@INDOT_U@NDC(@SYS_OPS_EXT_U@)

NAME
@INDOT@ndc - name daemon control interface

SYNOPSIS
@INDOT@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 @INDOT@named as shown by ps(1).

dumpdb
    Causes @INDOT@named to dump its database and cache to /var/tmp/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/tmp/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/tmp/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/tmp/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(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 @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.

BUGS
Arguments to @INDOT@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.
