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

DESCRIPTION
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 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 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-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 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 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
