NAME
named - Internet domain name server
SYNOPSIS
named [-4|-6][
-fgv][-c config-file][-d debuglevel ][
-n ncpus][-p port ][-t directory ]
[
-u user-id ]
DESCRIPTION
named is the Internet domain name system (DNS) server. See RFCs 1033, 1034, and 1035 for more
information on DNS.
The configuration file contains information about where the name server gets its initial data. See
named.conf (4) for details.
With no arguments,
named reads the default configuration file,
/etc/named.conf
, reads any initial
data, and listens for queries.
named requires superuser privileges to execute.
Options
-4 Use IPv4 only, even if the host machine is capable of IPv6.
-6 Use IPv6 only, even if the host machine is capable of IPv4.
-c config-file
Use config-file instead of the default configuration file, /etc/named.conf
. To ensure that
the configuration file can be reloaded after the server has changed its working directory (due
to a possible
directory option in the configuration file), config-file should be an absolute
path name.
-d debuglevel
Set the debug level to debuglevel . Debugging traces from named become more verbose as the
debug level increases.
-f Run the server in the foreground; do not fork and daemonize. The default is to daemonize.
-g Run the server in the foreground and force all logging to standard error.
-n ncpus Create ncpus worker threads to take advantage of multiple CPUs. By default, named
tries to
determine the number of CPUs present and create one thread per CPU. If
named cannot
determine the number of CPUs, it creates a single worker thread.
-p port Listen for queries on port number port . The default is port 53.
-t directory
Change root (chroot())todirectory after processing the command line arguments, but
before reading the configuration file.
Caution: This option should be used with the
-u option, because a chrooted process running
as superuser does not enhance security and could escape a "chroot jail".
-u user-id
Specify the user that the server should run as after it initializes. The value specified may be
either a user name or a numeric user ID.
-v Report the version number and exit.
64-bit Support
The 64-bit
named binary is available in /usr/sbin/named.64.
To start the 64-bit
named binary through startup script, set the following values in the
/etc/rc.config.d/namesvrs_dns file:
NAMED=1
NAMED_64=1
You must also ensure that the kernel tunable maxdsiz_64bit is set appropriately.
NOTE: Kill all the running instances of
named before starting the 64-bit named binary.
Signals
You can use the following signals to reload or shut down the server process, via the
kill command (see
kill (1)):
