Command Line Configuration
If you want to customize DNS Manager to meet your requirements, you can use the command line utilities included in the software distribution. This way you can configure the low level engine and the DNS Manager interface.
Low Level Engine Configuration
The file /etc/dnsmanager/dnsmanager.conf contains several directives which control the DNS Manager low level behavior. These directives cannot be modified using the browser interface. You should only modify them if you fully understand their functionality.
""
These values are modified during the product installation based on admin input. If you change these values, you might experience problems.
