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

       rndc-confgen - rndc key generation tool

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

       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

       -a Do automatic rndc configuration. This creates a file rndc.key in
          /etc/namedb (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

       -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

       -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

       -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.

       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
