Own name servers

[kini]

Hello guys!
I need to have my own name servers, but i have only one server with one ip address.  
How i can do it ?

check the documentation
http://docs.sentora.org/?node=95

I read this but i dont know something in this guide..

Where i need to this - in sentora or in my domain register (godaddy)?

Code:

A Records to set at your domain REGISTRAR:
*         xxx.xxx.xxx.xxx     1 Hour
@       xxx.xxx.xxx.xxx     1 Hour
mail    xxx.xxx.xxx.xxx     1 Hour
ns1     xxx.xxx.xxx.xxx     1 Hour
ns2     xxx.xxx.xxx.xxx     1 Hour
www    xxx.xxx.xxx.xxx     1 Hour

CNAME Records to set at your domain REGISTRAR:
panel         @     1 Hour
ftp         @     1 Hour

1. In my domain register (godaddy) i insert my ns servers and after this godaddy say "i cant control this domain, he is on another name servers".
2. I added my ns servers in sentora.

And now what?


EDIT: my domain now stopped working after these edits?

In my register i added ns1.mydomain.com and ns2.mydomain.com

And this images show what i did in sentora panel:

Tell me where is my wrong, please?
