Hello everyone -
I run bind version 9.8.2 on CentOS 6.5. The daily logwatch run sends me the
following items. Are any of these a real problem?
============
checkhints: extra NS 'A.ROOT-SERVERS.NET' in hints: 170 Time(s)
checkhints: extra NS 'B.ROOT-SERVERS.NET' in hints: 170 Time(s)

clients-per-query decreased to 10: 2 Time(s)
(repeated many time with various numbers)
===================
The hints file DOES contain two entries for each of the ROOT-SERVERS. One is
the ipv4 address and the other is the ipv6 address. I use the hints file
downloaded from http://www.internic.net/domain/named.root .
The hints file does NOT contain any entries for the opennic.glue or
dnslibre.info servers. However, when I run "rndc -all", the output shows that
bind has entries for those servers. The names will resolve and answer ping.
I searched all over trying to find information on the clients-per-query
setting. My named.conf file does not contain an entry for clients-per-query.
Is there some detailed documentation on this setting? What does it really do?
Three more notes: 1) I see no problems in daily operation. All web browsing
works as does resolution for local machines. 2) This bind server does not get
queries from outside my local network. 3) I use OpenNIC as the "forwarders"
servers. I used to use OpenDNS until they stopped handling Yahoo email
correctly.
Thanks - Bill Gee
