named(8) OSS Shell and Utilities Reference Manual
NAME
named - Starts the nonsecure BIND 9 Internet domain name server
SYNOPSIS
/etc/dns923/named
[ -c config_file ]
[ -d debug_level ]
[ -f ]
[ -g ]
[ -n ncpus ]
[ -p port ]
[ -s ]
[ -t directory ]
[ -u user ]
[ -v ]
[ -x cache_file ]
FLAGS
-c config_file Use config_file as the configuration file instead of the default, /etc/named.conf.
To ensure that reloading the configuration file continues to work after the server
has changed its working directory because of a possible directory option in the
configuration file, config_file should be an absolute pathname.
-d debug_level Set the server’s debug level to debug_level. Debugging traces from named
become more verbose as the debug level increases.
-f Run the server in the foreground (that is, do not run it as a demon).
-g Run the server in the foreground and force all logging to stderr.
-n ncpus Create ncpus worker threads to take advantage of multiple processors. If not
specified, named tries to determine the number of processors present and creates
one thread per processor. If it is unable to determine the number of processors, a
single worker thread is created.
-p port Listen for queries on port port. If not specified, the default is port 53.
-s Write memory usage statistics to stdout on exit.
This option is mainly of interest to BIND 9 developers and might be removed or
changed in a future release.
-t directory Change the working directory to directory after processing the command line
arguments, but before reading the configuration file.
Caution: This option should be used in conjunction with the -u option, because
changing the root directory for a process running as the super ID does not
enhance security on most systems; the way chroot() is defined allows a process
with root user privileges to escape a chroot jail.
-u user setuid() to user after completing privileged operations, such as creating sockets
that listen on privileged ports.
-v Report the version number and exit.
