Hello,
So, you have a lot of people using your server for name name server queries ? That uses your bandwidth ? Not a problem here is the step to overcome that.
Open the file /etc/named.conf
vi /etc/named.conf
and add below lines by replacing the old allow-recursion and allow-transfer lines
allow-transfer {“none”;};
allow-recursion {“none”;};
recursion no;restart the named service using the below command and you are done.
/etc/init.d/named restart
You test the same using dig command, you should find the following output.
[root@ns399932 ~]# dig @127.0.0.1 google.com A ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-20.P1.el5_8.1 <<>> @127.0.0.1 google.com A ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<
Thank you for watching
