thats not the point. I got my webserver running(http://myip). I just want to host my own DNS not a free DNS. I have bought a domain.
Doing whois of the domain jurgen-meijer.nl it's obvious that your domain registrar is Lycos Netherlands B.V. and that your current dns servers are:
nshost1.st2.lyceu.net
nshost2.st2.lyceu.net
nshost3.st2.lyceu.net
If tou look at the technical contact e-mail address you will see that his/her domain is webcenter.lycos.nl. Point your browser to this address and login into Control Panel. There should be section for managing DNS servers. If you have problems conntact the person in technical contact for assistance.
I any case you should manage to set you first dns server to be FQDN/IP of your server.
About downloaded rpm see item 3 in my instruction:
yum localinstall smeserver-tinydns-public-1.0.0-4.el4.sme.noarch.rpm
when you where asked Y/N - say Yes and after finish of installation do:
signal-event post-upgrade; signal-event reboot
