Configuring and Managing BIND
5.3 Configuring the BIND Server (BIND 8.1)
Table 5–3 (Cont.) Path Name Options
Option Description
pid-file The path name of the file in which the server writes its process
ID. If not specified, the default is TCPIP$BIND_SERVER.PID.
The
pid-file is used by programs like TCPIP$BIND_
SERVER_CONTROL.EXE that want to send signals to the
running name server.
statistics-file The path name of the file the server appends
statistics to when it receives a SIGILL signal
(TCPIP$BIND_SERVER_CONTROL.EXE stats). If
not specified, the default is TCPIP$BIND_SERVER_
STATISTICS.LOG.
Example 5–1 shows how to specify path name options with the options
statement.
Example 5–1 Path Name Options
options {
directory "SYS$SPECIFIC:[TCPIP$BIND]";
dump-file "TCPIP$BIND_SERVER_ZONES_DUMP.DB";
memstatistics-file "TCPIP$BIND_SERVER_MEMSTATISTICS.LOG";
pid-file "TCPIP$BIND_SERVER.PID";
statistics-file "TCPIP$BIND_SERVER_STATISTICS.LOG"
};
5.3.2.2 Boolean Options
Table 5–4 lists the Boolean options.
Table 5–4 Boolean Options
Option Description
auth-nxdomain If yes, then the AA bit is always set on NXDOMAIN responses,
even if the server is not actually authoritative. The default
is yes. Do not turn off
auth-nxdomain unless you are
knowledgeable about the option, as some older versions of
software may respond unpredictably.
deallocate-on-exit If yes, then when the server exits, it deallocates every object
it allocated, and then writes a memory-usage report to the
memstatistics-file . The default is no, because it is faster
to let the operating system clean up. The
deallocate-on-
exit
option is useful for detecting memory leaks.
fake-iquery If yes, the server simulates the obsolete DNS query type
IQUERY. The default is no.
fetch-glue If yes (the default), the server fetches ‘‘glue’’ resource records it
does not have when constructing the additional data section of
a response.
no-fetch-glue can be used with no-recursion
to prevent the server’s cache from growing or becoming
corrupted (at the cost of requiring more work from the client).
host-statistics If yes, then statistics are kept for every host that the name
server interacts with. The default is no. Note that turning on
host-statistics can consume huge amounts of memory.
