I am settimg up DNS on a Fedora 11 box. I have 1 Linux server (linserv1) and 1 linux client (lincli1). at the same time, I have one 1 windows xp and 1 windows server2003(windc1). Linux server is the Master DNS server resolving request from linux client box. I am authorizing windows server box to resolve for windows client. I have a domain called corp.com on linux server which is the master. at the same time time I have the domain for windows server called ad.corp.com.

Once I use the command "Host linserv1.corp.com" to see if DNS is working I recieve an error which ;; Connection timed out ; no servers could be reached

I have the following configuration on my /etc/named.conf
//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

forwarders { 192.168.2.1;
};

};

include "/etc/named.rfc1912.zones";

include "/etc/named.dnssec.keys";

Here is what I have in /corp.com.db

Here's a couple of things to check:

Did you open port 53 for both tcp and udp on the server's firewall?
Did you start the dns service on the server?

If the answer to both of those questions is yes, do you get the same result running the host command on the linux server and client? Can you ping the linux server from the linux client?

Also FYI - it sounds like you're working from Moskovitz's "Windows and Linux Integration" book. If you are, be aware that there are some things in it that are very out of date, particularly with Fedora. Since the book doesn't bother to explain how a lot of the stuff works, but just says "do this...", be prepared to do lots of research to find out how things work now.

Hello Bill,
Yes Port 53 for UPD and TCP is open. The Named service is also running. I should mention that I am running the host command on the server itself. At the same time, both machines can ping themselves and eachother. It is Moskovirz's book right, but I used both Webmin and System-Config_bind utility. I worked around it in different ways, but receiveing the same error. It is killing me. Please help. By the way, do you know where the zone files are? in the configuration information that posted where is it linking to the zone files? thanks

who is the 'nameserver' in your /etc/resolv.conf ?

Nameserver 192.168.2.202 which is my linux server mashine IP. Please correct me if I have done anything wrong or if I should take further steps. I configured a master zone which is on my linux server box. I have three A recored for linux server box, linux client box and windows server box. Thanks

You name server only listens on your loop back address as per your configuration.

In this scenario, make sure that your /etc/resolv.conf states following.
If this server is going to serve a particular subnet, you need to add corresponding interface ip in the server in the listen on and allow-query directive.

After this modification, make sure to restart your server and check to make sure that 'named' is running.

Thanks for your help. It worked.

I am glad that it worked. Dont forget to Click on the "Thumbs up" it is helped you. :-)

Where is "Thumbs Up"? I am new here. Thanks
