ISPConfig is not resolving DNS queries.

[demortes]

Hey all,

I'm looking for some advice, if not a solution, to why my name server wont set up.

Here's what I've got. My server with Debian Linux and ISPConfig. That all works fine, as far as I can tell. It sets up fine, controls everything fines, logs in fine. That computer is just great. Now it's behind a router, Linksys WRT54G flashed with DDWRT Standard. Internet access is fine. Behind that router is also a desktop computer with Windows XP Pro and Ubuntu on it, and two Xboxes (One original and one 360). Enough of my networking setup physically.

Currently, I have the server in a DMZ. This is after doing port forwards and whatnot. I registered NS2.SERENITY-TECH.COM as a name server. For the secondary DNS, I set my zoneedit account as slave. It's set to pull from my name server. Now, I've done everything I could possibly think of, and my name server will not resolve the names it needs!

Given the fact that it may take 2 days to propagate the DNS, I'm tired of waiting. I need someone more advanced in this area to help me out.

How should I have this set up? What file can I check to make sure the DNS files are being written properly? What other tests can I do?

Who you're dealing with: A computer guy with expierence in a little of everything, Linux, Windows, C, C#, C++, QBASIC, networking physically, network setup, troubleshooting, hardware (putting together computers), software (install of everything from OS to utorrent).

Thanks for help in advance,
Kevin

Currently, I have the server in a DMZ. This is after doing port forwards and whatnot. I registered NS2.SERENITY-TECH.COM as a name server. For the secondary DNS, I set my zoneedit account as slave.

I'm take it that your secondary server is in your private network? I can't comment on the Linux config, but the way I do DNS for the private and public networks I can. Wether I am hosting my own or using a provider for external DNS, I keep my internal DNS (private) separated, meaning no zone transfers. To resolve names on the Internet you can use root hints or a forwarder. My first choice is to use root hints. In you case, since it sounds like you are hosting your own public DNS (In your DMZ), I would investigate how to set up a forwarder on your internal DNS. Any query for a host record on the internet (internally0 will be forwarded to you external DNS for name resolution. I hope that I am understanding your environment as you stated you set the internal DNS as a slave. Again, not sure if that is Linux speake for doing zone transfers.

I'm getting failures querying ns2.SERENITY-TECH.COM, can you query it successfully internally using nslookup on the Windows XP machine?

 

[demortes]

I can NSLOOKUP it, yes. WhoKilledKenny just confused me.

So what, the IP just isn't forwarded right?

 

[demortes]

Just found something out. I went to my address bar in firefox and typed ns2.serenity-tech.com and it points to ISPconfig as a website, the test.serenity-tech.com website.

 

[demortes]

Just thought I'd let you guys know, NS.SERENITY-TECH.COM is now the primary, NS2 and NS3 point to the IP's handled by zoneedit.com which are set to copy from NS (after you can reach it.

After realizing I answered the NSLOOKUP question wrong (typed NSLOOKUP NS2.SERENITY-TECH.COM instead of NSLOOKUP FIREFLYTHEMUD.COM NS2.SERENITY-TECH.COM) I did it right, and it says server failed, on anything I use.

Hope this is the information you NEED to help me. I have a feeling that Bind isn't answering correctly.

Sorry, didn't mean to confuse. Just trying to understand your setup...

HOpe this works....

Now the server is DMZ. (Changed NS2 to NS for the name server and pointed NS2 and NS3 to zoneedit NS's.) Has BIND9 with Debian Linux.

I only have the one server... any other questions or did this not help at all?
