I have seen free forum hosting like freeforums.org creates subdomain with register form on website.

I would like to generate subdomain using data from register form on my website (generate subdomain as soon as user complete registration form, no control panel login ) .

Someone tell me that I need shell scripting to control DNS.


How to do something like that ?
or
Any exsample ?


Thank you.

I imagine by using BIND with a mysql layer to store the configuration.
http://mysql-bind.sourceforge.net/

But BIND can be a real hell to configure, if you don't exactly know what you want to do.

Document yourself good before starting it, by having a base configuration that works, before trying to extend it with subdomains.

just a thought..is wildcard subdomains not an option? You could use that in conjunction with a htaccess file to get the xxx from xxx.yourdomain.com and use that variable to dynamicly display the needed content.
