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 client-01.domain.com 600 IN A 10.0.0.5
>

;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 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "rndc-key"; };
};

options {
directory "/var/named";
pid-file "/var/run/named-int.pid";
listen-on port 53 { 10.0.0.1; 127.0.0.1; };
};

zone "domain.com" IN {
type master;
allow-transfer { 10/8; 127.0.0.1; };
allow-update { 10/8; 127.0.0.1; };
file "/var/named/domain.com.zone";
};

# domain.com.zone
$TTL 1H
@ 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 10.0.0.2
dns1 IN A 10.0.0.1
www IN A 10.0.0.3
ftp IN A 10.0.0.3
server-01 IN A 10.0.0.4

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

Thank you very much in advance!
