What are the IP requirements for DirectAdmin to run?
In order for DirectAdmin to be able to run on your system, 3 things must be true:
The licensed IP must exists on the box. Type /sbin/ifconfig, and you must see the licensed IP in the output.
The licensed IP must function and be able to be bound to, eg:
wget --bind-address=220.127.116.11 http://www.directadmin.com/index.html
