Zero or more directives may be given, from the following list: .TP .B status Displays the current status of .B @INDOT@named as shown by .BR ps (1). .TP .B dumpdb Causes .B @INDOT@named to dump its database and cache to .B /var/tmp/named_dump.db (uses the INT signal.) .TP .B reload Causes .B @INDOT@named to check the serial numbers of all primary and secondary zones and to reload those that have changed (uses the HUP signal.) .TP .B stats Causes .B @INDOT@named to dump its statistics to .B /var/tmp/named.stats (uses the IOT or ABRT signal.) .TP .B trace Causes .B @INDOT@named to increment its ``tracing level'' by one. Whenever the tracing level is nonzero, trace information will be written to .BR /var/tmp/named.run . Higher tracing levels result in more detailed information. (Uses the USR1 signal.) .TP .B notrace Causes .B @INDOT@named to set its ``tracing level'' to zero, closing .B /var/tmp/named.run if it is open (uses the USR2 signal.) .TP .B querylog Causes .B @INDOT@named to toggle the ``query logging'' feature, which while on will result in a .BR 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 .BR qrylog . .TP .B start Causes .B @INDOT@named to be started, as long as it isn't already running. .TP .B stop Causes .B @INDOT@named to be stopped, if it is running. .TP .B restart Causes .B @INDOT@named to be killed and restarted. .SH BUGS Arguments to .B @INDOT@named are not preserved by .BR restart , or known by .BR start . Some mechanism for controlling the parameters and environment should exist. .PP Implemented as a .BR sh (1) script. .SH AUTHOR Paul Vixie (Internet Software Consortium) .SH SEE ALSO @INDOT@named(@SYS_OPS_EXT@), @INDOT@named.reload(@SYS_OPS_EXT@), @INDOT@named.restart(@SYS_OPS_EXT@)
