NAME

       rndc-confgen - rndc key generation tool

SYNOPSIS

       rndc-confgen [ -a ]  [ -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  cor-
       responding  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 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  exist-
	      ing 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 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 authoriazation. 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
