4. chkconfig time-stream on

To sync same time on client

1. rdate -s <Serversip>


  

Configure RNDC SERVER

1. rm -rf /etc/rndc.key
2. rndc-confgen -a
3. vim /etc/named.conf                     //Add entires to this file
4. vim /etc/rndc.conf                      //Add entries to this file
5. scp /etc/rndc.conf 192.168.0.20:/etc
6. pkill named
7. service named restart
8. rndc reload


Configure RNDC CLIENT

1. rdate -s <serverip>
2. yum install bind caching-nameserver -y
3. vim  /etc/rndc.key
4. rndc reload
5. rndc stop
