[ Q ] How can I use 'nsupdate' ?

[HoKunChung]

Hi,

I am beginner in BIND.

I want to use the 'nsupdate' utility.
but,

===================================================================

[root at ns1 named]# nsupdate
> update add www.thenewland.com 60 CNAME bbb.thenewland.com
>
>
[root at ns1 named]# nslookup bbb.thenewland.com
Server:  ns1.thenewland.com
Address:  203.255.218.8

*** ns1.thenewland.com can't find bbb.thenewland.com: Non-existent
host/domain
[root at ns1 named]#

===================================================================

How can I solve this problem.. ?

and I request the detail manual or tutorial on nsupdate.
I really don't know nsupdate command. I can't understand the manual page
on  "man nsupdate".

thanks in advance.
