Yes, I know lots of places don't have DNSSEC signed zones. **I**
have not done mine yet, but I turned on DNSSEC checking on my
server and I am getting all too many messages like:
validating @0xb4247b50: 117.in-addr.arpa NSEC: no valid
signature found: 1 Time(s)
validating @0xb4247b50: 117.in-addr.arpa SOA: no valid
signature found: 1 Time(s)
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?
Well I am not getting this sig authenticated. Per offlist instructions
I did (and got no aa flag):
dig +dnssec 117.in-addr.arpa ptr
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.6 <<>> +dnssec
117.in-addr.arpa ptr
