RNDC-CONFGEN(8)			     BIND9		       RNDC-CONFGEN(8)

       rndc-confgen - rndc key generation tool

       rndc-confgen [-a] [-b keysize] [-c keyfile] [-h]	[-k keyname] [-p port]
		    [-r	randomfile] [-s	address] [-t chrootdir]	[-u user]

       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

	   Do automatic	rndc configuration. This creates a file	rndc.key in
	   /etc/namedb (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.

       -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

	   Prints a short summary of the options and arguments to

       -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

       -s address
	   Specifies the IP address where named	listens	for command channel
	   connections from rndc. The default is the loopback address

       -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

       -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.

       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
