ddns+dhcp

4 May 2004

      Hallo

Versuche seit einigen Tage DHCP mit DDNS zum laufen zu bringen.
Funktioniert auch alles bis auf die Tatsache dass die reverse Zone nicht
aktualisiert wird. Im log steht:

Arbeite mit Suse 9.0 und habe die Anleitung vom DDNS Howto befolgt. Meine
dhcpd.conf und named.conf schauen folgendermaßen aus:

ddns-update-style interim;
ddns-updates on;
ddns-domainname "localnet.lan";
update-static-leases true;
authoritative;
include "/etc/named.keys";

authoritative;
default-lease-time 600;
max-lease-time 7200;
# Lokal
subnet 192.168.1.0 netmask 255.255.255.0 {
        option domain-name "localnet.lan";
        option domain-name-servers 192.168.1.25;
        option routers 192.168.1.254;
        range 192.168.1.65 192.168.1.70;
        zone localnet.lan. { primary 127.0.0.1; key DHCP_UPDATER; }
        zone 1.168.192.in-addr-arpa. { primary 127.0.0.1; key DHCP_UPDATER; }
        }

named.conf

options {
        directory "/var/lib/named";
        /*
         * If there is a firewall between you and nameservers you want
         * to talk to, you might need to uncomment the query-source

         */
        // query-source address * port 53;
        forward first;
        forwarders {
                194.25.2.129;
                };
};
//

//
zone "." IN {
        type hint;
        file "root.hint";
};

zone "localhost" IN {
        type master;
        file "localhost.zone";
};

zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "named.local";
};

include "/etc/named.keys";

zone "localnet.lan" {
        type master;
        file "/var/lib/named/dyn/localnet.lan.zone";
        allow-update {key DHCP_UPDATER; };
};
zone "1.168.192.in-addr.arpa" {
        type master;
        file "/var/lib/named/dyn/1.168.192.zone";
        allow-update {key DHCP_UPDATER; };
};

Bin für jeden Hinweis dankbar.
