+.SH "DESCRIPTION"
+.PP
+\fBnamed\fR
+is a Domain Name System (DNS) server, part of the BIND 9 distribution from ISC. For more information on the DNS, see RFCs 1033, 1034, and 1035.
+.PP
+When invoked without arguments,
+\fBnamed\fR
+will read the default configuration file
+\fI/etc/named.conf\fR, read any initial data, and listen for queries.
+.SH "OPTIONS"
+.PP
+\-4
+.RS 4
+Use IPv4 only even if the host machine is capable of IPv6.
+\fB\-4\fR
+and
+\fB\-6\fR
+are mutually exclusive.
+.RE
+.PP
+\-6
+.RS 4
+Use IPv6 only even if the host machine is capable of IPv4.
+\fB\-4\fR
+and
+\fB\-6\fR
+are mutually exclusive.
+.RE
+.PP
+\-c \fIconfig\-file\fR
+.RS 4
+Use
+\fIconfig\-file\fR
+as the configuration file instead of the default,
+\fI/etc/named.conf\fR. To ensure that reloading the configuration file continues to work after the server has changed its working directory due to to a possible
+\fBdirectory\fR
+option in the configuration file,
+\fIconfig\-file\fR
+should be an absolute pathname.
+.RE
+.PP
+\-d \fIdebug\-level\fR
+.RS 4
+Set the daemon's debug level to
+\fIdebug\-level\fR. Debugging traces from
+\fBnamed\fR
+become more verbose as the debug level increases.
+.RE
+.PP
+\-f
+.RS 4
+Run the server in the foreground (i.e. do not daemonize).
+.RE
+.PP
+\-g
+.RS 4
+Run the server in the foreground and force all logging to
+\fIstderr\fR.
+.RE
+.PP
+\-m \fIflag\fR
+.RS 4
+Turn on memory usage debugging flags. Possible flags are
+\fIusage\fR,
+\fItrace\fR,
+\fIrecord\fR,
+\fIsize\fR, and
+\fImctx\fR. These correspond to the ISC_MEM_DEBUGXXXX flags described in
+\fI<isc/mem.h>\fR.
+.RE
+.PP
+\-n \fI#cpus\fR
+.RS 4
+Create
+\fI#cpus\fR
+worker threads to take advantage of multiple CPUs. If not specified,
+\fBnamed\fR
+will try to determine the number of CPUs present and create one thread per CPU. If it is unable to determine the number of CPUs, a single worker thread will be created.
+.RE
+.PP
+\-p \fIport\fR
+.RS 4
+Listen for queries on port
+\fIport\fR. If not specified, the default is port 53.
+.RE
+.PP
+\-s
+.RS 4
+Write memory usage statistics to
+\fIstdout\fR
+on exit.
+.RS
+.B "Note:"
+This option is mainly of interest to BIND 9 developers and may be removed or changed in a future release.
+.RE
+.RE
+.PP
+\-t \fIdirectory\fR
+.RS 4
+Chroot to
+\fIdirectory\fR
+after processing the command line arguments, but before reading the configuration file.
+.RS
+.B "Warning:"
+This option should be used in conjunction with the
+\fB\-u\fR
+option, as chrooting a process running as root doesn't enhance security on most systems; the way
+\fBchroot(2)\fR
+is defined allows a process with root privileges to escape a chroot jail.
+.RE
+.RE
+.PP
+\-u \fIuser\fR
+.RS 4
+Setuid to
+\fIuser\fR
+after completing privileged operations, such as creating sockets that listen on privileged ports.
+.RS
+.B "Note:"
+On Linux,
+\fBnamed\fR
+uses the kernel's capability mechanism to drop all root privileges except the ability to
+\fBbind(2)\fR
+to a privileged port and set process resource limits. Unfortunately, this means that the
+\fB\-u\fR
+option only works when
+\fBnamed\fR
+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(2)\fR.
+.RE
+.RE
+.PP
+\-v
+.RS 4
+Report the version number and exit.
+.RE
+.PP
+\-x \fIcache\-file\fR
+.RS 4
+Load data from
+\fIcache\-file\fR
+into the cache of the default view.
+.RS
+.B "Warning:"
+This option must not be used. It is only of interest to BIND 9 developers and may be removed or changed in a future release.
+.RE
+.RE
+.SH "SIGNALS"
+.PP
+In routine operation, signals should not be used to control the nameserver;
+\fBrndc\fR
+should be used instead.
+.PP
+SIGHUP
+.RS 4
+Force a reload of the server.
+.RE
+.PP
+SIGINT, SIGTERM
+.RS 4
+Shut down the server.
+.RE
+.PP
+The result of sending any other signals to the server is undefined.
+.SH "CONFIGURATION"
+.PP
+The
+\fBnamed\fR
+configuration file is too complex to describe in detail here. A complete description is provided in the
+BIND 9 Administrator Reference Manual.
+.SH "FILES"
+.PP
+\fI/etc/named.conf\fR
+.RS 4
+The default configuration file.
+.RE
+.PP
+\fI/var/run/named.pid\fR
+.RS 4
+The default process\-id file.
