Build a DNS server in Ubuntu 14.04
I want to test a device DNS feature, so I build a DNS server in my Ubuntu PC.
In this example, I want to my device to send the report to report.com which is a specail PC, and the PC IP address is 192.168.1.15
Note that, the configuration needs root.
install bind9.
apt-get install bind9
1. modify /etc/bind/name.conf.local
add below content
zone "report.com"{
type master;
file "db.report.com";
};
2. copy the file /etc/bind/db.local to /var/cache/bind/db.report.com
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA report.com. root.report.com. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS localhost.
@ IN A 127.0.0.1
@ IN AAAA ::1
@ IN A 10.10.3.154
4. edit the file : /etc/bind/named.conf.options
options {
directory "/var/cache/bind";
// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk. See http://www.kb.cert.org/vuls/id/800113
// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0‘s placeholder.
// forwarders {
// 0.0.0.0;
// };
forwarders {
8.8.8.8;
};
//========================================================================
// If BIND logs error messages about the root key being expired,
// you will need to update your keys. See https://www.isc.org/bind-keys
//========================================================================
dnssec-validation auto;
auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };
};
3. /etc/init.d/bind9 restart
4. test: ping report.com
