rndc-confgen - rndc key generation tool
rndc-confgen [-a] [-A algorithm] [-b keysize]
  [-c keyfile] [-h] [-k keyname] [-p port]
  [-s address] [-t chrootdir] [-u user]
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.
  - -a
- This option sets automatic rndc configuration, which creates a file
      //etc/rndc.key 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.
    If a more elaborate configuration than that generated by
        rndc-confgen -a is required, for example if rndc is to be used
        remotely, run rndc-confgen without the -a option and set
        up rndc.conf and named.conf as directed. 
 
  - -A algorithm
- This option 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-sha256.
 
  - -b keysize
- This option specifies the size of the authentication key in bits. The size
      must be between 1 and 512 bits; the default is the hash size.
 
  - -c keyfile
- This option is used with the -a option to specify an alternate
      location for rndc.key.
 
  - -h
- This option prints a short summary of the options and arguments to
      rndc-confgen.
 
  - -k keyname
- This option specifies the key name of the rndc authentication key.
      This must be a valid domain name. The default is rndc-key.
 
  - -p port
- This option specifies the command channel port where named listens
      for connections from rndc. The default is 953.
 
  - -q
- This option prevets printing the written path in automatic configuration
      mode.
 
  - -s address
- This option 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
- This option is used with the -a option to specify a directory where
      named runs chrooted. An additional copy of the rndc.key is
      written relative to this directory, so that it is found by the chrooted
      named.
 
  - -u user
- This option is used with the -a option to set the owner of the
      generated rndc.key file. 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:
rndc-confgen -a
To print a sample rndc.conf file and the corresponding
    controls and key statements to be manually inserted into
    named.conf, run:
rndc-confgen
