How to enable > logging in /etc/named.conf file, that errors will show in /var/log > directoy? The reason that named logs are usually in /var/lib/named/logs is because named is often run chroot'd. To move it would be painful, but you could always symlink to it inside of /var/log. To manipulate named.conf to add logging options, you can look at the BIND9 ARM or do some googling and look for the logging section. For example, mine has: Code: logging { category update { update_log_file; }; category security { security_log_file; }; category default { log_file; }; category xfer-in { log_file; }; category xfer-out { log_file; }; channel log_file { file "/var/lib/named/log/named.log" size 2M versions 5; severity info; }

This no longer the case and it may appear anywhere convenient. BIND uses syslogd before a valid logging clause is available so named.conf parse errors and other information will appear in /var/log/messages (depending on syslog.conf) prior to, or in the absence of, a valid logging clause. In the case of windows parse errors are written to the Event Log. Only one logging clause can http://www.zytrax.com/books/dns/ch7/logging.html be defined but multiple channels may be defined to stream logs. logging Clause Syntax BIND provides comprehensive logging features. Values in bold type below are keywords; logging { [ channel channel_name { ( file path name [ versions ( number | unlimited ) ] [ size size_spec ] | syslog syslog_facility | stderr | null ); [ severity (critical | error | warning | notice | info | debug [ level ] | dynamic ); ] [ print-category yes | no; ] [ print-severity yes | no; ] [ print-time yes | no; ] }; ] [ category category_name { channel_name ; [ channel_name ; ... ] }; ] ... }; The following notes describe the various fields and values: channel channel_name BIND will accept multiple channel definitions in a single logging statement. 'channel_name' is normally written as a non-space name, for instance, my_channel but it can be written as a quoted string, for instance, "my channel". It is an arbitrary but unique name used to associate the category statement with this channel definition or it may take one of the standard (pre-defined) values below: "default_syslog" log everything to syslog (default logging destination) "default_debug" "default_stderr" output to stderr (normally the console) "null" discard all log entries (write to /dev/null) file 'path_name' is a quoted string defining the absolute path to the logging file, for example, "/var/log/named/namedlog.log".

You can use following tools to troubleshoot bind related problems under UNIX or Linux oses.
Task: Port 53 open and listing requestsBy default BIND listen DNS queries on port 53. So make sure port 53 is open and listing user requests. by running any one of error log the following tests. See if you can telnet to port 53 from remote computer: $ telnet remote-server-ip 53 OR telnet ns1.nixcraft.org domain Output:Trying 192.168.0.5... Connected to ns1.nixcraft.org. Escape character is '^]'. If you cannot connect make sure firewall is not blocking your requests. Next use netstat command to list open and listing port 53 on server itself: $ netstat -tulpn | grep bind error log :53 OR # netstat -atve Output: Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State User Inode tcp 0 0 ns1.nixcraft.org:domain *:* LISTEN named 10386 tcp 0 0 rhx.test.com:domain *:* LISTEN named 10384 tcp 0 0 *:ssh *:* LISTEN root 1785 tcp 0 0 rhx.test.com:rndc *:* LISTEN named 10388 tcp 0 0 rhx.test.com:smtp *:* LISTEN root 1873 tcp 0 0 ns1.nixcraft.org:ssh w2k.nixcraft.org:1057 ESTABLISHED root 10501 tcp 0 0 rhx.test.com:32773 rhx.test.com:domain TIME_WAIT root 0 tcp 0 0 ns1.nixcraft.org:32775 ns1.nixcraft.org:domain TIME_WAIT root 0 tcp 0 0 rhx.test.com:32774 rhx.test.com:domain TIME_WAIT root 0 Make sure iptables firewall is not blocking request on server: # iptables -L -n OR # iptables -L -n | less Make sure named is running: # /etc/init.d/named status If not start named: # chkconfig named on# service named start
