RNDC-CONFGEN(8)RNDC-CONFGEN(8)NAMErndc-confgen - rndc key generation tool
SYNOPSISrndc-confgen [ -a ] [ -b keysize ] [ -c keyfile ] [ -h ] [ -k keyname
] [ -p port ] [ -r randomfile ] [ -s address ] [ -t chrootdir ] [ -u
user ]
DESCRIPTIONrndc-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 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.
-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.

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