[root@tenouk ~]# rpm –Uhv caching-nameserver-7.2.1.noarch.rpm

[root@tenouk ~]# cd /

[root@tenouk ~]# umount /dev/cdrom

/*

* If there is a firewall between you and nameservers you want

* to talk to, you might need to uncomment the query-source

* directive below. Previous versions of BIND always asked

* questions using port 53, but BIND 8.1 uses an unprivileged

* port by default.

*/

// query-source address * port 53;

};

[root@tenouk ~]# /etc/rc.d/init.d/named restart

or

[root@tenouk ~]# /sbin/service named start

[root@tenouk ~]# /sbin/service named stop

[root@tenouk ~]# /sbin/service named restart

[root@tenouk ~]# /sbin/chkconfig --level 35 named on

Confirmation of automatic start.

[root@tenouk ~]# /sbin/chkconfig --list named

[root@tenouk ~]# ping 10.10.0.235

[root@tenouk ~]# ping 10.10.0.236

[root@tenouk ~]# ping jmtist20

[root@tenouk ~]# ping compaq

[root@tenouk ~]# ping jmtist20.kimura.com

[root@tenouk ~]# ping compaq.kimura.com

[root@tenouk ~]# nslookup jmtist20.kimura.com

[root@tenouk ~]# nslookup compaq.kimura.com

[root@tenouk ~]# nslookup 10.10.0.235

[root@tenouk ~]# nslookup 10.10.0.236
