Lame servers messages

November 17th, 2008 — Linux

Lame server is when a NS record for a domain specifies a server which is not authoritative for that domain.

To keep your logs clean from lame server messages (/var/log/messages):

[...]
Nov 16 15:10:50 srv named[99]: lame server resolving 'abc.com' (in 'abc.com'?): 1.2.3.4#53
Nov 16 15:10:50 srv named[99]: lame server resolving 'abc.com' (in 'abc.com'?): 1.2.3.4#53
Nov 16 15:10:50 srv named[99]: lame server resolving 'abc.com' (in 'abc.com'?): 1.2.3.4#53
Nov 16 15:10:50 srv named[99]: lame server resolving 'abc.com' (in 'abc.com'?): 1.2.3.4#53
Nov 16 19:43:25 srv named[99]: lame server resolving 'abc.com' (in 'abc.com'?): 1.2.3.4#53
Nov 16 19:43:25 srv named[99]: lame server resolving 'abc.com' (in 'abc.com'?): 1.2.3.4#53
[...]

Edit your /etc/named.conf and add:

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

Then restart bind daemon.
