    Many conventional Unix server settings files get rewritten by MacOS X on boot, or on system updates. Plus its not as hard to define forwarders as the above suggests.

    • Launch Server.app.
    • Select DNS and turn if on if not already.
    • Probably want to select "Perform lookups for all clients"
    • Under the on/off button is Settings, click the "Edit…" button.
    • Forwarding Servers dialog box pops up. Click the plus sign to add one. Click it again to add another.
    • Click OK and its all done.

    Hey dkelly,

     Totally true, also the BIND for the server on the ETC folders corrupt the network plist files and shutdown the IPV4 and Subnet Mask from being changed so the computer looses Dynamic (not that you want that on the server).

     

     

    Thanks! Tested and worked! 

     

    Cheers!

    Hi all, 

     

    Any thoughts on how to configure openDNS forwarding on Open Directory Server running on 10.11.5? 

    I  edit forwarding servers  -> + -> 208.67.222.222 -> + 208.67.220.220 
    Restarted the server and the computer it was running on. I did this on both our primary and secondary servers. Still no connection. 

     

    Next, I tried flushing the DNS cache on both our primary and secondary DNS servers from terminal following the commands in this article : http://www.howtoisolve.com/how-to-flush-dns-cache-in-mac-os-x-ei-capitan-10-11-10-10-4/

     

    1. sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder;say flushed

    2.sudo killall -HUP mDNSResponder

     


    I then manually restarted both our primary and secondary servers again and still DNS forwarding is not working? Have other folks had this problem? 

    Or perhaps a solution to it? 

     

    Thanks,

    Did you see any instruction to also add the Google resolvers as forwarders?  If not, why do you do it nevertheless?

    Rotblitz,

    The instructions do not specify, that forwarding to additional resolvers such as google will make or breath openDNS functionality in this type of configuration.  The benefits of google's public dns is that it speeds up browsing.  https://developers.google.com/speed/public-dns/ 

    As is such it is included in some configuration guides.

     

    That said I now realize that openDNS only works when its servers are the only entries in the forwarding configuration on Mac OS open directory server running El Cap 10.11.5.

    Just because instructions for something don't say not to do additional things doesn't mean that adding completely different things won't have negative impacts.

    Also, OpenDNS only works as expected when it is the only resolvers used. It doesn't matter what OS, router, or anything else you are using. If you are configured to use other DNS servers then it's guaranteed that some or all of your traffic will got to servers other than OpenDNS, meaning OpenDNS can't do what it's intended to do.
