I am experiencing some weird errors when I attempt to freeze a DNS zone:
[EMAIL PROTECTED] ~]# rndc freeze
rndc: 'freeze' failed: unexpected end of input
[EMAIL PROTECTED] ~]# rndc freeze t0e.org
rndc: 'freeze' failed: not found
[EMAIL PROTECTED] ~]# rndc freeze t0e.org internal
rndc: 'freeze' failed: unknown class/type
Usage:
[EMAIL PROTECTED] ~]# rndc
...
freeze zone [class [view]]
Suspend updates to a dynamic zone.
I am using bind and dhcpd for my local network. My OS is CentOS 5. I
have frozen zones before fine. The only difference I can think of is
instead of using some sample zone files off of the internet, I am using
the ones provided with bind, and they use "views". I can query the DNS
server fine, I can even do dynamic updates from DHCP clients. The only
strange issue I run into is I am no longer able to freeze the zones, so
I can update the zones, without breaking the dynamic updates.
I used the sample named.conf file, and made the following modifications
(see attached):
1. options: listen-on
2. view localhost-resolver: my zones
3. view internal: my zones, commented out sample zones
4. include rndc key file
5. view external: commented all out
I am also using the following files:
cp /usr/share/doc/bind-9.3.3/sample/etc/named.conf /etc/named.conf
cp /usr/share/doc/bind-9.3.3/sample/etc/named.root.hints
cp /usr/share/doc/bind-9.3.3/sample/etc/named.rfc1912.zones
/etc/named.rfc1912.zones
cp /usr/share/doc/bind-9.3.3/sample/etc/rndc.conf /etc/rndc.key
chown root:named /etc/named*
cat /usr/share/doc/bind-9.3.3/sample/var/named/named.root
/var/named/named.root
chown root:named /var/named/named.root
Any thoughts or ideas as to what can be done to correct this?
Thanks in advance,
Kenneth
