How to use DNS dynamic update on openSUSE 11?

Hello,

I have an DHCP and DNS servers that use dynamic update with TSIG signature.

I have an openSUSE 11 desktop that use dhcp client. It is able to get an IP lease from the DHCP server, but it can’t update the DNS RR A and PTR on the DNS server. I don’t seeing where to use the TSIG signature on this desktop.

Any ideas, please?

TIA,
Vinicius.
