I am trying to setup virtual subdomains using Bind9, following this tutorial.. http://groups.drupal.org/node/16862 which I've completed. Basically setting up the zone and modifying the resolv.conf file and the named.conf.local file.

I've gotten everything to work, and I am able to from my server ping mydomain.com , test.mydomain.com and when i do a dig I get the following..

; <<>> DiG 9.7.0-P1 <<>> test.mydomain.com
;; global options: +cmd

So it looks like everything is working. However, when I try and do test.mydomain.com in the browser, expecting it to default for now to mydomain.com it does not work and I get a server not found page in Firefox.

I did read elsewhere that in your virutalhosts file you also need to setup a *.mydomain.com alias, but that didn't fix anything.

Any other information that I could provide to help troubleshoot, or any troubleshooting suggestions?

I am using Ubuntu 10.4, with typical LAMP setup. The only other things installed on the server are Bind9 and ftp client.
