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 (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 authentica-
	      tion key allowing rndc to communicate with named with  no	 fur-
	      ther 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.

       -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-
	      confgen.

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

       -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	chan-
	      nel  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
