I m a new user of Linux. I installed RedHat 7.3

I have total 3 PC ....One redhat 7.2 , one redhat 7.3 and other is redhat 8..installed...I am trying to configure DNS at redhat 7.3 at pc2

I edit /etc/hosts file as :-

# Do not remove the following line, or various programs
# that require network functionality will fail.
# 127.0.0.1 pc1.com pc1 localhost.localdomain localhost
192.168.0.1 pc1 pc1.com
192.168.0.2 pc2 pc2.com
192.168.0.3 pc3 pc3.com
192.168.0.2 dns2

Then I edit /etc/named.conf file as :-

## named.conf - configuration for bind
#
# Generated automatically by bindconf, alchemist et al.
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};

include "/etc/rndc.key";

options {
directory "/var/named/";
};


zone "." {
type hint;
file "named.ca";
zone "pc2.com" IN {
type master;
file "pc2.zone";
};

Then I create pc2.zone file at /var/named/pc2.zone as :-

@ IN SOA dns2.pc2.com root.pc2.com. (
1 ; Serial
10800 ; refresh
3600 ; retry
604800 ; expire
86400 ; minimum
)
IN NS dns2.pc2.com
IN A 192.168.0.2
IN MX 5 dns2.pc2.com
Dns1 IN A 192.168.0.1
Dns1 IN MX dns1.pc1.com
;

www IN CNAME dns2
proxy IN CNAME dns2
mail IN CNAME dns2
smtp IN CNAME dns2

Then I create pc2.rev file at /var/named/pc2.rev file as :-

IN SOA dns2.pc2.com root.pc2.com. (
1 ; Serial
10800 ; refresh
3600 ; retry
604800 ; expire
86400 ; minimum
)
@ IN NS dns2.pc2.com
1 IN PTR dns2.pc2.com
2 IN PTR dns1.pc1.com

I still have the file localhost.zone at /var/named as :-

$TTL 86400
@ IN SOA @ root.localhost (
1 ; serial
28800 ; refresh
7200 ; retry
604800 ; expire
86400 ; ttl
)


@ IN NS localhost.


@ IN A 127.0.0.1

I have named.local file also at /var/named as :-

$TTL 86400
@ IN SOA localhost. root.localhost. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS localhost.

1 IN PTR localhost.

and also another file named.ca at /var/named directory.

Now when I type nslookup the prompt come ..
when I type "server" it says...

Default server: 192.168.0.2
Address: 192.168.0.2#53

What things I have to do more to complete DNS configuration..

Please help me.....

I am sorry...If I write too much...
actually I am trying to configure DNS for couple of days....
Can anybody suggest me "step by step" configuration ...pls..
I really need it...

Try this site http://www.tldp.org search for dns configuration.

It contains all stuff about linux, It is really a nice site to find an information, what ever it is, TLDP have it.

I'm trying to do the exact same thing. Have you tried typing:

"nslookup pc2.com"

What does it say? Does it spit out SERVFAIL? That's what mine does.

-twantrd

When I write "nslookup pc2.com"....

It says...

"Connection timed out; no servers could be reached"

Thanks,
