For PowerDNS 4.0>

Requirements:

• Server with installed OS such as Cnet OS
• PowerDNS has been set and work properly

There is a video for this process.

Here is the process:

1. Login to your DNS server using superuser as root.

2. Launch the terminal. If you don’t log in as superuser, then type:

$ su –

3. Check the version number of PowerDNS by using one of the two commands below.

Note: Only version 4.0 and above support CAA records.

a)

# Dig chaos txt version.bind @yourip+short

b)

#pdns_server --version

4. Review your zone file entries by entering the command below:

#Pdnsutil list-zone <your zone file>



5. To edit the zone file, enter the command shown here:

#pdns edit-zone <your zone file>

6. Place the cursor on the bottom of the entries and hit the Enter button to add a new line.

7. Type the following line to your zone for adding CAA record for Entrust:

For Entrust:

Yourdomain       IN       CAA       0 issue "entrust.net"

For D-Trust

Yourdomain       IN       CAA       0 issue "d-trust.net"

(*seven spaces between first three character sets)

NOTE: yourdomain is your domain name that is listed on your SOA

In the example below, the SOA is using entrustcertlab.com, hence the line to be added will be:

entrustcertlab.comINCAA0 issue “entrust.net”



8. Save the modification and exit to the file editor.

NOTE:

If your organization currently uses “entrust.net” for your CAA record, we recommend adding a separate CAA record for D-Trust.

9. At this point, the CAA record has been added to your zone file, and you can restart your service by typing:

# service pdns restart
