NAME
ndc - name daemon control interface

SYNOPSYS
ndc directive [ ... ]

DESCRIPTION
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 named as shown by
ps(1).

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

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

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

notrace
Causes named to set its ‘‘tracing level’’ to zero,
closing /var/tmp/named.run if it is open (uses the
USR2 signal.)

querylog
Causes named to toggle the ‘‘query logging’’ fea-
ture, which while on will result in a syslog(3) 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 named to be started, as long as it isn’t
already running.

stop Causes named to be stopped, if it is running.

restart
Causes named to be killed and restarted.

BUGS
Arguments to named are not preserved by restart, or known
by start. Some mechanism for controlling the parameters
and environment should exist.

Implemented as a sh(1) script.
