Root Server Simulation Communication Problem

[Ben Bridges]

You have recursion disabled on your abc.com server, and I believe that
is preventing your query from succeeding.  My understanding is that the
contents of the root hints file are not stored in the server's cache
(which means, I think, that they are not themselves returned in response
to queries for those records).  Since you have recursion disabled on
abc.com, it is never using its root hints to query your root server
(rootns.man) for the NS and A records for the root zone (which sounds
obfuscated, but it is done that way because the root servers themselves
have the most current list of servers for the root zone).

Subject: Root Server Simulation Communication Problem



	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
