You've neglected to search the forums first (this question has been asked and answered many times), you've not install a Split DNS set-up and you need one - that was your first mistake.

That was your second mistake, you should set it to your domain name.

Hardly surprising with the above problems.

Thanks a lot for your support. i will go through that article. i will contact you if i get another problem.

I have downloaded bind from the following location.

Download BIND 9.7.4 bind-9.7.4.tar.gz | Internet Systems Consortium

i ran the following scripts.

./configure
make
make install

but there is no /etc/named directory in my system. I am using RHEL 5.3 Server edition. I don't have the RHN key. so i can't use yum.

kindly guide me.

Why did you do that? You'll find that BIND is already provided in your distribution.

i could not find bind in RedHat Enterprise Linux 5.3 Server edition. Where can i find it?

I replaced my RHEL 5 with CentOS 5.6. these are my configuration files.

/var/named/chroot/etc/named.conf

options {
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
forwarders { 8.8.8.8; };
};
include "/etc/rndc.key";
// We are the master server for zimbra.com

zone "zimbra.com" {
type master;
file "zimbra.com";
};

/etc/hosts

You need to look in your server log files to find the reason it failed to start.

i don't have bind installed on RHEL 5. moreover i tried to install it but i can't understand the problem. it is installed fully but there are no associated directories or files created of bind. no named service. i spent a lot of time but could not solve that. kindly help me out. is there any alternative to get out of this problem? i have installed webmin1.560 on the same machine. but there is no bind server listed in the servers portion. can i do the same job using webmin without bind? is there any other alternative? please help me out.
