configure DNS server on solaris

Hello evrybody

I need to know how i can implement and configure DNS server in solaris9 and i need to understand which files i modified it to do that

Thanks all
# 2  
Download this template(http://developers.sun.com/solaris/technotes/named.tar.Z) to a work directory, such as /var.
To unpack the file, at the command line type:

zcat name.tar.Z | tar xvf -

For quick installation, do the following:

1.Determine what type of DNS you want and what support information you need from your network provider, such as global caching DNS.

2.Edit the named.* files you need. For releases prior to Solaris 7, use named.boot, named.local, named.cache, named.mydomain, and named.mydomain.rev. For Solaris 7 and Solaris 8, the map files are the same, but edit the named.conf instead of named.boot.

3.Edit the /etc/resolv.conf file. It should look like the following:

domain mydomain.com
nameserver 127.0.0.1 ;if DNS server runs on this host
nameserver 129.200.9.1 ;if this is a remote client

4.Create a symbolic link in /etc/ to either the named.boot or named.conf file and start the DNS (/usr/sbin/in.named).

5.You can verify the DNS is working properly by running some queries to test forward and reverse resolution.

Full details are avalable here:

Thanks for you ut when i try to download this file and unpackage it i got that file is damaged

I need to know what the configuration i will edit in /etc/named.conf
# 4  
I just tried to download it now... It worked fine.
Try to download it again.

Here is the named.conf template file from the download.
Code:
//
//james liu 2/23/96
//revised 3/23/2000
//
//dns configuration file compatible with solaris 2.7 and later. This
//configuration is targeted at primary and secondary dns server setups.
//
//for solaris 2.6 and earlier, do not edit this file, but
//see the "named.boot" file for instructions.
//
//installation instructions:
//
//we assume you've unpacked this distribution.
//
//step 1;
//-------
//edit named.conf, named.local, named.cache, named.mydomain, and
//named.domain.rev and globally change all instances of "myhost" to
//the actual hostname, and "mydomain" to the desired domain name.
//also, change the ip numbers for the domain to match those for your
//network. for the reverse domain, just reverse the numbers for the
//class of address. this template is designed for a single class c.
//
//step 2:
//-------
//to use this, and create a symbolic link to this in /etc filesystem
//link to this file: ie:
//
//# ln -s [path-to-this]/named.conf /etc/named.conf
//
//step 3:
//-------
//start the dns server. /usr/sbin/in.named.
//
//
//
//for secondary domain name servers, use these entries; format is:
//<dns type> <domain> <prim. ip(s)> <filename>
//note, you can spec more than one prim. ip to download from
//in addition, the filename is the name to store the map in. you don't
//have to create this file. the common practice is to assign filenames
//as *.bak for files this server caches as a secondary dns relative to
//some other dns primary.
//
//almost all dns's can use themselves to resolve the local host
//you usually will leave this entry alone
//
//all dns's need to spec top-level cache servers that resolve world internet
//hostnames. there can be one or more entries and are spec'd in the cache
//file.
//
//if you are a subnet as a part of a larger network, (e.g. your domain is
//"mysubnet.mydomain.com", you may want to set forwarding to a higher
//level server (the one that serves names for "mydomain.com". if so,
//uncomment the 'forwarders' line below and edit it for your network
//parameters.
//

//specify the directory prefix where you plan to store the dns map files.
//the default here is /var/named.
options {
 	directory	 "/var/named";
//
//uncomment if you want to send queries outside of the primary to a
//a forwarders server.
//	forwarders       {
//		129.150.254.2;
//	};
};

//choose between primary or being a secondary server. a secondary dns is
//simply a server that downloads the dns maps from some other primary or
//secondary. the default here is to be a primary and have only one
//class c subnet. the dns needs a "forward map" that looks up ip address
//for a given hostname, and a "reverse map" that looks up hostname for
//a given ip address. if you have multiple subnets and domain name spaces,
//you should have multiple forward maps, and/or multiple reverse maps.
//in many networks, there is a single domain name space that spans several
//subnets, in which case, there will be one forward map, and many reverse
//maps.

zone "mydomain.com" in {
	type master;
	file "named.mydomain";
};

add more zones if you have multiple subnets as primary

zone "9.200.129.in-addr.arpa" in {
	type master;
	file "named.mydomain.rev";
};
//
//you can make this a secondary rather than primary by uncommenting
//these lines and commenting out the above primary zones and replacing
//with these below.  The masters IP address(es) are set to whatever your
//masters are.
//zone "mydomain.com" in {
//        type slave;
//        file "named.mydomain.bak";
//        masters { 129.200.9.1; 129.200.9.2 };
//};

//zone "9.200.129.in-addr.arpa" in {
//        type slave;
//        file "named.mydomain.9.bak";
//        masters { 129.200.9.1; 129.200.10.1 };
//};

//zone "10.200.129.in-addr.arpa" in {
//        type slave;
//        file "named.mydomain.10.bak";
//        masters { 129.200.10.1; 129.200.9.1 };
//};

// don't usually need to mess with this entry. You may need to edit
// the map file, named.local, however.
zone "0.0.127.in-addr.arpa" in {
	type master;
	file "named.local";
};

// nothing to do here.
zone "." in {
	type hint;
	file "named.cache";
};

//---------------end named.conf------------------

It looks like you have 192.168.11.36 in your /etc/resolv.conf file and 192.168.11.36 is not a DNS server, or it is a DNS server but you can't get to it from the server you are running nslookup on.

thanks for your reply

but how i can solve this issue

I configure /etc/named.conf
# The root nameservers
zone "." {
type hint;
file "db.rootcache";
};
# localhost - forward zone
zone "localhost" {
type master;
file "db.localhost";
notify no;
};
# localhost - inverse zone
zone "0.0.127.in-addr.arpa" {
type master;
file "db.127.0.0";
notify no;
};
zone "egynet.com.eg" { // Configure the domain cse.sc.edu
type master; // We are primary for it
file "egynet.com.eg";
allow-query { any; };
notify yes;

};
zone "11.168.192.in-addr.arpa" { // Configure the reverse zon
type master; // We are primary for it
file "11.168.192";
allow-query { any; };

};
