NAME
       ndc - name daemon control interface

SYNOPSIS
       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/named/namedb/named_dump.db (uses the INT  sig-
              nal).

       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/named/namedb/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/named/namedb/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/named/namedb/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.
