Bug 605826

Description of problem:
Excessive logging of common DNS events clogs syslog

Version-Release number of selected component (if applicable):
bind-9.7.0-10.P2.fc13.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Default installation
2.
3.
  
Actual results:
Thousands of resolver, lame-server, and edns-disabled messages clog syslog, without contributing useful information.

Expected results:
Only infrequent important messages should go to syslog.

Additional info:
Default behavior of named should change.  Given the current state of the DNS ecosystem, messages in categories resolver, lame-server, edns-disabled, and queries should simply be discarded.  Routine messages should go to the default_debug channel, and only potentially actionable messages should go to the default_syslog channel. 

Please adjust the default /etc/named.conf to use (or include) more practical logging specification, something like the following:

logging {

// Channels default_syslog, default_debug, default_stderr, and null
// should be predefined, but adjust default_debug here

        channel default_debug {
                file "data/named.run";
                severity dynamic;
                print-time yes;
                print-category yes;
                print-severity no;
        };

        category default { default_syslog; };
        category general { default_syslog; };
        category database { default_debug; };
        category security { default_syslog; };
        category config { default_syslog; };
        category resolver { null; };
        category xfer-in { default_syslog; };
        category xfer-out { default_syslog; };
        category notify { default_debug; };
        category client { default_debug; };
        category unmatched { default_debug; };
        category network { default_debug; };
        category update { default_syslog; };
        category update-security { default_syslog; };
        category queries { null; };
        category query-errors { default_debug; };
        category dispatch { default_debug; };
        category dnssec { default_debug; };
        category lame-servers { null; };
        category delegation-only { default_debug; };
        category edns-disabled { null; };
};
