For more information on the DNS, see \fI\%RFC 1033\fP, +\fI\%RFC 1034\fP, and \fI\%RFC 1035\fP\&. +.sp +When invoked without arguments, \fBnamed\fP reads the default +configuration file \fB@sysconfdir@/named.conf\fP, reads any initial data, and +listens for queries. +.SH OPTIONS +.INDENT 0.0 +.TP +.B \-4 +This option tells \fBnamed\fP to use only IPv4, even if the host machine is capable of IPv6. \fI\%\-4\fP and +\fI\%\-6\fP are mutually exclusive. +.UNINDENT +.INDENT 0.0 +.TP +.B \-6 +This option tells \fBnamed\fP to use only IPv6, even if the host machine is capable of IPv4. \fI\%\-4\fP and +\fI\%\-6\fP are mutually exclusive. +.UNINDENT +.INDENT 0.0 +.TP +.B \-c config\-file +This option tells \fBnamed\fP to use \fBconfig\-file\fP as its configuration file instead of the default, +\fB@sysconfdir@/named.conf\fP\&. To ensure that the configuration file +can be reloaded after the server has changed its working directory +due to to a possible \fBdirectory\fP option in the configuration file, +\fBconfig\-file\fP should be an absolute pathname. +.UNINDENT +.INDENT 0.0 +.TP +.B \-C +This option prints out the default built\-in configuration and exits. +.sp +NOTE: This is for debugging purposes only and is not an +accurate representation of the actual configuration used by \fI\%named\fP +at runtime. +.UNINDENT +.INDENT 0.0 +.TP +.B \-d debug\-level +This option sets the daemon\(aqs debug level to \fBdebug\-level\fP\&. Debugging traces from +\fBnamed\fP become more verbose as the debug level increases. +.UNINDENT +.INDENT 0.0 +.TP +.B \-D string +This option specifies a string that is used to identify a instance of \fBnamed\fP +in a process listing. The contents of \fBstring\fP are not examined. +.UNINDENT +.INDENT 0.0 +.TP +.B \-E engine\-name +When applicable, this option specifies the hardware to use for cryptographic +operations, such as a secure key store used for signing. +.sp +When BIND 9 is built with OpenSSL, this needs to be set to the OpenSSL +engine identifier that drives the cryptographic accelerator or +hardware service module (usually \fBpkcs11\fP). +.UNINDENT +.INDENT 0.0 +.TP +.B \-f +This option runs the server in the foreground (i.e., do not daemonize). +.UNINDENT +.INDENT 0.0 +.TP +.B \-g +This option runs the server in the foreground and forces all logging to \fBstderr\fP\&. +.UNINDENT +.INDENT 0.0 +.TP +.B \-L logfile +This option sets the log to the file \fBlogfile\fP by default, instead of the system log. +.UNINDENT +.INDENT 0.0 +.TP +.B \-M option +This option sets the default (comma\-separated) memory context +options. The possible flags are: +.INDENT 7.0 +.IP \(bu 2 +\fBfill\fP: fill blocks of memory with tag values when they are +allocated or freed, to assist debugging of memory problems; this is +the implicit default if \fBnamed\fP has been compiled with +\fB\-\-enable\-developer\fP\&. +.IP \(bu 2 +\fBnofill\fP: disable the behavior enabled by \fBfill\fP; this is the +implicit default unless \fBnamed\fP has been compiled with +\fB\-\-enable\-developer\fP\&. +.UNINDENT +.UNINDENT +.INDENT 0.0 +.TP +.B \-m flag +This option turns on memory usage debugging flags. Possible flags are \fBusage\fP, +\fBtrace\fP, \fBrecord\fP, \fBsize\fP, and \fBmctx\fP\&. These correspond to the +\fBISC_MEM_DEBUGXXXX\fP flags described in \fB<isc/mem.h>\fP\&. +.UNINDENT +.INDENT 0.0 +.TP +.B \-n #cpus +This option creates \fB#cpus\fP worker threads to take advantage of multiple CPUs. If +not specified, \fBnamed\fP tries to determine the number of CPUs +present and creates one thread per CPU. If it is unable to determine +the number of CPUs, a single worker thread is created. +.UNINDENT +.INDENT 0.0 +.TP +.B \-p value +This option specifies the port(s) on which the server will listen +for queries. If \fBvalue\fP is of the form \fB<portnum>\fP or +\fBdns=<portnum>\fP, the server will listen for DNS queries on +\fBportnum\fP; if not not specified, the default is port 53. If +\fBvalue\fP is of the form \fBtls=<portnum>\fP, the server will +listen for TLS queries on \fBportnum\fP; the default is 853. +If \fBvalue\fP is of the form \fBhttps=<portnum>\fP, the server will +listen for HTTPS queries on \fBportnum\fP; the default is 443. +If \fBvalue\fP is of the form \fBhttp=<portnum>\fP, the server will +listen for HTTP queries on \fBportnum\fP; the default is 80. +.UNINDENT +.INDENT 0.0 +.TP +.B \-s +This option writes memory usage statistics to \fBstdout\fP on exit. +.UNINDENT +.sp +\fBNOTE:\fP +.INDENT 0.0 +.INDENT 3.5 +This option is mainly of interest to BIND 9 developers and may be +removed or changed in a future release. +.UNINDENT +.UNINDENT +.INDENT 0.0 +.TP +.B \-S #max\-socks +This option is deprecated and no longer has any function. +.UNINDENT +.sp +\fBWARNING:\fP +.INDENT 0.0 +.INDENT 3.5 +This option should be unnecessary for the vast majority of users. +The use of this option could even be harmful, because the specified +value may exceed the limitation of the underlying system API. It +is therefore set only when the default configuration causes +exhaustion of file descriptors and the operational environment is +known to support the specified number of sockets. Note also that +the actual maximum number is normally slightly fewer than the +specified value, because \fBnamed\fP reserves some file descriptors +for its internal use. +.UNINDENT +.UNINDENT +.INDENT 0.0 +.TP +.B \-t directory +This option tells \fBnamed\fP to chroot to \fBdirectory\fP after processing the command\-line arguments, but +before reading the configuration file. +.UNINDENT +.sp +\fBWARNING:\fP +.INDENT 0.0 +.INDENT 3.5 +This option should be used in conjunction with the \fI\%\-u\fP option, +as chrooting a process running as root doesn\(aqt enhance security on +most systems; the way \fBchroot\fP is defined allows a process +with root privileges to escape a chroot jail. +.UNINDENT +.UNINDENT +.INDENT 0.0 +.TP +.B \-U #listeners +This option tells \fBnamed\fP the number of \fB#listeners\fP worker threads to listen on, for incoming UDP packets on +each address. If not specified, \fBnamed\fP calculates a default +value based on the number of detected CPUs: 1 for 1 CPU, and the +number of detected CPUs minus one for machines with more than 1 CPU. +This cannot be increased to a value higher than the number of CPUs. +If \fI\%\-n\fP has been set to a higher value than the number of detected +CPUs, then \fI\%\-U\fP may be increased as high as that value, but no +higher. +.UNINDENT +.INDENT 0.0 +.TP +.B \-u user +This option sets the setuid to \fBuser\fP after completing privileged operations, such as +creating sockets that listen on privileged ports. +.UNINDENT +.sp +\fBNOTE:\fP +.INDENT 0.0 +.INDENT 3.5 +On Linux, \fBnamed\fP uses the kernel\(aqs capability mechanism to drop +all root privileges except the ability to \fBbind\fP to a +privileged port and set process resource limits. Unfortunately, +this means that the \fI\%\-u\fP option only works when \fBnamed\fP is run +on kernel 2.2.18 or later, or kernel 2.3.99\-pre3 or later, since +previous kernels did not allow privileges to be retained after +\fBsetuid\fP\&. +.UNINDENT +.UNINDENT +.INDENT 0.0 +.TP +.B \-v +This option reports the version number and exits. +.UNINDENT +.INDENT 0.0 +.TP +.B \-V +This option reports the version number, build options, supported +cryptographics algorithms, and exits. +.UNINDENT +.INDENT 0.0 +.TP +.B \-X lock\-file +This option acquires a lock on the specified file at runtime; this helps to +prevent duplicate \fBnamed\fP instances from running simultaneously. +Use of this option overrides the \fBlock\-file\fP option in +\fI\%named.conf\fP\&. If set to \fBnone\fP, the lock file check is disabled. +.UNINDENT +.SH SIGNALS +.sp +In routine operation, signals should not be used to control the +nameserver; \fI\%rndc\fP should be used instead. +.INDENT 0.0 +.TP +.B SIGHUP +This signal forces a reload of the server. +.TP +.B SIGINT, SIGTERM +These signals shut down the server. +.UNINDENT +.sp +The result of sending any other signals to the server is undefined. +.SH CONFIGURATION +.sp +The \fBnamed\fP configuration file is too complex to describe in detail +here. A complete description is provided in the BIND 9 Administrator +Reference Manual. +.sp +\fBnamed\fP inherits the \fBumask\fP (file creation mode mask) from the +parent process. If files created by \fBnamed\fP, such as journal files, +need to have custom permissions, the \fBumask\fP should be set explicitly +in the script used to start the \fBnamed\fP process. +.SH FILES +.INDENT 0.0 +.TP +.B \fB@sysconfdir@/named.conf\fP +The default configuration file. +.TP +.B \fB@runstatedir@/named.pid\fP +The default process\-id file. +.UNINDENT +.SH SEE ALSO +.sp +\fI\%RFC 1033\fP, \fI\%RFC 1034\fP, \fI\%RFC 1035\fP, \fI\%named\-checkconf(8)\fP, \fI\%named\-checkzone(8)\fP, \fI\%rndc(8)\fP, \fI\%named.conf(5)\fP, BIND 9 Administrator Reference Manual. +.SH AUTHOR +Internet Systems Consortium +.SH COPYRIGHT +2023, Internet Systems Consortium +.\" Generated by docutils manpage writer. +. |
