<title>DESCRIPTION</title>

<para><command>rndc-confgen</command>

generates configuration files

for <command>rndc</command>. It can be used as a

convenient alternative to writing the

<filename>rndc.conf</filename> file

and the corresponding <command>controls</command>

and <command>key</command>

statements in <filename>named.conf</filename> by hand.

Alternatively, it can be run with the <command>-a</command>

option to set up a <filename>rndc.key</filename> file and

avoid the need for a <filename>rndc.conf</filename> file

and a <command>controls</command> statement altogether.

</para>

<title>OPTIONS</title>

<variablelist>

<varlistentry>

<term>-a</term>

<listitem>

<para>

Do automatic <command>rndc</command> configuration.

This creates a file <filename>rndc.key</filename>

in <filename>/etc</filename> (or whatever

<varname>sysconfdir</varname>

was specified as when <acronym>BIND</acronym> was

built)

that is read by both <command>rndc</command>

and <command>named</command> on startup. The

<filename>rndc.key</filename> file defines a default

command channel and authentication key allowing

<command>rndc</command> to communicate with

<command>named</command> on the local host

with no further configuration.

</para>

<para>

Running <command>rndc-confgen -a</command> allows

BIND 9 and <command>rndc</command> to be used as

drop-in

replacements for BIND 8 and <command>ndc</command>,

with no changes to the existing BIND 8

<filename>named.conf</filename> file.

</para>

<para>

If a more elaborate configuration than that

generated by <command>rndc-confgen -a</command>

is required, for example if rndc is to be used remotely,

you should run <command>rndc-confgen</command> without

the

<command>-a</command> option and set up a

<filename>rndc.conf</filename> and

<filename>named.conf</filename>

as directed.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-A <replaceable class="parameter">algorithm</replaceable></term>

<listitem>

<para>

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.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-b <replaceable class="parameter">keysize</replaceable></term>

<listitem>

<para>

Specifies the size of the authentication key in bits.

Must be between 1 and 512 bits; the default is the

hash size.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-c <replaceable class="parameter">keyfile</replaceable></term>

<listitem>

<para>

Used with the <command>-a</command> option to specify

an alternate location for <filename>rndc.key</filename>.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-h</term>

<listitem>

<para>

Prints a short summary of the options and arguments to

<command>rndc-confgen</command>.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-k <replaceable class="parameter">keyname</replaceable></term>

<listitem>

<para>

Specifies the key name of the rndc authentication key.

This must be a valid domain name.

The default is <constant>rndc-key</constant>.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-p <replaceable class="parameter">port</replaceable></term>

<listitem>

<para>

Specifies the command channel port where <command>named</command>

listens for connections from <command>rndc</command>.

The default is 953.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-r <replaceable class="parameter">randomfile</replaceable></term>

<listitem>

<para>

Specifies a source of random data for generating the

authorization. If the operating

system does not provide a <filename>/dev/random</filename>

or equivalent device, the default source of randomness

is keyboard input. <filename>randomdev</filename>

specifies

the name of a character device or file containing random

data to be used instead of the default. The special value

<filename>keyboard</filename> indicates that keyboard

input should be used.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-s <replaceable class="parameter">address</replaceable></term>

<listitem>

<para>

Specifies the IP address where <command>named</command>

listens for command channel connections from

<command>rndc</command>. The default is the loopback

address 127.0.0.1.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-t <replaceable class="parameter">chrootdir</replaceable></term>

<listitem>

<para>

Used with the <command>-a</command> option to specify

a directory where <command>named</command> will run

chrooted. An additional copy of the <filename>rndc.key</filename>

will be written relative to this directory so that

it will be found by the chrooted <command>named</command>.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-u <replaceable class="parameter">user</replaceable></term>

<listitem>

<para>

Used with the <command>-a</command> option to set the

owner

of the <filename>rndc.key</filename> file generated.

If

<command>-t</command> is also specified only the file

in

the chroot area has its owner changed.
