OpenSolaris 2009.06 - man page for rndc.conf (opensolaris section 4)

rndc.conf(4)				   File Formats 			     rndc.conf(4)

NAME
       rndc.conf - rndc configuration file

SYNOPSIS
       rndc.conf

DESCRIPTION
       rndc.conf is the configuration file for rndc, the BIND 9 name server control utility. This
       file has a similar structure and syntax to named.conf. Statements are enclosed  in  braces
       and  terminated	with  a  semi-colon. Clauses in the statements are also semi-colon termi-
       nated. The usual comment styles are supported:

       C style	     /* */

       C++ style     // to end of line

       Unix style    # to end of line

       rndc.conf is much simpler than named.conf. The file  uses  three  statements:  an  options
       statement, a server statement and a key statement.

       The options statement contains three clauses. The default-server clause is followed by the
       name or address of a name server. This host is used when no name server is provided as  an
       argument to rndc. The default-key clause is followed by the name of a key which is identi-
       fied by a key statement. If no keyid is provided on the rndc  command  line,  and  no  key
       clause is found in a matching server statement, this default key will be used to authenti-
       cate the server's commands and responses. The default-port clause is followed by the  port
       to connect to on the remote name server. If no port option is provided on the rndc command
       line, and no port clause is found in a matching server statement, this default  port  will
       be used to connect.

       After  the server keyword, the server statement includes a string which is the hostname or
       address for a name server. The statement has two possible clauses: key and port.  The  key
       name  must  match  the  name of a key statement in the file. The port number specifies the
       port to connect to.

       The key statement begins with an identifying string, the name of the  key.  The	statement
       has  two clauses. algorithm identifies the encryption algorithm for rndc to use; currently
       only HMAC-MD5 is supported. This is followed by a secret clause which contains the base-64
       encoding  of  the  algorithm's  encryption  key.  The base-64 string is enclosed in double
       quotes.

       There are two common ways to generate the base-64 string for the secret. The BIND  9  pro-
       gram  rndc-confgen(1M) can be used to generate a random key, or the mmencode program, also
       known as mimencode, can be used to generate a base-64 string from  known  input.  mmencode
       does  not  ship with BIND 9 but is available on many systems. See the EXAMPLES section for
       sample command lines for each.

EXAMPLES
	 options {
	      default-server  localhost;
	      default-key     samplekey;
	 };

	 server localhost {
	      key	      samplekey;
	 };

	 key samplekey {
	      algorithm hmac-md5;
	      secret
	      "c3Ryb25nIGVub3VnaCBmb3IgYSBtYW4gYnV0IG1hZGUgZm9yIGEgd29tYW4K";
	 };

       In the above example, rndc by default uses the server at localhost (127.0.0.1) and the key
       called  samplekey. Commands to the localhost server use the samplekey key, which must also
       be defined in the server's configuration file with the  same  name  and	secret.  The  key
       statement indicates that samplekey uses the HMAC-MD5 algorithm. Its secret clause contains
       the base-64 encoding of the HMAC-MD5 secret enclosed in double quotes.

       To generate a random secret with rndc-confgen:

	 rndc-confgen

       A complete rndc.conf file, including the randomly generated key, will be  written  to  the
       standard  output.  Commented  out  key  and  controls  statements  for named.conf are also
       printed.

       To generate a base-64 secret with mmencode:

	 echo "known plaintext for a secret" | mmencode

NAME SERVER CONFIGURATION
       The name server must be configured to accept rndc connections and  to  recognize  the  key
       specified  in the rndc.conf file, using the controls statement in named.conf. See the sec-
       tions on the controls statement in the BIND 9 Administrator Reference Manual for details.
