- Enable BIND DNS to start at boot time. [root@collabn1 ~]# chkconfig named on
- Change named directory permissions. [root@collabn1 ~]# touch /var/named/racattack [root@collabn1 ~]# chgrp named /var/named/racattack [root@collabn1 ~]# chmod 664 /var/named/racattack [root@collabn1 ~]# chmod g+w /var/named
- Backup the BIND configuration file. [root@collabn1 ~]# cp /etc/named.conf /etc/named.conf.org
- Change /etc/named.conf permissions. [root@collabn1 ~]# chmod 664 /etc/named.conf Otherwise, the original protection may cause trouble in the restarting named step with write-protection errors in /var/log/messages.
- Run the following command or edit the /etc/named.conf file to change the named configuration manually.
