2N/A<

2N/A generates configuration files
2N/A for <
span><
strong class="command">rndc</
strong></
span>. It can be used as a
2N/A convenient alternative to writing the
2N/A and the corresponding <
span><
strong class="command">controls</
strong></
span>
2N/A and <
span><
strong class="command">key</
strong></
span>
2N/A Alternatively, it can be run with the <
span><
strong class="command">-a</
strong></
span>
2N/A option to set up a <
code class="filename">
rndc.key</
code> file and
2N/A avoid the need for a <
code class="filename">
rndc.conf</
code> file
2N/A and a <
span><
strong class="command">controls</
strong></
span> statement altogether.

2N/A Do automatic <

2N/A This creates a file <

code> (or whatever
2N/A <

span><
strong class="command">rndc</
strong></
span>
2N/A and <
span><
strong class="command">named</
strong></
span> on startup. The
2N/A <
code class="filename">
rndc.key</
code> file defines a default
2N/A command channel and authentication key allowing
2N/A <
span><
strong class="command">rndc</
strong></
span> to communicate with
2N/A <
span><
strong class="command">named</
strong></
span> on the local host
2N/A with no further configuration.
2N/A Running <
span><
strong class="command">rndc-confgen -a</
strong></
span> allows
2N/A BIND 9 and <
span><
strong class="command">rndc</
strong></
span> to be used as
2N/A replacements for BIND 8 and <
span><
strong class="command">ndc</

2N/A with no changes to the existing BIND 8
2N/A If a more elaborate configuration than that
2N/A generated by <
span><
strong class="command">rndc-confgen -a</
strong></
span>
2N/A is required, for example if rndc is to be used remotely,
2N/A you should run <
span><
strong class="command">rndc-confgen</
strong></
span> without
2N/A <

2N/A<

span class="term">-b <

2N/A Specifies the size of the authentication key in bits.
2N/A Must be between 1 and 512 bits; the default is 128.

2N/A authorization. If the operating
2N/A system does not provide a <

2N/A is keyboard input. <

2N/A the name of a character device or file containing random
2N/A data to be used instead of the default. The special value
