Correspondence of IP address and hostname
The /etc/hosts file example
# IP Address Hostname Alias
127.0.0.1 localhost
192.168.42.1 apple www
192.168.42.2 desk desk.domain.cxm
Installation of BIND
BIND (Berkeley Internet Name Domain)
[root@tenouk ~]# mount /mnt/cdrom
[root@tenouk ~]# cd /mnt/cdrom/RedHat/RPMS
[root@tenouk ~]# rpm –Uhv bind-9.2.0-8.i386.rpm
[root@tenouk ~]# rpm –Uhv caching-nameserver-7.2.1.noarch.rpm
[root@tenouk ~]# cd /
[root@tenouk ~]# umount /dev/cdrom
Setting of client and server
edit the resolf.conf file to enable the client or server to find the DSN server.
[root@tenouk ~]# vi /etc/resolv.conf
search kimura.com
nameserver 10.10.0.235
Definition of IP address of DNS server which client uses
Setting the DNS server.
[root@tenouk ~]# vi /etc/named.conf
// generated by named-bootconf.pl
options {
directory "/var/named";
/*
* 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.

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
