hi, thank you for your replied..

I want to setup for our local project only which is for LAN network only.. which other pc can look at my server and other machines/servers can look to this server or reversable.. can you guide me on how to setup this? I have named.conf installed on my server.. sorry I'm quite new to this, I have looked through the document or articles on internet but somehow its quite confusing.. maybe this will be a good start for others as well.. I will post this to my blog to teach other persons when I able to set this by myself..

once again thank you for your response and help for me.. appreciate it!!!

hi, btw this is my /etc/named.conf file.. what I do really want is other servers or pc's can look to this server.. or this server can look to other servers.. lets say I name my server trial1, trial2, trial3, trial4.. I want them can look or resolve each other if it's possible. I guess 1 server must be a master while the rest are slaves

Code:
//
// named.conf for Red Hat caching-nameserver 
//
 
options {
    directory "/var/named";
    dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
    /*
     * If there is a firewall between you and nameservers you want
     * to talk to, you might need to uncomment the query-source
     * directive below. Previous versions of BIND always asked
     * questions using port 53, but BIND 8.1 uses an unprivileged
     * port by default.
     */
     // query-source address * port 53;
};
 
// 
// a caching only nameserver config
// 
controls {
    inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
 
zone "." IN {
    type hint;
    file "named.ca";
};
 
zone "localdomain" IN {
    type master;
    file "localdomain.zone";
    allow-update { none; };
};
 
zone "localhost" IN {
    type master;
    file "localhost.zone";
    allow-update { none; };
};
 
zone "0.0.127.in-addr.arpa" IN {
    type master;
    file "named.local";
    allow-update { none; };
};
 
zone "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {
type master;
    file "named.ip6.local";
    allow-update { none; };
};
 
zone "255.in-addr.arpa" IN {
    type master;
    file "named.broadcast";
    allow-update { none; };
};
 
zone "0.in-addr.arpa" IN {
    type master;
    file "named.zero";
    allow-update { none; };
};
 
include "/etc/rndc.key";

lets say the name of this server is trial1, I tried to do nslookup from this trial1 server whether it will give a response.. below is my config and details
Code:
#/etc/init.d/named start [ok]

#ps -ef | grep named
named 19510 1 0 10:42 ? 00:00:02 /usr/sbin/named -u named -t /var/named/chroot

#cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.20.21 trial1

#cat /etc/resolv.conf
search trial1
nameserver 192.168.20.21

#nslookup trial1
Server: 192.168.20.21
Address: 192.168.20.21#53

** server can't find trial1: SERVFAIL

---------------------------------------

---------- Post updated at 05:35 PM ---------- Previous update was at 01:28 PM ----------

I have modified the zone and somehow able to nslookup my trial1 server.. I name the trial1 server as server.trial1.com
and I changed the zone name to server.trial1.com and modified the ipaddress inside..

the question is.. if I am using the other servers lets say TRIAL2, how can I make this trial2 to nslookup trial1?
because I tried that but it was not able to.. sigh* I have no one to guide me through this Smilie
