DDNS: help updates timing out.

   *** From dhcp-server -- To unsubscribe, see the end of this message. ***


Hello folks,

I am running FreeBSD 5.0 with latest ISC bind/dhcpd servers.

I have a problem with DDNS updates which are timing out and i can't seem
to find the cause of those timeouts.

I belive my config files are setup properly because DDNS works partialy
when adding reverse maps.The clients are Win2000 and WinXP.

This is what my logs say:

Here is my config files:

named.conf (just the relevant bits):

key rndc_key {
        algorithm       HMAC-MD5;
        secret

};

controls { inet 127.0.0.1 allow { localhost; } keys { rndc_key; };
           inet 192.168.0.1 allow { blazebox; } keys { rndc_key; };
};

// zone for access to domain
zone "blazebox.db" in {
        type master;
        notify yes;
        allow-update { key rndc_key; 192.168.0.1; };
        file "blazebox.db";
};

// zone for access to domain using ip
zone "0.168.192.in-addr.arpa" in {
        type master;
        notify yes;
        allow-update { key rndc_key; 192.168.0.1; };
        file "db.192.168.0";
};

  ddns-domainname = "blazebox.homeip.net";
  ddns-rev-domainname = "in-addr.arpa";
}

bind has debug enabled and this is what i get from the log:

The db.192.168.0 file:

The reverse map gets set and the journal file is created for the client

The blazebox.db file:

$TTL 3D

#router IN CNAME        blazebox
#proxy  IN CNAME        blazebox

this does not get updated

Finally dhcpd.leases file:

lease 192.168.0.43 {
  starts 0 2003/01/26 22:22:58;
  ends 1 2003/01/27 00:22:58;
  tstp 1 2003/01/27 00:22:58;
  binding state active;
  next binding state free;
  hardware ethernet 00:a0:cc:32:81:44;
  uid "\001\000\240\3142\201D";
  set ddns-rev-name = "43.0.168.192.in-addr.arpa";
  set ddns-client-fqdn = "blaze.homeip.net";
  client-hostname "blaze";
}
lease 192.168.0.254 {
  starts 0 2003/01/26 22:03:20;
  ends 1 2003/01/27 00:03:20;
  tstp 1 2003/01/27 00:03:20;
  binding state active;
  next binding state free;
  hardware ethernet 00:08:74:4c:72:7c;
  uid "\001\000\010tLr|";
  client-hostname "dellbox";
}

The first client runs Win2000 and the second one WinXP.

In addition i use ipfilter but have udp ports 67,68 and 953 open on the lan.

I just don't seem to get DDNS fully working no matter what options and
configurations files i tried from the mailling list.

I would greatly apprecite any help with properly setting up DDNS updates
and bind.

Thank you,

Paul B.
