DNS Server: Logging This section allows you to set options concern-
ing the contents and the location of the DNS server’s log data. Un-
der ‘Log Type’, specify where the DNS server should write its log
data. Use the system-wide log file /var/log/messages by select-
ing ‘Log to System Log’ orspecify a different file by selecting ‘Log to
File’. In the latter case, additionally specify the maximum file size in
megabytes and the number of log files to store.
Further options are available under ‘Additional Logging’: Enabling
‘Log Named 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 21.11.

DNS Server: ACLs Use this window to define ACLs (access control lists)
to enforce access restrictions. After providing a distinct name un-
der ‘Name’, specify an IP address (with or without netmask) under
‘Value’, in the following fashion:
{ 10.10/16; }
