Very Computer

My DNS refuses to do reverse lookups for this config, why?

/etc/named.conf

options {
...stuff...

Quote:};

...other zones...

zone "168.192.in-addr.arpa" {
        type master;
        file "zone/192.168";
        notify no;

Quote:};

/var/named/zone/192.168

...header...

8.1      PTR      hareid-gw.mydomain.com.
9.1      PTR      kleven-gw.mydomain.com.
10.1     PTR      mmv-gw.mydomain.com.
11.1     PTR      sande-gw.mydomain.com.
12.1     PTR      larsnes-gw.mydomain.com.

If I use this config it worx ok:

/etc/named.conf

options {
...stuff...

Quote:};

...other zones...

zone "8.168.192.in-addr.arpa" {
        type master;
        file "zone/192.168.8";
        notify no;

Quote:};

zone "9.168.192.in-addr.arpa" {
        type master;
        file "zone/192.168.9";
        notify no;

Quote:};

/var/named/zone/192.168.8

...header...

8.1      PTR      hareid-gw.mydomain.com.

/var/named/zone/192.168.9

...header...

9.1      PTR      kleven-gw.mydomain.com.

I take it your goal is to keep all your PTR records in one file instead of
delegating each subnet from this upper level in-addr.arpa zone.

The above will never work without the proper delegation "first" for each
subnet. (like your second example) Anyway, to overide the need to
delegate each subnet, specify the FULL in-addr.arpa name. i.e.

1.8.168.192.in-addr.arpa.   86400   PTR  hareid-gw.mydomain.com.
1.9.168.192.in-addr.arpa.   86400   PTR  kleven-gw.mydomain.com.
1.10.168.192.in-addr.arpa. 86400   PTR  mmv-gw.mydomain.com.
1.11.168.192.in-addr.arpa. 86400   PTR  sande-gw.mydomain.com.
1.21.168.192.in-addr.apra. 86400   PTR  larsnes-gw.mydomain.com.

OOPS!!! Forgot the "IN" in my last reply.Try...

1.8.168.192.in-addr.arpa.   86400   IN PTR  hareid-gw.mydomain.com.
1.9.168.192.in-addr.arpa.   86400   IN PTR  kleven-gw.mydomain.com.
1.10.168.192.in-addr.arpa. 86400   IN PTR  mmv-gw.mydomain.com.
1.11.168.192.in-addr.arpa. 86400   IN PTR  sande-gw.mydomain.com.
1.21.168.192.in-addr.apra. 86400   IN PTR  larsnes-gw.mydomain.com.
