     ndc — name daemon control interface

     ndc directive [...]

     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(8) 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” feature, which while
               on will result in a syslog(2) 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

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

     restart   Causes named to be killed and restarted.

     Arguments to named are not preserved by restart, or known by start.

     Some mechanism for controlling the parameters and environment should

     Implemented as a sh(1) script.
