how to update the named server automatically.

Hi all, plz apologoze me if my question does not make much sense. i am creating an application the create subdomain for my clients. after crating the subdoamain i nead to update or resstart the named server to listen the newly created subdomain.so i have there two machanism to update the named server to listen the newly created subdomain--- 1)i update the named server using my java code such as i m getting thr PID of the named process using [b]pgrep -x named[/b] command and then i am using the following command to update the named- [b]kill -HUP 32435(PID)[/b]. but my application does not have permission to do it. 2)i can use automatic dynamic update to named using nsupdate. i m confused, that whaich machanism i should use here in this situation. i am biggener in linux so i do not hve any idea to the nsupdate. Another question can i update the named server every second dynamically(as an background process) to listen the newly created subdomian? Is this a good idea? if someone have any idea of these type of appliation plz let me know the idea. thanks a lot in advance.

Hi, I wrote a tutorial that helps you to create a dynamic DNS server with client updates such as no-ip.com. Follow this link (in portuguese, but you can track only the Linux commands - in bold).
