=Installation af DNS=

Instructions

==Install DNS sserver software==

sudo apt-get install bind9

==configure DNS (Bind)==
We need to touch 5 files.

We will edit 3 files.
#/etc/bind/named.conf.local
#/etc/bind/named.conf.options
#/etc/resolv.conf

We will create 2 files.
#/etc/bind/zones/mydomain.com.db
#/etc/bind/zones/rev.0.168.192.in-addr.arpa

===First step: add domain zone – mydomain.com===

*sudo vi /etc/bind/named.conf.local
<source lang=cli>
# Our domain zone
zone "mydomain.com" {
type master;
file "/etc/bind/zones/mydomain.com.db";
}

# For reverse DNS
zone "0.168.192.in-addr.arpa" {
type master;
file "/etc/bind/zones/rev.0.168.192.in-addr.arpa";
}

</source>

We just created a new domain. Please note: later we will create two files named mydomain.com.db and rev.0.168.192.in-addr.arpa files. Also, notice the reverse IP address sequence in the reverse DNS section.

# Let’s add the DNS servers from your ISP. In my case, I’m using Comcast DNS servers. You can place the primary and secondary DNS servers here separated by semicolons.

sudo vi /etc/bind/named.conf.options

forwarders {
68.87.76.178;
};
Save file. Exit.

# Now, let’s modify the resolv.conf file found in /etc and place the IP address of our DNS server which is set to 192.168.0.9.

$ sudo vi /etc/resolv.conf
