Set up a DNS on Solaris 8(SPARC)

Question

Hi,
We have a ultra 5 machine. I am now trying to install Sun Internet Mail Server. One of the requirement for this is setting up of LDAP server. This does not install until a DNS is found. I intend to install the DNS on the solaris box itself. Can some one help me with the DNS installation and also the Mail Server setup.
Regards
Sunil

I can help you on setting up the dns, but this process
will be very long and I'll explain it to you.
Firstly , Install BIND v.9 from http://www.sunfreeware.com (package)or you can download the source from http://www.isc.org/products/BIND/ .
Installing package is quite simple, download the appropriate file and do #pkgadd -d bind-program
or if you download the source, then you need to configure and make the software.
I assume you have done this. Once you have successfully installed BIND, you need to check on your /etc/named or /var/named directory for the named files.
A sample configuration of BIND is below
$ cat /etc/named.conf
options {
directory "/var/named";
forward only;
listen-on port 53 {
192.168.x.1;
forwarders {
// ISP NS IP's here.
aaa.bbb.ccc.ddd;
allow-query {
192.168.x.0/24;
127.0.0.1/32;
logging {
category lame-servers { null; };
key controlkey {
algorithm hmac-md5;
secret "J5D_hKfy73f&#hfjek&*efke";
controls {
inet 127.0.0.1 allow {
localhost;
} keys {
controlkey;
// zones you wish to master go after this marker ;)
zone "localhost" IN {
type master;
file "caching-example/localhost.zone";
allow-update { none; };
zone "0.0.127.in-addr.arpa" IN {
type master;
file "caching-example/named.local";
allow-update { none; };
When you have created this file (named.conf) then you need to create hosts on your respective directory which you have defined , either /var/named or /etc/named this is where all the hosts will be and you can create this files manually and the format is like below.
Create a file called mydomain.com.hosts
and insert this
$ttl 38400
mydomain.com. IN SOA ns.mydomain.com. dnsadmin.mydomain.com. (
2001030701
3600
900
3600000
3600 )
www IN A 192.168.1.1
server1 IN A 192.168.1.20
ns IN A 192.168.1.2
mydomain.com. IN NS ns.mydomain.com.
mydomain.com. IN MX 10 mail.mydomain.com
For each domain create a file like this, you can add additional hosts in one file above.
Once you have done this you can start the name server , if this dns system is only going to be for internal use, it would be even simpler.
If you have any problems please mail me as posting here will take too much space.
