New and Changed Features
New Features
Chapter 1 11
Allows any host on a network for which the system has an interface.
An example acl statement is as follows:
acl can_query{ 1.2.3; any;};
The acl statement, can_query, allows queries from any host in the
network 1.2.3.
The include Statement
The include statement inserts a specified file at a particular location in
the configuration file where the include statement is encountered. You
can use the statement to break the configuration file into easily
manageable groups.
The include statement is of the following format:
include path_name;
You can use the following example in the beginning of a BIND
configuration file to include any ACL or key information:
include /etc/security/keys.bind;
include /etc/acls.bind;
You cannot use an include statement within another statement.
Therefore, an entry such as the following is incorrect:
acl internal_hosts{include internal_hosts.acl};
The key Statement
The key statement specifies information about authentication and
authorization.
NOTE The key statement is not implemented in this release. it is checked for
syntax but is otherwise ignored.
The key statement is of the following format:
key key_id { algorithm algorithm_id;
secret secret_string; };
algorithm_id is a string that specifies a security/authentication
algorithm. secret_string is a secret string used by the algorithm.
