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@server-01 sbin]# nsupdate
>update add 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/";
listen-on port 53 {;; };

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

@ SOA (
1, 1D, 30M, 1W, 1H


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!
