NAME¶
rndc-confgen - rndc key generation toolSYNOPSIS¶
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¶
-aDo 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-confgenSEE ALSO¶
