- Build a primary DNS centos 4.3 server, and make the
required efforts to configure it properly. Do the required effort to have a secondary nameserver, like using granitecanyon or other similar service if you don't have the physical hardware just yet. I use Bind for my dns servers.
- Ping it on it's static IP from a remote machine to assure
it can be seen, specifically on port 53. You can usually block all of the other ports with your firewall.
- Aim your registrar/ domain name at this new IP as the
"primary nameserver". I find that using web forms are less cooperative than contacting the registrar's tech support by phone and having them make the change. Web forms have error checking, sometimes accurate, sometimes false positives. Either way, the human can say things like "i'm not seeing that on ping or nslookup/dig the same as you, let me check into that".
- Audit your entire setup, bring it online. Try using
weekends for testing.
- Buy a good DNS book, or download one of the FAQ's, join
mailing list for bind or other technology, and use programs like tcpdump and ngrep for testing. I like ./ngrep '' port 53 or similar because I can see the server start to contact root servers as it propagates.
maybe i'll make a basic howto "Installation & Configuration of Bind on centos 4.3" and submit it.

Hello karlski,
I'd look forward to reading your howto. I doubt I can setup this myself as I only have 1 stactic IP at this time. :-(
On a side note, I have several virtual host running on this IP and have zone files for each. Do these virtual host need reverse or in-arpa files as well? (my terminolgy my be wrong)
Thanks,
Eddie
Hello,
I have recently switched from having a dynamic IP address
and using a
DNS service like zoneedit and dyndns to having a static IP address.
How do I stop having to use these DNS services and use my own? I tried changing the DNS servers at my registrar but it won't
accept my server.
TIA
