see if it can help you. Gurus please correct me if I am wrong. I hope I did not miss
out anything while writing this.

I want to create the following domains:
linux.mydomain.com 192.168.1.100
www.mydomain.com 192.168.1.95
ftp.mydomain.com 192.168.1.96
My m/c ip is 192.168.1.100.
1. Create ip alias.
a. cd /etc/sysconfig/network-scripts
cp ifcfg-eth0 ifcfg-eth0:0
cp ifcfg-eth0 ifcfg-eth0:1
vi ifcfg-eth0:0
ip address = 192.168.1.95
vi ifcfg-eth0:1
ip address = 192.168.1.96
2. Restart network service.
/etc/rc.d/init.d/network restart
3. Test the ip address by 'pinging' & 'ifconfig' . u
should be able to see & ping all ipaddresses.
4. Install name files from CD if it is not installed
(I don't remember which files).
5. vi /etc/named.conf. add the following lines. BE
CAREFUL OF THE SYNTEX.
zone "mydomain.com" {
type master;
file "named.forward";
};
zone "1.168.192.in-addr.arpa" {
type master;
file "named.reverse";
};
6. cp /var/named/named.local /var/named/named.forward
7. cp /var/named/named.local /var/named/named.reverse
8. vi /var/named/named.forward & change it as follows.
BE CAREFUL OF THE SYNTEX
@ IN SOA mydomain.com. root.mydomain.com.
( 2000120800 ; serial
28800 ; refresh
14400 ; retry
3600000 ; expire
86400 ; default_ttl
)
@ IN NS linux.mydomain.com.
@ IN NS linux.mydomain.com.
@ IN A 192.168.1.100
linux IN A 192.168.1.100
www IN A 192.168.1.95
ftp IN A 192.168.1.96
9. vi /var/named/named.reverse & change it as
follows. BE CAREFUL OF THE SYNTEX
@ IN SOA localhost. root.localhost.
( 2000120800 ; serial
28800 ; refresh
14400 ; retry
3600000 ; expire
86400 ; default_ttl
)
@ IN NS localhost.
100 IN PTR linux.mydomain.com.
95 IN PTR www.mydomain.com.
96 IN PTR ftp.mydomain.com.
10. vi /etc/resolv.conf
search localhost
nameserver 192.168.1.100
11. Restart named . /etc/rc.d/init.d/named restart
12. Test it by nslookup.
