Hi Paul.
Thank you for replying :-)
I've Googled and only ever seen examples of named.conf's with one
reverse zone (yet multiple forward zones [1, 2, ..., n] for which the
reverse zone is SOA). I'm trying to provide primary nameserver services
to multiple domains such that:
/etc/named.conf looks like:
-----8<----------8<----------8<----------8<----------8<-----
zone "yyy.xxx.www.in-addr.arpa" {
type master;
file "/var/named/yyy.xxx.www.rev";
allow-query { any; };
};
-----8<----------8<----------8<----------8<----------8<-----
and /var/named/yyy.xxx.www.rev looks like:
-----8<----------8<----------8<----------8<----------8<-----
$TTL 3600
$ORIGIN yyy.xxx.www.IN-ADDR.ARPA.
;
@ IN SOA ns1.domainname_0.tld. admin.domainname_0.tld. (
0603240000 ; serial
10800 ; refresh
3600 ; retry
604800 ; expire
10800 ; minimum
)
;
IN NS ns1.domainname_0.tld.
;
IN NS ns1.domainname_1.tld.
...
IN NS ns1.domainname_n.tld.
;
vvv.www.xxx.yyy IN PTR ns1.domainname_0.tld.
;
vvv.www.xxx.yyy IN PTR ns1.domainname_1.tld.
...
vvv.www.xxx.yyy IN PTR ns1.domainname_n.tld.
;
-----8<----------8<----------8<----------8<----------8<-----
I'm going to guess that I can either adopt the following naming scheme
by changing the generic:
file "/var/named/yyy.xxx.www.rev";
to:
file "/var/named/yyy.xxx.www.domainname_0.rev";
in /var/named.conf say,
-----8<----------8<----------8<----------8<----------8<-----
zone "yyy.xxx.www.in-addr.arpa" {
type master;
file "/var/named/yyy.xxx.www.domainname_0.rev";
allow-query { any; };
};
zone "yyy.xxx.www.in-addr.arpa" {
type master;
file "/var/named/yyy.xxx.www.domainname_1.rev";
allow-query { any; };
};
...
zone "yyy.xxx.www.in-addr.arpa" {
type master;
file "/var/named/yyy.xxx.www.domainname_n.rev";
allow-query { any; };
};
-----8<----------8<----------8<----------8<----------8<-----
or change statements in reverse zones by having one 'type master;' and
the others 'type slave;'?
Thanks again for your help!
