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.
