rndc-confgen(8)

NAME

   rndc-confgen - rndc key generation tool

SYNOPSIS

   rndc-confgen [-a] [-A algorithm] [-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.

   -A algorithm
       Specifies the algorithm to use for the TSIG key. Available choices
       are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384 and
       hmac-sha512. The default is hmac-md5.

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

   -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
