Hi Andrea,
Start with two computer.
Pick up a system which is going to be your server. Don't touch any other system.
Install bind on that system (we have hp 712 system as dns server for 500 hosts). Copy your current hosts file on /etc.
Say your domain named is xyz.com and your server named is andrea. And you are on 10.15.0.0 network.
Then edit /etc/named.conf file
options {
check-names master ignore;
check-names response ignore;
check-names slave ignore;
directory "/usr/local/named"; #you can change this. This dir will hold your all
database files.
forwarders {
198.6.100.25;
};
};
zone "0.0.127.in-addr.arpa" {
type master;
file "named.local"; # you can even change this file name.
};
zone "." {
type hint;
file "named.cache"; # you can change this file name too.
};
zone "xyz.com" {
type master;
file "hosts.xyy.com"; # this is your main db file
};
zone "15.10.in-addr.arpa" {
type master;
file "db.10.15"; # this is your reverse look up file
};
Then run hosts_to_named command with options. Your hosts.xyz.com file will looks like this
; hosts.xyz.com
;
$TTL 86400
@ IN SOA andrea.xyz.com. root@xyz.com. (
2375 ; Serial No
21601 ; Refresh every 6 hours
3600 ; Retry 1 hour
1728000 ; Expire 20 days
21600 ) ; Minimum 6 hours
; this two are my servers
IN NS andrea.xyz.com.
IN NS sachin.xyz.com
; this are my normal hosts
localhost IN A 127.0.0.
1achilles IN A 10.15.47.1
adair IN A 10.15.32.20
aggie IN A 10.15.32.41
Then edit your /etc/resolv.conf file
domain xyz.com
nameserver 10.15.1.1 # ip_of andrea
oh yes and don???t forget to start named.
Edit the /etc/nsswitch.conf file to
hosts: dns file
andrea# nslookup andrea (should return proper result with stating that it is from dns)
If all this work then on client you have to change only /etc/nsswitch.conf and /etc/resolv.conf file only.
