1. First you need to edit /etc/named.conf (e.g. sudo nano -w /etc/named.conf) and enter the following:
options {
directory "/var/named";
pid-file "/var/run/named/named.pid";
dump-file "data/cache_dump.db";
statistics-file "data/named_stats.txt";
memstatistics-file "data/named_mem_stats.txt";
forwarders {
4.2.2.1;
4.2.2.2;
};
listen-on port 53 { 127.0.0.1; 1.2.3.4; 5.6.7.8; };
listen-on-v6 port 53 { ::1; };
allow-query { 127.0.0.1; 64.6.231.1; 64.6.231.2; };
allow-recursion { 127.0.0.1; 64.6.231.1; 64.6.231.2; };
auth-nxdomain yes;
check-names master ignore;
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
channel log_zone_transfers {
file "/var/log/named/axfr.log";
print-time yes;
print-category yes;
print-severity yes;
};
category xfer-out { log_zone_transfers; };
category lame-servers { null; };
};
zone "." IN {
type hint;
file "named.ca";
};
include "/etc/named.rfc1912.zones";
zone "domain.com" {
type master;
file "/var/named/.com.db";
allow-query { any; };
allow-update { key "rndckey"; };
};
key "rndckey" {
algorithm hmac-md5;
secret "+z2YW71pGwapo6A2Ko5/xQ==";
};
controls {
inet 127.0.0.1 allow { localhost; } keys { "rndckey"; };
};
where,
- 1.2.3.4 and 5.6.7.8 are the IP addresses of the network interfaces of the server (issue the command ifconfig at the prompt to see them);
- domain.com is the name of the domain (replace it with your domain).
- the rndckey entry was generated using the command rndc-confgen (you should also create the file /etc/rndc.conf with entries specified in the rndc-confgen command output); and
- 4.2.2.1 and 4.2.2.2 are publicly available name servers we used as forwarders (i.e., if our name server cannot answer a DNS query, it will be forwarded to these name servers.
2. Now, create the file /var/named/domain.com.db (e.g. sudo nano -w
/var/named/domain.com.db) and enter the following:
$TTL 86400
domain.com. 86400 IN SOA ns1.domain.com. me.domain.com. (
2010091401 ;Serial Number
7200 ;refresh
1800 ;retry
2419200 ;expire
86400 ;minimum
)
$TTL 259200
domain.com. 259200 IN NS ns1.domain.com.
domain.com. 259200 IN NS ns2.domain.com.
$TTL 86400
domain.com. 86400 IN A 1.2.3.4
domain.com. 86400 IN MX 0 mail.domain.com.
$TTL 86400
mail 86400 IN A 1.2.3.4
ns1 86400 IN A 1.2.3.4
ns2 86400 IN A 5.6.7.8
www 86400 IN A 1.2.3.4
3. Finally, restart the BIND name server (i.e., sudo /etc/rc.d/init.d/named restart). At this point, you should have set the name servers (ns1.domain.com and ns2.domain.com) for your domain (domain.com) at your domain registrar.
