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



NAME
       rndc-confgen - rndc key generation tool

SYNOPSIS
       rndc-confgen  [ -a ]  [ -b keysize ]  [ -c keyfile ]  [ -h ]  [ -k key-
       name ]  [ -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  corre-
       sponding  controls  and key statements in named.conf by hand.  Alterna-
       tively, 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 alto-
       gether.

OPTIONS
       -a     Do automatic rndc configuration.  This creates a  file  rndc.key
              in  /etc/namedb  that is read by both rndc and named on startup.
              The rndc.key file defines a default command channel and  authen-
              tication  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-con-
              fgen.

       -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 con-
              nections from rndc.  The default is 953.

       -r randomfile
              Specifies a source of random data for generating the  authoriza-
              tion.  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
