New Options in “Zone” Statement
The following lists the new options added in “Zone” statement:
• forwarders
This option can be used to specify the IP addresses to be used for forwarding.
The forwarding facility can be used to create a large site-wide cache on a few
servers, reducing traffic over links to external nameservers. This facility also
allows queries by servers that do not have direct access to the Internet, but wish
to look up exterior names. Forwarding occurs only on those queries for which
the server is not authoritative and does not have an answer in its cache.
The forwarders option is specified in the /etc/named.conf file as:
[ forwarders { ip_addr [port ip_port] ;
[ ip_addr [port ip_port] ; ... ] }; ]
• allow-update
This option can be used to specify which hosts are allowed to submit Dynamic
DNS updates for master zones. By default, updates from all hosts are denied.
NOTE allow-update option is not applicable for slave zones. Refer to the
named.conf(4) man page for more information.
rndc-confgen
rndc-confgen can be used to generate rndc.conf, the configuration file for
rndc. Alternatively, it can also be run with the -a option to set up a rndc.key file
thus avoiding the need for a rndc.conf file and a control statement.
rndc-confgen is run on the command line as:
rndc-confgen [-a] [-b keysize] [-c keyfile] [-h] [-k keyname]
[-p port] [-r randomfile] [-s address] [-t chrootdir] [-u use]
Where
“-a” option is used to configure rndc automatically. This creates a file rndc.key
in /etc which is read by both rndc and named on start-up.
