Bind9 is the core software component for DNS services. To install Bind9, run the following command:
$ sudo apt install bind9
Step 3: Install OpenSSL
OpenSSL is required for securing DNS communications. Install OpenSSL by executing:
$ sudo apt install openssl
Step 4: Configure Bind9
Now it’s time to configure Bind9 for SlowDNS. Open the main configuration file using a text editor:
$ sudo nano /etc/bind/named.conf.options
Add the following lines to the options block:
...
options {
directory "/var/cache/bind";
recursion yes;
allow-recursion { trusted; };
listen-on { any; };
listen-on-v6 { any; };
forwarders {
8.8.8.8;
8.8.4.4;
};
dnssec-validation auto;
auth-nxdomain no;
...
}
...
Save the changes and exit the text editor.
Step 5: Create the Zone Files
Zone files contain the DNS records for your website. In this step, we will create two zone files: one for the domain and another for reverse DNS lookup. Create the domain zone file:
$ sudo nano /etc/bind/zones/db.yourdomain.com
Add the following content to the file:
$ORIGIN .
$TTL 86400 ; 1 day
yourdomain.com IN SOA ns1.yourdomain.com. admin.yourdomain.com. (
2022010101 ; serial
3600 ; refresh (1 hour)
1800 ; retry (30 minutes)
604800 ; expire (1 week)
86400 ; minimum (1 day)
)
...
Save the file and exit the text editor. Repeat the same steps to create the reverse DNS zone file:
$ sudo nano /etc/bind/zones/db.0.0.127.in-addr.arpa
Add the following content to the file:
$ORIGIN .
$TTL 86400 ; 1 day
0.0.127.in-addr.arpa IN SOA ns1.yourdomain.com. admin.yourdomain.com. (
2022010101 ; serial
3600 ; refresh (1 hour)
1800 ; retry (30 minutes)
604800 ; expire (1 week)
86400 ; minimum (1 day)
)
...
Save the file and exit the text editor.
Step 6: Test Bind9 Configuration
Before starting the service, it is important to verify the configuration. Run the following command:
$ sudo named-checkconf
If the output shows no errors, proceed to start the service:
$ sudo systemctl start bind9
To enable the service to start on boot, run:
$ sudo systemctl enable bind9
With these steps completed, you have successfully installed and set up SlowDNS on your server. In the next sections, we will explore advanced configurations and customization options to optimize your SlowDNS for SEO and ranking purposes.
Configuration and Customization
SlowDNS offers several advanced configuration options and customization capabilities, allowing you to tailor the DNS infrastructure to your specific needs. Let’s explore some key aspects of SlowDNS configuration:
1. DNS Caching
DNS caching improves response times and reduces the load on authoritative DNS servers. By enabling caching in SlowDNS, you can store the resolved DNS queries locally for a specified time period. To enable DNS caching, add the following lines to the named.conf.options file:
...
options {
directory "/var/cache/bind";
recursion yes;
allow-recursion { trusted; };
listen-on { any; };
listen-on-v6 { any; };
forwarders {
8.8.8.8;
8.8.4.4;
};
dnssec-validation auto;
auth-nxdomain no;
// Enable DNS caching
max-cache-size 10m;
max-ncache-ttl 7200;
max-cache-ttl 7200;
...
}
...
Save the file and restart the SlowDNS service:
$ sudo systemctl restart bind9
2. Load Balancing
SlowDNS allows you to distribute incoming DNS queries across multiple servers, ensuring high availability and improved performance. To configure load balancing, you can define multiple A (Address) records in the zone file, each pointing to a different server:
$ORIGIN .
$TTL 86400 ; 1 day
yourdomain.com IN SOA ns1.yourdomain.com. admin.yourdomain.com. (
2022010101 ; serial
3600 ; refresh (1 hour)
1800 ; retry (30 minutes)
604800 ; expire (1 week)
86400 ; minimum (1 day)
)
yourdomain.com IN A 192.168.1.100
IN A 192.168.1.101
IN A 192.168.1.102
...
...
Ensure that the A records point to valid IP addresses of your DNS servers. Save the zone file and restart SlowDNS for changes to take effect.
3. Traffic Routing with DNS Views
SlowDNS supports DNS views, allowing you to present different DNS responses based on defined criteria such as source IP address or subnet. This feature enables you to implement traffic routing and serve customized DNS records. To configure DNS views, make the following changes in named.conf.options:
...
options {
directory "/var/cache/bind";
recursion yes;
allow-recursion { trusted; };
listen-on { any; };
listen-on-v6 { any; };
forwarders {
8.8.8.8;
8.8.4.4;
};
dnssec-validation auto;
auth-nxdomain no;
// Configure DNS Views
view "internal" {
match-clients { 192.168.1.0/24; };
allow-recursion { localnets; };
zone "yourdomain.com" {
type master;
file "/etc/bind/zones/db.yourdomain.internal";
};
// Additional views...
};
...
}
...
Create the zone file for the internal view:
$ sudo nano /etc/bind/zones/db.yourdomain.internal
Add the necessary DNS records for the internal view:
$ORIGIN .
$TTL 86400 ; 1 day
yourdomain.com IN SOA ns1.yourdomain.com. admin.yourdomain.com. (
2022010101 ; serial
3600 ; refresh (1 hour)
1800 ; retry (30 minutes)
604800 ; expire (1 week)
86400 ; minimum (1 day)
)
...
Save the file and restart SlowDNS. Now, DNS requests from the defined IP range will be handled by the internal view, allowing you to serve specific DNS responses.
4. DNSSEC (Domain Name System Security Extensions)
DNSSEC adds an additional layer of security to DNS, protecting against various attacks and ensuring the authenticity of DNS data. SlowDNS supports DNSSEC, and you can enable it by modifying the named.conf.options file as follows:
...
options {
directory "/var/cache/bind";
recursion yes;
allow-recursion { trusted; };
listen-on { any; };
listen-on-v6 { any; };
forwarders {
8.8.8.8;
8.8.4.4;
};
// Enable DNSSEC
dnssec-validation yes;
dnssec-enable yes;
dnssec-lookaside auto;
auth-nxdomain no;
...
}
...
Save the file and restart SlowDNS for the changes to take effect. Don’t forget to sign your DNS zone files with appropriate DNSSEC signatures.
These are just a few examples of the extensive customization capabilities provided by SlowDNS. Feel free to explore the official documentation and experiment with more advanced configurations to meet your specific requirements.
