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 { categ
to help determine the cause when problems happen with DNS and BIND9. Testing Logging Testing resolv.conf The first step in testing BIND9 is to add the nameserver's IP Address to a hosts resolver. The Primary nameserver should be configured as well as

another host to double check things. Refer to DNS Client Configuration for details on bind9 log file adding nameserver addresses to your network clients, and afterwards check that the file /etc/resolv.conf contains (for this example): nameserver 192.168.1.10
Named Log File
nameserver 192.168.1.11 Nameservers that listen at 127.* are responsible for adding their own IP addresses to resolv.conf (using resolvconf). This is done via the file /etc/default/bind9 by changing the line RESOLVCONF=no to RESOLVCONF=yes. You https://forums.opensuse.org/showthread.php/430857-BIND-DNS-error-access-log should also add the IP Address of the Secondary nameserver in case the Primary becomes unavailable. dig If you installed the dnsutils package you can test your setup using the DNS lookup utility dig: After installing BIND9 use dig against the loopback interface to make sure it is listening on port 53. From a terminal prompt: dig -x 127.0.0.1 You should see lines similar to the following in https://help.ubuntu.com/lts/serverguide/dns-troubleshooting.html the command output: ;; Query time: 1 msec ;; SERVER: 192.168.1.10#53(192.168.1.10) If you have configured BIND9 as a Caching nameserver "dig" an outside domain to check the query time: dig ubuntu.com Note the query time toward the end of the command output: ;; Query time: 49 msec After a second dig there should be improvement: ;; Query time: 1 msec ping Now to demonstrate how applications make use of DNS to resolve a host name use the ping utility to send an ICMP echo request. From a terminal prompt enter: ping example.com This tests if the nameserver can resolve the name ns.example.com to an IP Address. The command output should resemble: PING ns.example.com (192.168.1.10) 56(84) bytes of data. 64 bytes from 192.168.1.10: icmp_seq=1 ttl=64 time=0.800 ms 64 bytes from 192.168.1.10: icmp_seq=2 ttl=64 time=0.813 ms named-checkzone A great way to test your zone files is by using the named-checkzone utility installed with the bind9 package. This utility allows you to make sure the configuration is correct before restarting BIND9 and making the changes live. To test our example Forward zone file enter the following from a command prompt: named-checkzone example.com /etc/bind/db.example.com If everything is configured correctly you should see output similar to: zone example.c

It seems like I've done extactly as the fedora guide says. But if I try: $ sudo systemctl start named.service It says that the job failed. I also tried: $ sudo systemctl status named.service It log file gives an error, but it's not very indicative (it says status=failed, code=-1). I would like to know how to debug the files, if there's a tool that says exactly the error that is causing named.service to don't start. edit retag flag offensive close merge delete 1 answer Sort by » oldest newest most voted 1 answered 2013-03-24 13:20:45 +0000 Akshay bind query log 1531 ●8 ●16 ●25 http://www.gofedora.in/ You can use log files after starting/restarting bind to see error messages tail –f /var/log/message Check config file for errors check config file syntax and /etc/named.conf file using following utilities. named-checkconf command is named (BIND) configuration file syntax checking tool. named-checkconf /etc/named.conf Check zone file syntax for errors named-checkzone localhost /var/named/

So my logging section looks like the following: logging { channel default_file { file "/var/log/named/default.log" versions 3 size 5m; severity dynamic; print-time yes; }; channel general_file { file "/var/log/named/general.log" versions 3 size 5m; severity dynamic; print-time yes; }; channel database_file { file "/var/log/named/database.log" versions 3 size 5m; severity dynamic; print-time yes; }; channel security_file { file "/var/log/named/security.log" versions 3 size 5m; severity dynamic; print-time yes; }; channel confi
