RNDC-CONFGEN(8)               BIND9               RNDC-CONFGEN(8)


NAME
       rndc-confgen - rndc key generation tool

SYNOPSIS
       rndc-confgen [-a] [-b keysize] [-c keyfile] [-h]
                    [-k keyname] [-p port] [-r randomfile]
                    [-s address] [-t chrootdir] [-u user]

DESCRIPTION
       rndc-confgen generates configuration files for rndc. It
       can be used as a convenient alternative to writing the
       rndc.conf file and the corresponding controls and key
       statements in named.conf by hand. Alternatively, it can be
       run with the -a option to set up a rndc.key file and avoid
       the need for a rndc.conf file and a controls statement
       altogether.

OPTIONS
       -a
           Do automatic rndc configuration. This creates a file
           rndc.key in /etc (or whatever sysconfdir was specified
           as when BIND was built) that is read by both rndc and
           named on startup. The rndc.key file defines a default
           command channel and authentication key allowing rndc
           to communicate with named on the local host with no
           further configuration.

           Running rndc-confgen -a allows BIND 9 and rndc to be
           used as drop-in replacements for BIND 8 and ndc, with
           no changes to the existing BIND 8 named.conf file.

           If a more elaborate configuration than that generated
           by rndc-confgen -a is required, for example if rndc is
           to be used remotely, you should run rndc-confgen
           without the -a option and set up a rndc.conf and
           named.conf as directed.

       -b keysize
           Specifies the size of the authentication key in bits.
           Must be between 1 and 512 bits; the default is 128.

       -c keyfile
           Used with the -a option to specify an alternate
           location for rndc.key.

       -h
           Prints a short summary of the options and arguments to
           rndc-confgen.

       -k keyname
           Specifies the key name of the rndc authentication key.
           This must be a valid domain name. The default is
           rndc-key.

       -p port
           Specifies the command channel port where named listens
           for connections from rndc. The default is 953.

       -r randomfile
           Specifies a source of random data for generating the
           authorization. If the operating system does not
           provide a /dev/random or equivalent device, the
           default source of randomness is keyboard input.
           randomdev specifies the name of a character device or
           file containing random data to be used instead of the
           default. The special value keyboard indicates that
           keyboard input should be used.

       -s address
           Specifies the IP address where named listens for
           command channel connections from rndc. The default is
           the loopback address 127.0.0.1.

       -t chrootdir
           Used with the -a option to specify a directory where
           named will run chrooted. An additional copy of the
           rndc.key will be written relative to this directory so
           that it will be found by the chrooted named.

       -u user
           Used with the -a option to set the owner of the
           rndc.key file generated. If -t is also specified only
           the file in the chroot area has its owner changed.

EXAMPLES
       To allow rndc to be used with no manual configuration, run

       rndc-confgen -a

       To print a sample rndc.conf file and corresponding
       controls and key statements to be manually inserted into
       named.conf, run

       rndc-confgen
