named-checkconf checks the syntax only of a named ( bind ) configuration file. The file is parsed and checked for syntax errors, along with all files included by it. If there are no file is specified with command, \/etc\/named.conf is read by default.<\/p>\n
Tip 1: Check your dns ( bind ) configuration .<\/p>\n
In case of any changes done in bind configuration, I recommend to check dns configuration file before restarting service.<\/p>\n
# named-checkconf \/etc\/named.conf
\nIf bind is running in chroot environment use below command also along with above command<\/p>\n
# named-checkconf -t \/var\/named\/chroot \/etc\/named.conf
\nAbove command will show nothing if there are no error found in configuration file. In case of any error will displayed as output.<\/p>\n
Tip 2: Check bind zone file using named-checkzone.<\/p>\n
To check the syntax of zone file use command as below. It will show result in both cases.<\/p>\n
# named-checkzone rmohan.net \/var\/named\/rmohan.net.db
\nSample output;<\/p>\n
zone rmohan.net\/IN: loaded serial 3013040200
\nOK
\nTip 3: Check configuration file in older version of bind.<\/p>\n
If you are using older version of bind, you can have also check the configuration using below command.<\/p>\n
# service named configtest
\nSample Outut:<\/p>\n
zone tool.com\/IN: loaded serial 42
\nzone localhost\/IN: loaded serial 42
\nzone 1.168.192.in-addr.arpa\/IN: loaded serial 1997022700
