[SOLVED] dhcpd and ddns reverse dns problem

Celyr · 03-25-2012, 05:21 AM

Hi,

This is my dhcpd.conf

Code:

ddns-updates on;
ddns-update-style interim;
ddns-domainname "xxx.lan.";
ddns-rev-domainname "2.168.192.in-addr.arpa.";

...

zone xxx.lan. {
  primary 127.0.0.1;
  key dhcpkey;
}

zone 2.168.192.in-addr.arpa. {
  primary 127.0.0.1;
  key dhcpkey;
}

This is my named.conf:

Code:

zone "xxx.lan" {
        type master;
        file "xxx-lan/xxx.zone";
        allow-update { key dhcpkey; 127.0.0.1; };
};

zone "2.168.192.in-addr.arpa" {
        type master;
        file "xxx-lan/2.168.192.zone";
        allow-update { key dhcpkey; 127.0.0.1; };
};

named-checkconf and named-checkzone like it.
now in xxx.zone i'm having no problem:

Code:

...
$TTL 3600       ; 1 hour
Laptop                  A       192.168.2.103
...

in 2.168.192.zone the result is this one:

Code:

$ORIGIN .
$TTL 86400      ; 1 day
2.168.192.in-addr.arpa  IN SOA  minnie.xxx.lan. hidden.hide.com. (
                                201112194  ; serial
                                7200       ; refresh (2 hours)
                                300        ; retry (5 minutes)
                                604800     ; expire (1 week)
                                60         ; minimum (1 minute)
                                )
                        NS      minnie.xxx.lan.
$ORIGIN 2.168.192.in-addr.arpa.
$TTL 3600       ; 1 hour
103.2.168.192           PTR     Laptop.xxx.lan.
$TTL 86400      ; 1 day
5                       PTR     minnie.xxx.lan.

Wich for 103.2.168.192 is obviusly wrong.
The funny thing is that it used to work, any idea ?
Thank you.

Hi,

it was just a stupid mistake

Code:

ddns-rev-domainname "2.168.192.in-addr.arpa.";

has to be changed in

Code:

ddns-rev-domainname "in-addr.arpa.";

Ty anyway

EDIT: with this change, nothing is working anymore no update at all.

Ok i rewrote all configs by the beginning and now it's working, only god knows why.
