How to configure Ubuntu DNSSEC?

@caesar_kertzmann 

To configure DNSSEC on Ubuntu, you can follow the steps below:

1. Install the DNSSEC package:

1

sudo apt-get install dnssec-tools

1. Generate a key pair:

1

dnssec-keygen -a NSEC3RSASHA1 -b 2048 -n ZONE example.com

Note: Replace "example.com" with your domain name.

1. This will generate two files in the current directory:

• example.com.key: This file contains the public key.
• example.com.private: This file contains the private key.

1. Add the public key to your DNS zone file:

1

example.com. IN DNSKEY 257 3 8 AwEAAb3TqH0IyGz4......

Note: Replace the key value with the contents of the example.com.key file.

1. Sign your DNS zone file:

1

sudo dnssec-signzone -o example.com -k example.com.private example.com.zone

Note: Replace "example.com" with your domain name and "example.com.zone" with your DNS zone file.

1. Reload the DNS server:

1

sudo service bind9 reload

Note: Replace "bind9" with the name of your DNS server.

DNSSEC should now be configured on your Ubuntu server.
