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

NAME
       rndc-confgen - rndc key generation tool

SYNOPSIS
       rrnnddcc-ccoonnffggeenn [-aa] [-bb keysize] [-cc keyfile] [-hh] [-kk keyname] [-pp port]
                    [-rr randomfile] [-ss address] [-tt chrootdir] [-uu user]

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

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

           Running rrnnddcc-ccoonnffggeenn -aa allows BIND 9 and rrnnddcc to be used as
           drop-in replacements for BIND 8 and nnddcc, with no changes to the
           existing BIND 8 named.conf file.

           If a more elaborate configuration than that generated by
           rrnnddcc-ccoonnffggeenn -aa is required, for example if rndc is to be used
           remotely, you should run rrnnddcc-ccoonnffggeenn without the -aa 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 -aa option to specify an alternate location for
           rndc.key.

       -h
           Prints a short summary of the options and arguments to
           rrnnddcc-ccoonnffggeenn.

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

       -p port
           Specifies the command channel port where nnaammeedd listens for
           connections from rrnnddcc. 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 nnaammeedd listens for command channel
           connections from rrnnddcc. The default is the loopback address
           127.0.0.1.

       -t chrootdir
           Used with the -aa option to specify a directory where nnaammeedd 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
           nnaammeedd.

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

EEXXAAMMPPLLEESS
       To allow rrnnddcc to be used with no manual configuration, run

       rrnnddcc-ccoonnffggeenn -aa

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

       rrnnddcc-ccoonnffggeenn
