Page 2 - DNS won't point

no, you shouldnt substitute any of those.....Whats the LAN address of your server, and what model linksys are you using>?

My model linksys router is BEFSR41, and my addresses are:

LAN: 192.168.1.100
WAN: 24.169.144.218

Thanks again for your help!!

Your router has be able to pass info to your nameserver. Your nameserver has to have info in its tables that gives it the info about where to find (resolve) the different parts of your domain (eg www or mail etc).

What operating system are you using? Are you running a unix named daemon or are you using a MS system?

ok. Right now, I'm currently running Redhat Linux 9, and Apache 1.3.29. Ok, so far, my apache is all configured with PHP and MySQL. Everything is currently working. BIND is successfully setup.

When the Linux box is running, when I try to do a DNS lookup, it says TCP connection failed, because of port 53.

Believe me, I've spent at least 2 hours trying to find my answer, and I can't. I've done EVERYTHING to get port 53 open, but I can't. It's not my ISP, because when I was on Windows, it was open, but now it's not. It has to be the firewall.

But I've read many articles, and I just can't open port 50.

I've done the netstat, looking at the "LISTEN" ports, and it's not one of them.

Anything I can do to fix this? Thanks for your help!!

service named start

Fine, now we can move on to other things.

1. do you have a firewall setup on your Redhat box? If so, is it doing the blocking?

2. Is your Linksys router just a router or is it a firewall router come NAT translater?

i.e.

wan ---> linksys ---> Redhat ---> hub ---> internal network

or

wan ---> linksys ---> hub ---> Redhat
|
---> internal network

With the second setup and, say, a Windows box, you could try a DNS lookup on another domain from the Win box. This will determine if the problem is the Linksys unit or your Redhat box.

Because you may have two possible causes I think you need to try to determine which unit is causing the problem.

In your host file for

Do you have both listed like this

coopercentral.org. IN A 24.169.144.218
www.coopercentral.org. IN A 24.169.144.218

Hi:

First off, I know for a fact that it's the Linux Firewall because I used to host my site on a Windows Machine, and I did a DNS lookup just fine. Yes, on my router it has a firewall, but I allowed ports 80, and 53 for both UDB, and TCP.

The setup looks like this:

wan --> router --> internal network

There is no hub. But it definately is the firewall.

When I started the "named" service, I believe that port 53 was open. But when I tryed doing a DNS lookup, it says TCP connection failed on port 53. I know my ISP doesn't block port 53, because like I said, I did this on Windows before. Any other suggestions??? Thanks again, your time you're putting in to help me is greatly appreciated!!
