Root Server Simulation Communication Problem

[T MANIKANDAN-PKXR74]

Hi,

  I am trying to set up lab which replicates the root server also. ( DNS
with Root server simulation for Intranet),
Basically I have two servers one abc.com as authoritative server and the
other rootns.man acting as root server. running BIND 9 on both. 


 I have done the following things in my named.conf file

options {
directory "/var/named";
recursion no;
};

zone "." {
type hint;
file "root";
};

zone "abc.com" IN {
type master;
file "forward";
};

zone "10.168.192.in-addr.arpa" IN {
type master;
file "reverse";
};

My root File (Points to another DNS acting as Root server let us call
rootns.man)

.               86400           IN      NS      rootns.man.
rootns.man.     86400           IN      A       1.2.3.4

My Forward and reverse file

$TTL 3600
@ IN SOA abc.com. root.abc.com. (
                                42      ; serial
                                3H      ; refresh
                                15M     ; retry
                                1W      ; expiry
                                1D)     ; minimum
                IN NS abc.com.
abc.com. IN A 192.168.10.12


$TTL 3600
@ IN SOA abc.com. root.abc.com.(
                                42      ; serial
                                3H      ; refresh
                                15M     ; retry
                                1W      ; expiry
                                1D)     ; minimum

 IN NS abc.com.
12 IN PTR abc.com.

In the other DNS server rootns.man (acting root server)

zone "." IN {
type master;
file "forward";
};


Forward file in roons.man server


$TTL    86400
@               IN SOA  rootns.man root.rootns.man (
                                        42              ; serial (d.
adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum
.               IN NS           rootns.man.
rootns.man.     IN A            1.2.3.4 

 

Once completing this I have a minor problem that is my abc.com server is
not able to determine the root server (rootns.man) IP address. attached
the DIG output from abc.com server. can any one please help me in
resolving this issue.

 

Regards

Mani
