Hi All:
For whatever reason I can not get dns caching to work on any of my
centos boxes. Running Centos 5 and 6. Any thoughts on why these will
not run? The services start fine but when telling to perform a dig
using itself as the resolver the queries fail (See below).
Any help would be appreciated.
Thanks,
Ed
