configuration for afraid-dyndns on Fedora and other similar distro.

First install afraid-dyndns with the command:

  <td>

      sudo yum install afraid-dyndns
    </div>
  </td>
</tr>

Now open the configuration file /etc/afraid-dyndns.cfg and we need to change the following:

Notify = root@localhost # leave empty to suppress notifications

open (OUT_FILE, &#8221;>test.csv&#8221;);
