lame server

There are a log of lame server messages in my system log. This happens because many network administrators ignore the importance of reverse DNS lookup when setting up their DNS zones. In general, if a DNS server is advertized as being authoritative for a particular zone and that server is not authoritative then any DNS server that queries that server for information on that zone will get a lame server error message.

There is a way to get rid of lame server log by adding the following in /etc/named.conf :

logging {
                category lame-servers{ null; };
            };

It works to my satisfaction.
