ndc

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.
