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
