    Hi All,

    I recently ran some of my websites on my ISPconfig server (Fedora Cora 4) through, and saw one glaring error: "Open DNS Servers".

    Essentially closing DNS servers prevents "recursion".

    I'm not 100% on what this means, but all I can say is that I found a pretty good - and simple - way to close your servers:;)

    It takes about 10 mins at most of configuration and troubleshooting. Be careful with DNS, the slightest error can cause it to not function.

    Hopefully this is compatible with all ISPconfig releases...:D

    allow-recursion {
    3) restart named
