Setup "master2slave" script for DirectAdmin plus ASSP (Spam Proxy) on two machines.

Hi .. I have 3 CentOS5.3 64Bit servers. One is running the DirectAdmin control panel. I want the other two machine to run as an automated secondary DNS using this script - [login to view URL];highlight=master2slave I also want to do some spam filtering on these boxes .. I have ASSP Spam Proxy running on one, and it's running ok under a test. I need ti setup at a service to auto run in the background. Need it all tested, with minimal downtime. If all goes well, more work will definitely be pending. Cheers,
