After looking on Ubuntu forum for an easy step-by-step howto for instaling a DNS server, I decided the best idea would probably be to write this howto myself.... So, here it is!
Step 1: Install Ubuntu dapper, or use your WORKING installation.
Step2: Install bind 9:
Step 3: Configure the main Bind files. Usually, if you install Bind from the source code, you will have to edit the file named.conf. However, Ubuntu provides you with a pre-configured Bind, so we will edit another file:
This is where we will insert our zones. By the way, a zone is a domain name that is referenced in the DNS server
Insert this in the named.conf.local file:
Ok, now, let's edit the options file:
We need to modify the forwarder. This is the DNS server to which your own DNS will forward the requests he cannot process.
Now, let's add the zone definition files (replace example.com with your domain name:
The zone definition file is where we will put all the addresses / machine names that our DNS server will know. You can take the following example:
Now, let's create the reverse DNS zone file:
Copy and paste the following text, modify as needed:
Ok, now you just need to restart bind:
We can now test the new DNS server...
Step 4: Modify the file resolv.conf with the following settings:
enter the following:
Now, test your DNS:
Look at the result.... Enjoy!
Step 1: Install Ubuntu dapper, or use your WORKING installation.
Step2: Install bind 9:
Code:
sudo apt-get install bind9
Code:
sudo vi /etc/bind/named.conf.local
Insert this in the named.conf.local file:
Code:
# This is the zone definition. replace example.com with your domain name zone "example.com" { type master; file "/etc/bind/zones/example.com.db"; }; # This is the zone definition for reverse DNS. replace 0.168.192 with your network address in reverse notation - e.g my network address is 192.168.0 zone "0.168.192.in-addr.arpa" { type master; file "/etc/bind/zones/rev.0.168.192.in-addr.arpa"; };
Code:
sudo vi /etc/bind/named.conf.options
Code:
forwarders { # Replace the address below with the address of your provider's DNS server 123.123.123.123; };
Code:
sudo mkdir /etc/bind/zones sudo vi /etc/bind/zones/example.com.db
Code:
// replace example.com with your domain name. do not forget the . after the domain name! // Also, replace ns1 with the name of your DNS server example.com. IN SOA ns1.example.com. admin.example.com. ( // Do not modify the following lines! 2006081401 28800 3600 604800 38400 ) // Replace the following line as necessary: // ns1 = DNS Server name // mta = mail server name // example.com = domain name example.com. IN NS ns1.example.com. example.com. IN MX 10 mta.example.com. // Replace the IP address with the right IP addresses. www IN A 192.168.0.2 mta IN A 192.168.0.3 ns1 IN A 192.168.0.1
Code:
sudo vi /etc/bind/zones/rev.0.168.192.in-addr.arpa
Code:
//replace example.com with yoour domain name, ns1 with your DNS server name. // The number before IN PTR example.com is the machine address of the DNS server. in my case, it's 1, as my IP address is 192.168.0.1. @ IN SOA ns1.example.com. admin.example.com. ( 2006081401; 28800; 604800; 604800; 86400 ) IN NS ns1.example.com. 1 IN PTR example.com
Code:
sudo /etc/init.d/bind9 restart
Step 4: Modify the file resolv.conf with the following settings:
Code:
sudo vi /etc/resolv.conf
Code:
// replace example.com with your domain name, and 192.168.0.1 with the address of your new DNS server. search example.com nameserver 192.168.0.1
Code:
dig example.com
