Kaj naj ti recem? Nastaviti moras split view.

Evo en link kako to uredit:

      Example named.conf

// This is the primary configuration file for the BIND DNS server named.
// This is for example only

acl "dns_slaves" {
	172.16.1.2;				# IP of the slave DNS nameserver
	172.16.101.2				# ditto
};

acl "lan_hosts" {
	192.168.0.0/24;				# network address of your local LAN
	127.0.0.1;				# allow loop back
};

options {					# this section sets the default options
	directory "/etc/namedb"			# directory where the zone files will reside
	listen-on {
		192.168.0.1;			# IP address of the local interface to listen
		127.0.0.1;			# ditto
	};
	auth-nxdomain no;			# conform to RFC1035
	allow-query { any; };			# allow anyone to issue queries
	recursion no;				# disallow recursive queries unless over-ridden below
	version "0";				# obscures version reporting - can't hurt
};

key "rndc-key" {
        algorithm hmac-md5;
        secret "nOzUd7+Hwdq6k6CQq7SbDw==";	# DO NOT USE THIS KEY - example only
};

controls {
        inet 127.0.0.1 allow { localhost; }
        keys { rndc-key; };
};

view "internal" {
        match-clients { lan_hosts; };		# match hosts in acl "lan_hosts" above
        recursion yes;				# allow recursive queries
        notify no;				# disable AA notifies

        // prime the server with knowledge of the root servers
        zone "." {
                type hint;
                file "db.root";
        };
        // be authoritative for the localhost forward and reverse zones, and for
        // broadcast zones as per RFC 1912
        zone "localhost" {
                type master;
                file "db.local";

        };
};

view "external" {

	// "localnets" and "any" are special reserved words
	// "localnets" mean any network address (as opposed to host address) configured
	// on the local network interfaces - "!" means to negate
        match-clients { !localnets; any; };
        recursion no;			# disallow recursive queries
        allow-transfer { dns_slaves; };	# allow "hosts in act "dns_slaves" to transfer zones

        zone "example.com" {

        };
};
