ndc8bind

Usage

Overview

This command allows the name server administrator to send various signals to the name server, or to restart it. Zero or more directives may be given, from the following list:

status

Displays the current status of @INDOT@named(@SYS_OPS_EXT@) as shown by ps(@CMD_EXT@).

dumpdb

Causes @INDOT@named to dump its database and cache to /var/named/named_dump.db (uses the INT signal.)

reload

Causes @INDOT@named to check the serial numbers of all primary and secondary zones and to reload those that have changed (uses the HUP signal.)

stats

Causes @INDOT@named to dump its statistics to /var/named/named.stats (uses the IOT or ABRT signal.)

trace

Causes @INDOT@named to increment its “tracing level” by one. Whenever the tracing level is nonzero, trace information will be written to /var/named/named.run. Higher tracing levels result in more detailed information. (Uses the USR1 signal.)

notrace

Causes @INDOT@named to set its “tracing level” to zero, closing /var/named/named.run, if it is open (uses the USR2 signal.)

querylog

Causes @INDOT@named to toggle the “query logging” feature, which while on will result in a syslog(@SYSCALL_EXT@) of each incoming query (uses the WINCH signal.) Note that query logging consumes quite a lot of log file space. This directive may also be given as qrylog.

start

Causes @INDOT@named to be started, as long as it isn't already running.

stop

Causes @INDOT@named to be stopped, if it is running.

restart

Causes @INDOT@named to be killed and restarted.
