Question DDNS Secure only & unix client


Hi!

I want to set up a dhcp server (ISC), with a windows DNS server.
I want dynamic dns updates (ddns).

All works fine if i select "secure and non secure" ddns on windows server (that's a proof that my config file on dhcp is right), but if i select "secure only", my Unix machine can't add dns entries (dhcp server or client), but my windows clients can.

I joined my unix dhcp server and my unix client to my domain :
net ads test join tells me that "Join is OK"
(and if i try wbinfo -g or wbinfo-u, all is right)

My Domain Controller is Microsoft Active Directory, and i see my unix computers in "computers"

I have a good kerberos ticket in my unix clients (i check it with klist)

My /etc/dhclient.conf :
send fqdn.fqdn "hostname.domainname"; (with the real hostname, and the real domainname of course)
send fqdn.encoded on;
send fqdn.server-update off;


I don't know what to check now...

Can somebody help me?
Thank you!

Actually, ddns = dynamic DNS, can be set up to any DNS server.

I have my own Windows DNS Server, I have my own Unix DHCP Server...

I can't find someone, who did "secure only" DDNS on Windows server for Unix host...

help me, please

Hi,
I have no answer for your question but... I need your help.
I've successfully installed an ubuntu 8.04 server with a static private IP address behind a firewall that does natting to a static public IP address.

I'd like to have a Dynamic dns server for my domain so that:
- my server can assign a virtual domain (say "ciccio.provaprova.it") to a dynamic public address (every user has ADSL connection to Internet, so his IP address changes from time to time and it's assigned randomly from his connection isp (I am NOT his connection isp)

- any user of my domain (provaprova.it) can have a windows utility that, when his ip address change, can tell to my server to dynamically update dns informations and to link ciccio.provaprova.it to the new IP address.

In other words: I want to offer a dynamic dns service to my users (such as dyndns.com or others on Internet).
I don't want my users to use those services (even if they are free).

I think it's what you have done with windows 2003 and linux servers.
Can you tell me step by step how to do this?

If it is too complex please tell me what I have to do: maybe a different linux distribution (I can also use another different server!) or... tell me!

Thank you very very very much!!!
