How do I disable recursive DNS queries on my Linux server with Parallels Plesk Panel?

For information on recursive DNS, see What risks are associated with recursive DNS queries?.

To Disable Recursive DNS

1. Log in to Parallels Plesk Panel as "admin".
2. On the left hand side under the System Group click Server.
3. In the main panel under the Services heading select DNS Settings.
4. Under the Tools heading click Localnets.
5. Place the dot next to the Allow for local requests only.
6. Click the Ok button.

If you do not have this option in Parallels Plesk Panel you will need to perform this update using the following commands:

1. Using SSH, log in to your server with the User ID and Password that you created when you set up your dedicated hosting account.
2. At the command line, type the following and press Enter.
   
   su -
   
3. Type the following three commands and press Enter after each.
   
   cd /tmp/
   
   
   wget -O rdnsfix http://products.secureserver.net/scripts/rdnsfix
   
   
   php -c /r rdnsfix
