Improved Logging Mechanism
In BIND 9.2.0, the logging mechanism is established only when the entire configuration file has
been parsed. In BIND 8.1.2, it was established as soon as the logging statement was parsed.
When the server is starting up, all logging messages regarding syntax errors in the configuration
file go to the default channels or to standard error if the "-g" option was specified. The log files
are no longer dumped in the /var/tmp directory, they are put in the local directory.
Extended Configuration Syntax and Options
BIND 9.2.0 configuration is broadly similar to BIND 8.1.2, however, there are a few new areas
of configuration such as views.
BIND 8.1.2 configuration files should work with few alterations in BIND 9.2.0, although the more
complex configurations should be reviewed to check that they are more efficiently implemented
using the new features found in BIND 9.2.0.
BIND 4.9.7 configuration files need to be converted to the new format using the shell script
/usr/bin/named-bootconf.sh.
New Options in "options" Statement
The following lists and describes the new options added in "options" statement:
• allow-recursion
This option specifies which hosts are allowed to make recursive queries through the server. If
not specified, recursive queries from all hosts are allowed.
• max-transfer-idle-in
This option is used to terminate inbound zone transfers making no progress in the specified
period. Default is 60 mins.
• max-transfer-time-out
This option is used to terminate outbound zone transfers running longer than the specified
time. Default is 120 mins.
• max-transfer-idle-out
This option is used to terminate out bound zone transfers making no progress in the specified
period. Default is 60 mins.
• max-cache-ttl
This option is used to specify maximum time to cache positive answers. Default is 7 days.
• max-ncache-ttl
This option is used to specify maximum time to cache negative answers. Default is 3 hrs. This
value should not exceed 7 days and will be truncated to 7 days if a longer time period is
specified.
• transfer-source
This option specifies the IPv4 address to use for inbound zone updates, which is also the
source address to use for refresh queries and forwarded dynamic updates. If not set, it defaults
to a system-controlled value which will usually be the address of the interface "closest to" the
remote end.
