[Tutorial] Instalarea si configurarea unui Server DNS

[FeNNix]

Pasul 1

Instalam bind9

# apt-get install bind9 dnsutils
# /etc/init.d/bind9 stop

Pasul 2

In directorul /etc/bind vom configura urmatoarele fisiere si vom creea un director zones unde vom pune fisierele db.slashlinux.info sidb.192 .

# nano /etc/bind/named.conf.local

named.conf.local

zone "slashlinux.info" {

type master;

file "/etc/bind/zones/db.slashlinux.info";

};

zone "0.168.192.in-addr.arpa" {

type master;

file "/etc/bind/zones/db.192";

};

# nano /etc/bind/named.conf.option

s

named.conf.options

forwarders {

0.0.0.0; ## IP-ul ISP-ului vostru

};

# mkdir /etc/bind/zones
# nano /etc/bind/zones/db.slashlinux.info

db.slashlinux.info

$TTL 86400
  $ORIGIN info.
  slashlinux	  IN	  SOA	 ns1.slashlinux.info. root.slashlinux.info.(

  $ORIGIN slashlinux.info.

  mail			IN	  A	   192.168.0.1
  ns1			 IN	  A	   192.168.0.1
  root			IN	  A	   192.168.0.1

# nano /etc/bind/zones/db.192

db.192

  $TTL 86400
  $ORIGIN info.
  slashlinux	  IN	  SOA	 ns1.slashlinux.info. root.slashlinux.info.(

		  IN	  A			   192.168.0.1

  $ORIGIN slashlinux.info.
  www			 IN	  A	   192.168.0.1
  mail			IN	  A	   192.168.0.1
  ns1			 IN	  A	   192.168.0.1
  root			IN	  A	   192.168.0.1

Pasul 3

Restartam bind9 si verificam cu comanda dig.

# /etc/init.d/bind9 start
# rndc reload
# dig slashlinux.info

output-ul comenzii dig
