I'm trying to configure a DHCP and DNS using a rndc-key, according to these tutorial:
Dynamic-DNS with openSUSE 11.2 - YouTube!

I could do it fine on a VM with openSUSE 12.2. I tried again with openSUSE 12.3 and I'm having these problem:
named: request has invalid signatures: TSIG rndc-key tsig verify failure (BADKEY)

How do I debug this type of error? I tried both creating a custom key and using the default /etc/rndc.key and with both approaches I'm having the same error.

Any ideas?

Thanks a lot!
