[David Gonzalez]

Hello BIND,

  Could anyone tell me where can i find a good DDNS Howto?.

  I haven't been able to get it running.

  Thanks

  here are my configs:

dhcpd.conf

        ddns-updates on;
        ddns-update-style interim;
        ignore client-updates;
        include "/etc/named.keys";

subnet 192.168.1.0 netmask 255.255.255.0 {
        option routers 192.168.1.1;
        option subnet-mask 255.255.255.0;
        option domain-name "tuxcafe.lan";
        option domain-name-servers 192.168.1.100, 200.21.200.2;

        ddns-domainname "tuxcafe.lan";
        ddns-rev-domainname "1.168.192.in-addr.arpa";

        range dynamic-bootp 192.168.1.80 192.168.1.100;
        default-lease-time 1600;
        max-lease-time 2200;

        # Adding zone information

        zone tucafe.lan. {primary 127.0.0.1; key DHCP_UPDATER;}
        zone 1.168.192.in-addr.arpa. {primary 127.0.0.1; key DHCP_UPDATER;}

logs show this:

May 14 17:16:47 xaero dhcpd: Unable to add forward map from zorlag.tuxcafe.lan to 192.168.1.99: not a zone
May 14 17:16:47 xaero dhcpd: DHCPREQUEST for 192.168.1.99 from 00:0c:29:e6:9d:a5 (zorlag) via eth0

Does anyone have a clue?.

Thanks
