MyDNS is a DNS server for UNIX that serves records directly from an SQL database and can be used in H-Sphere as an alternative to bind. Currently H-Sphere supports MyDNS to work with MySQL DB only. To configure H-Sphere to work with MyDNS, follow the instrcutions below:

1. Download the latest version of MyDNS from http://mydns.bboy.net.
2. Install and configure MyDNS version that is served by MySQL DB on a new or any of your existing H-Sphere servers following the instructions that come with the installation package.
   Warning: do not rename the 'mydns' MySQL DB created during the installtaion.
3. Configure H-Sphere to work with MyDNS.

3.1. Add the following lines into the ~cpanel/psoft_config/hsphere_properties file:

MYDNS_USER = login
MYDNS_PASS = password
MYDNS_DB_HOST = IP

where:

login is the name of MyDNS user to access MySQL DB you've created during the installation procedure;
password is the password you've entered during the installation procedure for MyDNS user login;
IP is the IP address of the server with MySQL DB created during the installation procedure.

3.2. In admin control panel check if MyDNS name server is listed as a server group. If it's not, connect to hsphere database and execute:

INSERT INTO l_server_groups(id,type_id,name)
VALUES(21,2,'MyDNS name server');

3.3. Restart your CP.
3.4. If you install MyDNS on a new server, add this physical server.
3.5. Add MyDNS logical server(s) with the MyDNS name server group and check if it is available for signup.
