Despite contrary views - I DO have reverse authority over my SBC assigned
IP addresses:
I am using a SuSE distributed linux, 9.2 Professional with bind 9.2.4-3
I have x.x.x.120/29 authority, but SBC is telling me that I need to have
an in-addr-arpa for .120 ??
.121 is the slipstream dsl modem
.122 is my first (usable) IP that is my firewall - I do NOT want DNS
there
.123 is my Name Server
/etc/named.conf
zone "29/120.x.x.x.in-addr-arpa" in {
type master;
file "db.x.x.x.120-29"
};
zone "123.x.x.x.in-addr-arpa" in {
type master;
file "db.x.x.x.123"
};
in /var/lib.named
db.x.x.x.123
===usual===
123.x.x.x.in-addr-arpa. IN NS blah-blah.
123.x.x.x.in-addr-arpa. IN PTR more.blah-blah.
db.x.x.x.120-29
===usual===
29/120.x.x.x.in-addr-arpa. IN NS blah-blah.
29/120.x.x.x.in-addr-arpa. IN PTR more.blah-blah.
(Note - same "blah-blah" for both)
I could abandon the "120-29 29/120" construct and replace with just 120
but isn't this then assuming that .120 is my primary ?
Am I missing something obvious ?
Mail is/was working without being flagged "may be forged" which I used to
get before I changed to this configuration, which dnsreport.com reports
as a non-responsive server (and the backups have no authority).
If I need to post full IP/domain, let me know...I'm just being paranoid.
