awmn public caching DNS and reverse zone authoriative server on debian

This is a quick and dirty recipe of how to set up a public caching and authoritative for a reverse zone nameserver for the Athens Wireless Metropolitan Network and the other Greek Wireless Communities on a debian based system.

Install bind 
# apt-get install bind


Put the following on /etc/bind/named.conf 
# cat /etc/bind/named.conf
//#g0 - 2012 

include "/etc/bind/named.conf.options";
include "/etc/bind/named.conf.local";


Put the following on /etc/bind/named.conf.options
and replace 10.27.224.17 with your IP address. 
# cat /etc/bind/named.conf.options 
options {
 directory "/var/cache/bind";

 version "awmn. #g0 2012 alog.ipduh.com";

        listen-on { 127.0.0.1; 10.27.224.17; };

 auth-nxdomain no;    # conform to RFC1035
};


Put something like the following in /etc/bind/named.conf.local
Replace 224.27.10.in-addr.arpa with your reverse DNS zone 
# cat named.conf.local 
//g0 2012 http://ipduh.com/contact

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";
acl internals {
        127.0.0.0/8;
 10.0.0.0/8;
};

view "internal" {
        match-clients { internals; };
        recursion yes;
        allow-recursion { any; };
        allow-query { any; };
        allow-query-cache { any; };

// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912

zone "localhost" {
        type master;
        file "/etc/bind/db.local";
};

zone "127.in-addr.arpa" {
        type master;
        file "/etc/bind/db.127";
};

zone "0.in-addr.arpa" {
        type master;
        file "/etc/bind/db.0";
};

zone "255.in-addr.arpa" {
        type master;
        file "/etc/bind/db.255";
};

//10.27.224.0/24 reverse zone 
zone "224.27.10.in-addr.arpa" IN {
        type master;
        file "/var/cache/bind/db.224.27.10.in-addr.arpa";
        allow-update { none; };
};

zone "10.in-addr.arpa" IN {

        forwarders {

          10.19.143.12;
          //10.19.143.13;
        };
};

Then put the zone info for 224.27.10.in-addr.arpa ( our example reverse zone ) at /var/cache/bind/db.224.27.10.in-addr.arpa or another appropriately named file 

# cat /var/cache/bind/db.224.27.10.in-addr.arpa
$ORIGIN 224.27.10.in-addr.arpa.
$TTL 86400
@ IN SOA ns1.geioa.ns.awmn. systems-awmn.bot.ipduh.com. (
                    2012122501 ; serial
                    21600      ; refresh after 6 hours
                    3600       ; retry after 1 hour
                    604800     ; expire after 1 week
                    86400 )    ; minimum TTL of 1 day

          IN  NS ns1.geioa.ns.awmn.

1          IN  PTR router.geioa.ns.awmn.
17         IN  PTR serverakos.geioa.ns.awmn.


Then restart bind 
# /etc/init.d/bind9 restart
