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 state-
ment 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 authentica-
tion 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 lis-
tens 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 con-
trols and key statements to be manually inserted into
named.conf, run
