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
