    Yes, I know lots of places don't have DNSSEC signed zones.  **I**

    signature found: 1 Time(s)
          validating @0xb4247b50: 117.in-addr.arpa SOA: no valid

Yes, but 117.in-addr.arpa *is* signed [1], so if you're not getting signatures, that's problematic.

So that is not good. This is over port 53, right? I have that open for udp and tcp. My general options section has:

    dnssec-enable yes;
    dnssec-validation yes;
    dnssec-lookaside auto;

    /* Path to ISC DLV key */
    bindkeys-file "/etc/named.iscdlv.key";

    managed-keys-directory "/var/named/dynamic";


    How can I stop the logging of only " no valid signature found"?
     So I can watch for more meaningful events and not so quickly grow
    /var/log/messages?


Logging can be tuned on a per-category (e.g., DNSSEC) basis, including the location to which log messages are sent (e.g., file, syslog, etc.). See the section on logging in the BIND 9 Configuration Reference for more information on how to do this [2].

thanks I will read this AFTER I find out why I am not getting the signature. Perhaps I should check to see if I am getting any sigs? How might I do that?
