Start BIND service
Start, stop and restart the named service.
[root@tenouk ~]# /etc/rc.d/init.d/named start
[root@tenouk ~]# /etc/rc.d/init.d/named stop
[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
Setting automatic start for named on runlavel 3 and runlevel 5..
[root@tenouk ~]# /sbin/chkconfig --level 35 named on
Confirmation of automatic start.
[root@tenouk ~]# /sbin/chkconfig --list named
Confirmation of bind.
Use the command example below to test your DNS server functionality.
[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

Similar to Cacti, Munin uses RRDTool to present the output in a pretty graph via web interface. The primary emphasis of Munin is on the plug and play architecture for it’s plugin. There are lot of plugins available for Munin, which will just work out-of-the box without lot of tweaking.
