problem with nsupdate

[Oliver Block]

Hello everybody,

I was trying to get nsupdate creating an A Record for a subdomain. I was 
following one of the tutorials out there in the web.

After I finished everything I received the following (manually obscured) 
output from nsupdate -d:

Creating key...
Outgoing update query:
;; ->>HEADER<<- opcode: UPDATE, status: NOERROR, id:      0
;; flags: ; ZONE: 0, PREREQ: 0, UPDATE: 0, ADDITIONAL: 0

1231377216 300 16 Ud1iyORRRZT4KXn67kFAzg== 60017 NOERROR 0

; Communication with server failed: operation canceled


I CAN SEE NO ERROR MESSAGE. But did not work much neither with dns nor 
nsupdate. Can anyone give me a hint what the problem may be?

BTW: Please cc me, as I am not subscribed.
