Hi,
I have a colo machine with 1 ip address and several domain names, I need
to confirm that I am setting up bind9 correctly. (note. not using actual
machine name and ip).
name of server: foo.dom-a.com
domains: dom-a.com, dom-b.com
named.conf (the interesting part):
zone "." {
type hint;
file "named.root";
};
zone "dom-a.com" in {
type master;
file "master/db.dom-a.com";
allow-query { any; };
};
zone "dom-b.com" in {
type master;
file "master/db.dom-b.com";
allow-query { any; };
};
db.dom-a.com:
$TTL 86400
dom-a.com. IN SOA ns hostmaster (...omitted...)
IN NS ns
IN MX 10 mail
@ IN A 1.2.3.4
localhost IN A 127.0.0.1
ns IN CNAME @
mail IN CNAME @
www IN CNAME @
foo IN CNAME @
db.dom-b.com:
$TTL 86400
dom-b.com. IN SOA ns hostmaster (...omitted...)
IN NS ns
IN MX 10 mail
@ IN A 1.2.3.4 ; SAME IP AS dom-a.com
localhost IN A 127.0.0.1
ns IN CNAME @
mail IN CNAME @
www IN CNAME @
notes:
1. dom-a has an extra host foo
2. there is only 1 ip address
Question #2: how do I set up the reverse lookup zone file ?
Obviously the colo is not going to give me a subnet, in fact there is
only 1 ip. In this case, do I just setup a
zone "3.2.1.in-addr.arpa"
and a
4 IN PTR foo.dom-a.com.
?
Thank you.
