Forwarders
If your local DNS server cannot answer a request, it tries to forward the request to a
Forwarder, if configured so. This forwarder may be added manually to the Forwarder
List. If the forwarder is not static like in dial-up connections, netconfig handles the
configuration. For more information about netconfig, see man 8 netconfig. server
Basic Options
In this section, set basic server options. From the Option menu, select the desired item
then specify the value in the corresponding entry field. Include the new entry by selecting
Add.
Logging
To set what the DNS server should log and how, select Logging. Under Log Type,
specify where the DNS server should write the log data. Use the systemwide log file
/var/log/messages by selecting System Log or specify a different file by selecting
File. In the latter case, additionally specify a name, the maximum file size in megabytes
and the number of logfile versions to store.
Further options are available under Additional Logging. Enabling Log All DNS Queries
causes every query to be logged, in which case the log file could grow extremely large.
For this reason, it is not a good idea to enable this option for other than debugging
purposes. To log the data traffic during zone updates between DHCP and DNS server,
enable Log Zone Updates. To log the data traffic during a zone transfer from master to
slave, enable Log Zone Transfer. See Figure 21.4, "DNS Server: Logging" (page 285).
