Dynamic updates with nsupdate

Good afternoon all,

I built up a RH9 machine runing BIND 9.3.0, with a single zone.  I want
unsecured dynamic updates to be allowed on this zone.  So far BIND is up and
running and resolving names very nicely, however using nsupdate I am unable
to perform dynamic updates.  nsupdate reports: Communication with server
failed: timed out.  The nsupdate command is:

[root at server-01 sbin]# nsupdate
>update add client-01.domain.com 600 IN A
;Communication with server failed: timed out

The following are my configuration and zone files:

# named.conf
key "rndc-key" {
  algorithm hmac-md5;
  secret "xxxxx";

controls {
  inet port 953
    allow {; } keys { "rndc-key"; };

options {
  directory "/var/named";
  pid-file "/var/run/named-int.pid";
  listen-on port 53 {;; };

zone "domain.com" IN {
  type master;
  allow-transfer { 10/8;; };
  allow-update  { 10/8;; };
  file "/var/named/domain.com.zone";

# domain.com.zone
@    SOA    dns1.domain.com.    hostmaster.domain.com. (
    1, 1D, 30M, 1W, 1H

    IN    NS    dns1.domain.com.
    IN    MX    mail.domain.com

mail    IN    A
dns1    IN    A
www    IN    A
ftp    IN    A
server-01    IN    A

Any advice or information anyone could suggest would be greatly appreciated.

Thank you very much in advance!
