NAMErndc-confgen - rndc key generation tool

configuration. This creates a file
was specified as when
was built) that is read by both
on startup. The
file defines a default command channel and authentication key allowing
to communicate with
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.
- Specifies the algorithm to use for the TSIG key. Available choices are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384 and hmac-sha512. The default is hmac-md5.
- Specifies the size of the authentication key in bits. Must be between 1 and 512 bits; the default is the hash size.
- Used with the -a option to specify an alternate location for rndc.key.
- Prints a short summary of the options and arguments to rndc-confgen.
- Specifies the key name of the rndc authentication key. This must be a valid domain name. The default is rndc-key.
- Specifies the command channel port where named listens for connections from rndc. The default is 953.
- 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.
- Specifies the IP address where named listens for command channel connections from rndc. The default is the loopback address 127.0.0.1.
- 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.
- 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
To print a sample rndc.conf file and corresponding controls and key statements to be manually inserted into named.conf, run
