i'ts not much. it's around 40 users.
--------------------------------------------------------------------------------
problems:
when restart bind service error.
p { margin-bottom: 0.08in; } * stopping domain name service... bind9 rndc: connection remote host closed
this may indicate
* remote server using older version of command protocol,
* host not authorized connect,
* clocks not synchronized, or
* key invalid. [ ok ]
* starting domain name service... bind9 [ fail ]

this named.conf:
p { margin-bottom: 0.08in; } named.conf
// primary configuration file bind dns server named.
//
// please read /usr/share/doc/bind9/readme.debian.gz information on
// structure of bind configuration files in debian, *before* customize
// configuration file.
//
// if adding zones, please in /etc/bind/named.conf.local


controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "rndc-key"; };
};


include "/etc/bind/named.conf.options";
include "/etc/bind/named.conf.local";
include "/etc/bind/named.conf.default-zones";

my named.conf.options
p { margin-bottom: 0.08in; } named.conf.options
//----------------------
options {
directory "/var/cache/bind";


// if there firewall between , nameservers want
// talk to, may need fix firewall allow multiple
// ports talk. see http://www.kb.cert.org/vuls/id/800113


// if isp provided 1 or more ip addresses stable

auth-nxdomain no; # conform rfc1035

forwarders {
# replace address below address of provider’s dns server
8.8.8.8;
};

my example.com.db
p { margin-bottom: 0.08in; }

//------------------
// replace example.com domain name.


example.com. in soa ns1.example.com. admin.example.com.
(
// not modify following lines!

)


// replace following line necessary:
// ns1 = dns server name
// mail = mail server name
// example.com = domain name
example.com. in ns ns1.example.com.
example.com. in mx 10 mail.example.com.


// replace ip address right ip addresses.
www in 192.168.1.120
mta in 192.168.1.121
ns1 in 192.168.1.122
