way to redirect the DNS requests back from the internet to your computer with a dynamic DNS provider. I think this way is not as clean and relies on many more pieces, meaning more chance of errors and headaches....

If you can, try both and see which suits you better

Not sure do you still need help, but you'd have to provide more precise data. My guess is that you're interested in setting up BIND on your laptop, and you want that laptop and some other computers from internal IP address range to use laptop as a DNS server? You also want to have a single record on laptop DNS, named test.xyz.com served from the laptop, but, for instance, "www.xwz.com" name resolution, forwarded to a public DNS? If my assumptions are correct - try this, partial, solution: http://groups.google.com/group/comp.protocols.dns.bind/browse_thread/thread/8baadcffb64c3ac2
