Contoh Kasus :

Domain : biner.com
IP server : 192.168.254.1

1. Install linux Suse 10.2
Siapkan PC untuk install linux suse, install dengan mode text.

2. Setting IP
yast -> Network Device -> Network Card -> Traditional Method with ifup -> pilih card -> edit -> Statistic Address Setup
-> Ip Address : 192.168.254.1 -> Subnet Mask : 255.255.255.0 -> Next -> Finish

3. Hostname
yast -> Network Service -> DNs and Hostname -> Hostname : server -> Domain Name : biner.com -> Finish

4. Install aplikasi
untuk DNS :
bind
DNS Server

untuk webserver:
apache
yast2-http-server

tool:
mc

5. aktifkan IP forwarding
Yast -> Network Service -> routing

# This is a sample configuration file for the name server BIND 9. It works as
# a caching only name server without modification.
#
# A sample configuration for setting up your own domain can be found in
# /usr/share/doc/packages/bind/sample-config.
#
# A description of all available options can be found in
# /usr/share/doc/packages/bind/misc/options.

# The directory statement defines the name server’s working directory

directory “/var/lib/named”;

# Write dump and statistics file to the log subdirectory. The
# pathenames are relative to the chroot jail.

# The forwarders record contains a list of servers to which queries
# should be forwarded. Enable this line and modify the IP address to
# your provider’s name server. Up to three servers may be listed.

#forwarders { 192.0.2.1; 192.0.2.2; };

# Enable the next entry to prefer usage of the name server declared in
# the forwarders section.

#forward first;

# The listen-on record contains a list of local network interfaces to
# listen on. Optionally the port can be specified. Default is to
# listen on all interfaces found on your system. The default port is
# 53.

#listen-on port 53 { 127.0.0.1; };

# The listen-on-v6 record enables or disables listening on IPv6
# interfaces. Allowed values are ‘any’ and ‘none’ or a list of
# addresses.

# The next three statements may be needed if a firewall stands between
# the local server and the internet.

#query-source address * port 53;
#transfer-source * port 53;
#notify-source * port 53;

# The allow-query record contains a list of networks or IP addresses
# to accept and deny queries from. The default is to allow queries
# from all hosts.

#allow-query { 127.0.0.1; };

# If notify is set to yes (default), notify messages are sent to other
# name servers when the the zone data is changed. Instead of setting
# a global ‘notify’ statement in the ‘options’ section, a separate
# ‘notify’ can be added to each zone definition.

# To configure named’s logging remove the leading ‘#’ characters of the
# following examples.

#
# # Don’t log lame server messages.
# category lame-servers { null; };

# The following zone definitions don’t need any modification. The first one
# is the definition of the root name servers. The second one defines
# localhost while the third defines the reverse lookup for localhost.

zone “localhost” in {
type master;
file “localhost.zone”;

};

# Include the meta include file generated by createNamedConfInclude. This
# includes all files as configured in NAMED_CONF_INCLUDE_FILES from
# /etc/sysconfig/named

include “/etc/named.conf.include”;

# You can insert further zone records for your own domains below or create
# single files in /etc/named.d/ and add the file names to
# NAMED_CONF_INCLUDE_FILES.
# See /usr/share/doc/packages/bind/README.SUSE for more details.

2. Tekan tombol Insert untuk edit file named.conf, tambahkan dibawah ini

D. Cek DNS
1. Restart bind
# /etc/init.d/named restart
Shutting down name server BIND done
Starting name server BIND done

(jika masih belum muncul seperti di atas masih salah cek lagi penulisannya )
2. cek host
# host server.biner.com
server.biner.com has address 192.168.254.1

3. cek server
# nslookup server
Server: 127.0.0.1
Address: 127.0.0.1#53
