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

Confirmation of bind.

[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
