DNS Work

This usually means adding a “*” hostname record pointing at your webserver in your DNS configuration tool.

In Bind you need to set up a wildcard entry to catch anything that a misguided user or bad typist might enter in front of your domain name. Just like when searching or using regular expressions you use an asterisk (or splat) to match any number of any characters the same thing applies in Bind. So at the end of my zone DB file (/var/named/photomatt.net.db) I added the following line:

*.photomatt.net. 14400 IN A 64.246.62.114

Note the period after my domain. The IP is my shared IP address. That’s all you need, now restart bind. (For me /etc/init.d/named restart.)

Now you need to set up Apache to respond to requests on any hostname under photomatt.net. Before I just used the convinence of having a dedicated IP for this site and having the redirect VirtualHost entry occur first in my httpd.conf file. That works, but I have a better solution now. So we want to tell Apache to respond to any request on any subdomain (that does not already have an existing subdomain entry) and redirect it to photomatt.net. Here’s what I have:


DocumentRoot /home/photomat/public_html
BytesLog domlogs/photomatt.net-bytes_log
ServerAlias *.photomatt.net
ServerName www.photomatt.net
CustomLog domlogs/photomatt.net combined
RedirectMatch 301 (.*) http://photomatt.net$1

The two magic lines are the ServerAlias directive which is self explanitory and the RedirectMatch line which redirects all requests to photomatt.net in a permanent manner.

There is a catch though. The redirecting VirtualHost entry must come after any valid subdomain VirtualHost entries you may have, for example I have one for cvs.photomatt.net and I had to move that entry up in the httpd.conf because Apache just moves down that file and uses the first one it comes to that matches, so the wildcard should be last.

That is it, I’m open to comments and suggestions for improvement.

Now i have to get this to work on the Magellan Server or else the project is dead
Anyone want to help?
