ndc(1Mtcp)
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(1Mtcp)
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(3G)
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.
Arguments to
named
are not preserved by restart, or known by start.
Some mechanism for controlling the parameters and environment should exist.
ndc is implemented as a
sh(1)
script.
